IPad for poor vision. Train your eyesight on iPad

Many owners of iOS devices look at the iPhone and iPad screen for several hours every day, but not everyone knows about correct setting display will reduce eye strain and make interaction with the gadget more comfortable for vision. With the help of various settings, you can increase the size of the text on the iPhone or iPad screen, change the type of font, enlarge fragments of text using a magnifying glass, etc.

Increase the text size

You don't have to strain your eyes when trying to read text on your iPhone or iPad screen. If necessary, its size can be increased in several ways.

Using the option “ Text size», You can increase (or decrease) the font size. To do this, go to the menu " Settings» → « Screen and brightness» → « Text size»And drag the slider to decrease or increase the font size.

If you want to enlarge not only the text, but also other elements (icons and buttons), go to the menu “ Settings» → « Screen and brightness» → « Display enlargement". This section contains two possible options — « Increased"And" Standard". When the first option is activated, the icons will be displayed larger. Remember that each time you enable / disable the option, you will need to reboot the device.

Set the font to bold

Of course, text size matters, but boldness is also important for many users. You can change the font thickness as follows: open the menu " Settings» → « Screen and brightness» → « Bold font»And drag the slider to the desired position. After the iOS device restarts, everything (from icons to text in messages) will appear thicker and darker.

Zoom in on a specific area of \u200b\u200bthe iPhone or iPad screen

IOS has a zoom function that allows you to enlarge areas of the device's screen using the function "Increase"... To enable this functionality, open “ Settings» → « The main» → « Universal access» → « Magnification". To call the function, you need to double-tap the screen with two fingers. You can move the magnifier around the screen and double-tap to resize it.

In addition, iOS has a virtual magnifier that allows you to magnify various objects using the camera. We talked about how to set up and use a virtual magnifier.

Highlight buttons

In iOS 6, Apple redesigned the buttons to resemble just words on the screen. Fortunately, iOS has the ability to reshape buttons to give them a more classic look. To do this, open the section " Settings» → « The main» → « Universal access» → « Button shapes". After making changes, buttons and other clickable items on the screen will either be underlined or displayed as a rectangle.

To reduce eye strain in iOS 10, you can use an overlay light filters... This feature works on all iOS devices: iPhone 6s, iPhone 6s Plus, iPhone SE and other models that support iOS 10.

Light filters are different from a feature introduced in iOS 9.

A task Night shift - to exclude the blue radiation of the screen, which acts on the nervous system as a pathogen. As a result, the display is tinted orange-beige.

But this is not the best way out. There is something more interesting.

Make your screen blood red, you won't regret it

Light filter makes the screen completely red. And this solution has many advantages.

Our eyes distinguish red color worse than others. Optical deception occurs: a screen with a red filter forces the eyes to perceive the picture in the same way as when using a lower brightness level. Thus, you can look at the red screen in a completely dark room without discomfort.

Scientists conducted a series of experiments on rodents, exposing them to light of different color spectrum: white, blue and red. Under the influence blue light the animals fell into depression. White light did not have a negative impact. Act red light not inferior to total darkness in which the test subjects felt comfortable.

The phenomenon of minimal exposure to red light on the retina is explained by the peculiarity ganglion cellsthat practically do not react to it. The use of red lights on the streets is no coincidence: red light has a positive effect on human well-being.

Breaking away from iPhone screen, you instantly adapt to the dark. This happens faster than in Night Shift mode or when the filter is not used.

How to turn on the Light Filter

Function Light filters available on all iOS devices running iOS 10.

1 ... We open Settings -\u003e General -\u003e Accessibility.

2. Selecting an item Display adaptation -\u003e Light filters.

3. Turn on the slider Light filter... A drop-down list will open.

4. Looking for an item Shade... Check the box opposite, and drag the two sliders below to the maximum.

The screen turns into a deep red color. It looks creepy in the daytime. But in the absence of light, you will understand that it is much more pleasant and easier for you to look at such a screen!

Turn on the convenient activation of the Light Filter

It is long and inconvenient to turn on the filter in the Settings every time. Let's configure activation by triple pressing of the Home key.

1. We open Settings -\u003e General -\u003e Accessibility.

2. Looking for an item Keyboard shortcut, choose Light filters.

Now, to turn on the filter, just press the Home key three times and select the item Light filters.

Use this function at night. Your eyes will definitely thank you.

P.S .: owners of Apple's newest tablet are in a better position. The 9.7 ”iPad Pro features a screen that automatically adjusts to the optimal white balance based on lighting conditions.

The basics

You can choose from the Apple collection of wallpapers or Dynamic wallpapers that move slowly in the background. Also you can choose a photo from your photos.

Once you find a wallpaper that suits you, tap it to open a preview of the lock screen wallpaper. Here you can see how your wallpaper will look and also specify whether you want to set it as your universal wallpaper, or just on the lock screen or only on the Home screen.

How to free up space on iPad

Your iPad may no longer allow you to take another photo. He may be refusing to download another app. Since iOS storage space isn't expanding, it's important to keep an eye on what is consuming the available gigabytes on your device. Here's how to do it.

Go to section "General" -\u003e "Storage & iCloud" -\u003e "Manage" in section "Storage" and wait a minute or two as iOS calculates which apps are using most of the space inside itself and in iCloud.

Most often Music and A photo and Camera are the two worst consumers. If you use a service like Apple Music or Spotify, you can safely delete the music cache on your device to free up space. If you create backups photos and videos on your PC or Mac, you can delete them as well.

Further down the list, you will see the programs you use, starting with the most used. If programs you rarely use take up a lot of space, tap on them and then tap "Uninstall a program" to uninstall it in an instant.

Set up location-based reminders for specific locations

If you want to be reminded to do something when you leave your home, work, current location, or any address from your address book, it's pretty easy to set up using the app. reminders in iOS. But what if you want to remember to buy something when you go to the store? You probably don't want to add store addresses to your address book in order to use this feature.

Fortunately, you don't need this. When you create a reminder, tap it and turn on Remind Me at Location. By default, reminders will populate your current address - tap it and a variety of options will appear, including at the bottom, a text box for entering a custom address.

Make your iPad read to you

Enabling the option "Speech" allows your iPad to read any selected text aloud. Open up "Settings" -\u003e "General" -\u003e "Accessibility"... Scroll down to Speech and tap to turn it on. You can also adjust the speaking speed, choose from a wide range of voices and highlight words as you speak.

Now go to any application that will allow you to select text. It could be post office, and Safari, Notes and many others. Select the text and the context menu will show new parameter (you may need to press the right arrow to view extra options). Click the "Speak" command, and your iOS device will start reading the text aloud.

Enable Emoji Keyboard on iPad: Access Special Emoticons and Animal Icons

Emoji Keyboard lets you insert all sorts of fun images wherever you can type, including recent additions of tacos, unicorns and you know emoji and middle finger. Your iOS device can also speak the names of these characters.

You may have seen these iconographic symbols in e-mails, iMesseges and tweets, and wondered how people were able to print them. You may have mistakenly thought that you need to download a third party application in order to access these special characters.

Not. Apple provides these characters, called Emoji, as an international keyboard. Open up "Settings" -\u003e "General" -\u003e "Keyboards" and select Keyboards... Then press "New keyboards ..." and find Emoji... Now open the application where you can enter text.

How to work with multiple tasks at the same time on iPad

Now, this tip only applies to those using a fairly recent iPad version, and by recent we mean iPad mini 2 or newer, iPad Air or the next versions, and of course the iPad Pro. The multi-tasking functions are divided into three groups. Image alignment, image splitting and picture-in-picture. All iPads mentioned can use image alignment, which opens up a small sidebar (using 1/3 of the screen) displaying an iPhone-like app alongside the former. You can then change the program by swiping from the top of the program and selecting a new one.

The only drawback is that you cannot interact with both applications at the same time, and if you want to use the application you originally opened, you first need to close the image fusion application.

Image splitting is more impressive, but only available on iPad Air 2, iPad mini 4, and iPad Pro. With image registration, users can "pull" a program into split screen mode, where both programs can be used at the same time, and the amount of space can be adjusted by pressing and holding the divider between apps.

Finally, picture-in-picture mode allows users of recent iPad versions Watch a video or talk to a camera in FaceTime while using other apps. When in a FaceTime call or watching a movie (not just Video - some third-party apps are supported) just press the Home button and the video will be minimized and displayed in the bottom corner of your iPad. You can safely drag it to other corners of the screen, if necessary, and when you click on the video, it will expand to full screen.

Push up

You won't believe how much time you can save. If you've flipped half a webpage in Safari, tap the top of the screen ( to the clock display area) to return to the top of the page. Try it in other apps as well - many of them, including third-party apps, use this navigation trick.

Volume key shooting

Did you know you can take photos with any volume button? Their position is much more convenient when shooting in landscape mode, especially when using an iPad.

Siri

When you press and hold the Home button on iPad, you'll see a "\u003e" icon to the right of the primary Siri button. Click on it and you will see a menu of all the different inputs your iPhone can use. Choose the one you want.

Your own IMDb

You probably already know that you can use Siri not only to get information about what's happening in theaters near you, but also Siri is an expert in almost every movie.

Not only can you ask something about your favorite movies, but you can also get Siri to do some serious work. For example, if you are curious about which actors have appeared in films together. You may ask, "What films do both Susan Sarandon and Tim Curry play in?" And Siri will answer: "The Rocky Horror Show" and "Toddlers in Paris." Hmm, how interesting.

Camera

Now for some tips on camera and photography.

How to make panoramic photos better

What's the secret to a well-made panorama? A few simple guidelines will help you create something memorable. Above all, avoid wobbly or crooked lines by sticking to the center line: this is the main and most important point.

Also consider the composition before you start photographing and turning. Decide where you stop (remember any ugly places you want to leave out of the frame) and think about lighting: Panorama mode, which includes well-lit and dark areas, may not work very well. Trying to take panoramic shots in dark light will never succeed.

Finally, work (and move) slowly throughout your shot to keep it neat.

Reverse panorama

While we're on the subject of panoramic photography, we'll give you one more tip. Typically, the Camera application prompts you to take panoramic photos from left to right. But Apple hasn't made it clear that the arrow could be canceled altogether. To flip the arrow and allow you to take a panoramic photo from right to left, simply tap once on the panorama overview paneto flip it over to the opposite side of the screen.

Shared Albums

You probably already know about iCloud Photo Library, which shares images between your iOS devices (and Mac). But if you want to share photos with specific friends, family or colleagues, you can also create shared photo streams.

To create such a flow, open "A photo" and tap the General tab on the toolbar. In the upper left corner there is a "+" button. Tap it and enter a name for the shared album and a list of people you want to invite.

How to remove red eyes from iPad photos

The built-in red-eye removal tool can help you sort out some of the most common photography problems, although iPad photographers are less likely to experience this problem due to the lack of a flash on the iPad. Either way, find some imperfect photo in Photo Stream and click Edit (in the upper right corner), then select the red eye option in the upper left corner: a red circle with a diagonal white line.

It's worth noting that this icon only appears if iOS detects red eyes in a photo, which is both impressive and really annoying, especially if iOS doesn't detect red eyes where they are present.

Settings

How to improve storage on iPad

You don't necessarily need your personal information to be available to every application that requires it. iOS can give you the kind of micro-control you need in this situation. In the Privacy section of Settings, you can not only configure which applications have access to your location, but also prevent them from accessing your contacts, calendars, reminders, photos, and Bluetooth sharing.

Also, if you use Twitter or Facebook, you can decide which of your apps can log in with your credentials. Just tap the appropriate section for any of them and slide the switch for the selected application to the OFF position.

How to set restrictions

Open up "Settings" -\u003e "General" -\u003e "Restrictions", click "Enable Restrictions" and you will be prompted for a password. Then you can choose which features you want to block on your iOS device. If you plan on handing over your iPhone to one of your kids who has a habit of accidentally deleting your apps, you can specifically disable this feature from the Restrictions screen. You can also deny access to iTunes Store, iBook Store, Safari, Camera, FaceTime, and more.

Setting up Guided Access on iPad

While we are talking about what can limit your iOS device, it's time to mention the "Guided Access", which you enable in the section "Basic" -\u003e "Accessibility"... Once you have enabled this feature, go to any other application and press the Home button three times. This enters the device into Guided Access mode.

Now, if you want, you can close certain areas of the interface of the current application. Let's say, for example, that the game your child will be playing has the ubiquitous settings button. You can draw a circle around this button, and this part of the application will ignore any presses.

Other key feature The access guide is that it disables the Home button so your child won't be able to accidentally exit the app. To exit the application in Guided Access mode, again press the Home button three times and enter your password.

One of the added benefits of Guided Access is that it can serve as a the best option Do Not Disturb as it turns off notifications and alert sounds.

How to limit ad tracking

If you're going to restrict your kids' access, you can also restrict what advertisers can do. In section "Settings" click "Confidentiality"then click on "Advertising"squeezing down. On the screen that appears, you will find two options. The first, Limit Ad Tracking, is an indicator for online advertisers that you don't want them to track which advertisements you viewed and which ones you were interested in (what they are doing so that they can show you ads that they think might be better for you).

The second option on this screen is a button to reset your ad ID, which is meant to be an anonymous tracker that advertisers can use to find out your interests by displaying their ads in apps. If you notice that the ads in the app seem to know you too well, you can reset your ID here to reset your identity.

How to set up a double-click on the Home button

On the menu "Universal access" in "Settings" -\u003e "General" there is an option to choose how quickly you need to press the Home button twice or thrice so that the press counts as a single action, rather than separate taps. Just click on the Home subsection and choose your preference - Default, Slow or Very Slow.

How to assign a function when pressing the Home button three times

The Triple-Press Home Button option now allows you to select one action (Switch Control, VoiceOver, Invert Color, Increase, Color Tone, or Assistive Touch) or multiple options to be displayed in the menu when pressed three times.

Safari

How to quickly access your recent browsing history in Safari

Press and hold the Back button in Safari to view a list of your recently visited pages, and press and hold the New Tab (+) button to get a list of recently closed tabs... If that's not enough and you need to view your entire browsing history, click the Bookmarks icon (book to the left of the URL field) and select History.

How to open new tabs in the background in Safari

Safari on Mac makes it easy to open linked web pages in a new tab, so you don't have to interrupt what you're reading, simply because you also want to check multiple linked items. You get the same bonus on iOS, although you need to enable it first.

An informative article for those who are tired of listening: "O May bastard, do not read from the iPad, it is harmful!"

Man is a terribly dogmatic and gullible creature. Tell him that combining pills and alcohol is extremely harmful, and he will not allow himself to take pain relievers after a glass of wine, even if his head is splitting. But this person will not be able to explain what exactly is harmful to drink pills with alcohol, because he was never interested in this. Monitors emit - dogma. What do they emit? There is no answer or, what happens more often and even worse, people begin to carry nonsense, heard somewhere on the occasion. Let's keep putting cacti next to system unit, buy nano-capsules and shorts. Cacti protect from radiation - also a dogma. And there are very, very many such dogmas, you probably come across them.

Another mega-dogma sounds like this: "reading from the screen is harmful." Why? Have you thought about this? Have you studied the issue, consulted an ophthalmologist? But another grows out of it: “reading from an e-book is useful”. Yeah, hair grows thicker, abs sway itself, antioxidants are produced. Ok, even if “reading from an e-book is not harmful, like from a screen” - this is also a dogma and also nonsense. Let's talk about this.

People hardly try to explain this phenomenon of "harmful screen reading". It has already been absorbed into the bloodstream along with a mysterious destructive radiation, from which children and pets must be kept away. On the Internet, to the question "is it harmful to read from the monitor" the general answers: "yes", "of course", "you are still asking", but no specifics. "Are you crazy to buy

iPad? It is harmful to read from the screen, buy a reader! "- a typical opinion. In the Russian Internet you will not find an ophthalmologist professionally versed in the matter in general during the day with fire.

Why do I consider this nonsense and such an opinion was formed? Let's take a look at the situation. I would very much like to destroy this myth.

The first factor: flickering of the picture on the monitor.

Even in the days of huge CRT monitors, when this myth was born, and when people en masse placed cacti next to computers "to save them from radiation", everything was ambiguous. The problem arose from the incompetence of users. The fact is that by default, in the era of the beginning of the mass distribution of computers, a frame scan of 60 hertz was set on monitors. That is, 60 times per second, the beam passed through the phosphor of the screen, redrawing the image. Human eye and the brain is able to see much more than 24 frames per second (another myth about 24 frames and 25 frames, by the way, and if you believe in it, it is better to drink alcohol and a pill right away). This flickering caused a headache during prolonged work in front of the monitor.

It was necessary to set a higher frame rate - 85 Hz, 100 Hz, 120 Hz or even more, if the monitor allowed. At such a scanning frequency, flicker is not visible (vision does have a certain inertia), and the problem is solved. At least part of it, because this is only the first factor in eye fatigue.

For LCD monitors, by default, the "frame scan" frequency is also set to 60 Hz in the driver settings, and most likely you are now reading this text on the monitor, to which the video card (like the old CRT brothers) transmits a picture with a refresh rate of 60 times per second ... But there is a difference - as such, LCD monitors do not have a frame scan, because the LCD screen works "in the light". There is a matrix of crystals that work like doors (to put it in a big simplification). There is always a light behind (matrix illumination lamps), and if the "door is open", we see a glowing pixel. If closed - not luminous. "Imagine an LCD monitor as a house with burning windows, it will be even easier. There are curtains, curtains and partially curtains in the house. These are those pixels.

All updating of the image on the LCD monitor occurs by alternately opening and closing these "doors" or "curtains" at a certain angle. The light always remains the same. This is why LCD monitors have a black screen in the dark. In monitors and TVs with dynamic contrast, the brightness of the backlight lamps, as well as their arrays, can vary in a wide range, but in any case, they have no rays from the Electron Ray Tube that ignite the instantly extinguishing phosphor. [technically speaking, backlight lamps may flicker in the monitor with a certain frequency, but this is a completely different question and a completely different frequency, any noticeable flickering was found only on low-quality displays]

Plasma TVs, by the way, also flicker. This can be easily seen by looking "over" the screen of such a TV - peripheral vision detects flicker better. [It is the peripheral vision that can be contrived to see the flickering of CRT monitors and fluorescent lamps, as well as the flickering of incandescent lamps in homes where there are problems with electricity.]

Second factor: flickering ceiling lamps.

Fluorescent lamps, which are most often installed in offices, contributed to the fatigue of vision - they also flicker at a frequency of about 100 Hz. Unlike them, good old incandescent lamps do not flicker (or rather, they flicker wrong) - the inertia of the incandescent filament, which does not cool down instantly, affects.

The third factor: the office environment - air conditioners.

When reading, a person concentrates in any case, with a book or a monitor. The frequency of blinking decreases, as a result, the cornea of \u200b\u200bthe eye dries up. Since few of the users control this process (often you need to force yourself to blink), the very fatigue of the eyes occurs - dryness, the effect of "sand in the eyes". In the office, this problem is aggravated by the use of air conditioners, which, in addition to cooling, that is, their main function, also produce air dehumidification. The pattern is clear - even drier air - we blink less often - our eyes get even more tired. Humidifiers are generally useful stuff, think about it.

The fourth factor: the brightness of the monitor needs to be adjusted.

Looking at the monitor is no more harmful than looking at the mountains, your beloved kitten or a piece of sausage in the fridge. Watching is not harmful at all. What is really harmful is looking at a monitor that is too dim or too bright. And not every computer user guesses to adjust the brightness correctly, as before with a frame scan. Moreover, the comfortable brightness of the display is very dependent on the environment - it will be one in a brightly lit room, the other if there is a pair of incandescent lamps from the light in the room, and the third if you are working next to an open window. The average comfortable monitor brightness is about 120 cd / m2.

The fifth factor: the ergonomics of the workplace, and more specifically, its lighting.

It is not so much harmful for the eyes to look at the bright as to fall into sharp changes between bright and dark. What do most users do most often? Shifts your gaze from the screen to the keyboard! Is it well lit with you? Is there an individual lamp on the table? Moreover, workplaces are often completely incorrectly lit, and this difference in brightness just ruins his vision, as it ruins him reading a book with a flashlight under a blanket.

So these are the main five factors. Now about e-books. Their popularized "main advantage" is "the screen is like paper", that is, it means that it does not have self-illumination. A person builds a chain of conclusions from this factor: like paper -\u003e does not light up -\u003e not a screen -\u003e not harmful. This is bad logic. You are not guided, looking at wolf berries, by the logic that they are “red and round -\u003e like currants -\u003e not harmful? Here is the same case. And then, reading books, no one spoiled his eyes.

Reading from paper also requires the ergonomics of the "workplace" - the correct distance from the book to the face, the correct lighting of the book. I don’t know how it is now, but before it was even in schools, in the elementary grades, we were going through how to sit properly, how to properly light.

Books are read in reflected light, the screen itself emits light

There is another myth - "books are read in reflected light, and the screen radiates." Say, "for thousands and thousands of years, people have become accustomed to reading in reflected light." Uh-huh. And tell me, how exactly does the reflected light differ from the emitted one? The second question is that the backlight lamps in conventional monitors are located on the side, they shine on a reflective substrate, which pushes through LCD crystals with reflected light. Is that reflected light enough for you? What is the difference between the light of a flashlight (or the sun) directed at a sheet of paper and a flashlight of a monitor backlight? What is the difference between the light reflected from the scattering part of the LED bulb from the sunlight reflected from the table?

[And by the way, people DO NOT read for thousands and thousands of years. The history of humanity, printing, literacy and the availability of books for the average person to help you is worth studying.]

Ok, next moment. Let's remember the classic rules of reading books.

Reading in bad light - you need to use a floor lamp
. Reading in the bright sun - a huge difference in brightness is harmful to the eyes
. Reading in public transport - the vibration of a book is harmful, plus there is bad light in transport, in principle
. To read while holding the book too far or too close from the eyes - it is considered a comfortable distance of 30-35 centimeters, which is equal to the length of the arm from the elbow to the fingers

With regard to reading from the screen, I would add an item - do not read from a screen that is too bright or too dim. Use the correct font size. Do not read from black - you immediately create a huge difference in brightness with light letters on a black background (this is why sites like

oper... ru and dpreview. com I read in browsers that can change the page design to the usual black and white).

Unconfigured monitor, or screen

iPad with excessive brightness, I am ready to compare with a paper screen, on which they shine not with a floor lamp, but with a searchlight. Try to read a book under such conditions and your eyesight will be just as tired. But books on electronic paper, just like tablets and laptops, are most often read in conditions that do not correspond to ideal ones - under poor light, in transport. And the eyes deteriorate from this no less, and in some cases, even more.

I would even put the question like this - imagine that you have a choice: read a book in poor lighting or read a book in poor lighting, directing a dimmable flashlight at the screen. Which option would you prefer? By the version with a flashlight, I mean a device with a self-luminous screen, the same

iPad, eg.

That is why "useful" reading with

e- ink - just a replicated myth that has nothing to do with reality. For many years I have been reading from all available sources - paper, computer screen, laptop, monitor, now fromiPad and phone. And first of all, I think about ensuring that the source of the text is configured correctly, whether we are talking about a floor lamp next to an armchair when reading paper, or about the brightness of the screen and the color of the background when reading from a monitor. When your working day, for the most part, consists of reading and writing text, you have to think about your health.

So why are readers better?

Ok, so that it does not look like fanatical screams of a person who prefers to read from the screen rather than from the reader, I will explain what I like about readers.

First of all, they work for a long time. Charging your device once a week is more enjoyable than charging it every day.

The second factor is that the reader's screen is not entirely white, it is really comfortable to read it on vacation, lying on the beach. More comfortable, by the way, than a paper book. It does not fade in the sun and does not catch the glare of ceiling lamps. I cannot force myself not to read, even knowing that reading in the sun is harmful. Therefore, it is on vacation that I prefer to take a reader. By the way, due to the light gray screen, which reflects light well, the reader heats up much less in the sun. Laptops and tablets, under the same conditions, quickly overheat. Light gray and white - to a lesser extent.

Readers are thin and light - much lighter than tablets and normal paper books.

Readers are cheap - yes, their price even in Russia is much less than that of any tablets. it available device, which also allows you to save a lot of money on literature. And e-books (tracts) do not take up space on the shelves as much as paper literature.

Than readers are worse

If we compare readers with tablets, then their main drawback is that readers are suitable only for fiction. Read formats from themPDF andDJVU, technical literature, tutorials with illustrations and everything where there is graphics is impossible. Or at least terribly uncomfortable. Since I read not only stories, but also a lot of documents, a tablet, and specificallyApple iPad, a more suitable solution for me. And of course, the reader is not designed for movies, music, games, surfing the Internet, blogging and business applications.It is read only.

Taken

Sometimes you get up from the computer and feel squeezed out like a lemon. Didn't seem to be doing anything supernatural, but tired. The eyes were especially tired. You make a promise to yourself to spend less time at a laptop / iPad, but then you realize that there are a lot of things to do and to do all of them you need to spend even more time at the computer than before ... Do you know this feeling?

2 years ago on my old laptop the settings went wrong and I worked for half a year behind an incorrectly configured screen. As a result, my vision was very bad.

I managed to restore my vision during a retreat in a meditation center, where I did not use any electronic devices in a week. After 7 days of constant meditation and fasting in the mountains, my normal vision returned to me again. And now I clearly see how it improves when I spend time in nature, admiring the beauty of the Earth, and not the screen of a tablet ... But I do not want to exclude a phone, tablet and laptop from my life, out of 24 hours in a day - 10 am I spend, staring at the screen: I work, I read, I look for ideas for knitting, I watch movies or TV shows, I talk to my parents, I write texts, etc.

I try to be in nature as often as possible and do exercises for my eyes. It really helps! That's why when the developers sent us an email telling us about their new app for training eyes, I downloaded it right away.

Not that I was hooked on the design or the exercises themselves - they have been known for a long time, they are both on the Internet and in different books. In addition, there are grammatical errors in the texts in the appendix:

But I really liked that a cool robot shows the exercises. And doing exercises with someone (even if this someone is just a robot) is much more fun:

By the way, the exercise of palming is very useful if you want to master speed reading. And I also imagine that my favorite book and serial heroes are doing the exercises with me - you’ll laugh at all. Try it. :)

There is information on how to do the exercises correctly:

And the most useful thing: you can turn on notifications in the settings so as not to forget to do these same exercises:

True, a positive mood - the best way restore vision, checked!

I will share an exercise that I came up with for our future iPad application with Decafe “365 Ways to Catch Inspiration, or How to Shake It Up and Feel the Joy of Life” (I hope we will finish it by the end of the year):

Eye Charger:

Draw a simple 3 by 3 chart. Fill it in with words (or wishes) that are important to you. Leave the center of the table blank.

Here's what I got, for example:

Every half hour (start a timer on your phone or computer to be sure), distract from what you are doing and do eye exercises. To do this, imagine that you are a small dot and are in the center of the table.

You will no longer need the drawn table, just remember what words you have placed in it. You need to work with an imaginary table.

You lift your eyes up and see your upper word (more precisely, the image that corresponds to it), touch to the right and see another word, look at the lower left corner and ...

Is the principle clear? It is important not only to see the word, but to feel it, to connect to the image.

Gradually add other movements: for example, circular, trying to see-feel all the words from the table. First clockwise, then counterclockwise. Then add left-right movements by combining the two matching words, as well as diagonally and crosswise. Create your own trajectory for the movement of the eyes, combining images into a coherent whole.

And visualization is also useful for eyes. :)
