iPad, iBad!

[Ruvaida]

Hello,
I've been using iPad for around a year a half and so. But in 2012 I started using it really heavily, and this has been the worst year for my eyes ever.

So does ipad screen cause more strain to the eye compared to the normal PC monitor (LCD or LED)?
I know the small size of the ipad matters, and also the fact the we draw it close to our faces compared the PC monitor which is almost 1 foot away from our eyes.
But I mean in terms of the radiation it produces, it it equal or less, more than the usual monitor? Or are there any other factors that will make ipad bad for dry eyes compared to PC monitors?

Anything to share on this?

Hi

See below: The iPad screen is typical of a "high end" desktop or laptop LED screen. You can manually adjust the brightness of your iPad display, which can help. See also below for directions.

A likely possibility is your blink rate. Be sure to be mindful of your eyes and the need to blink regularly while viewing your iPad screen. Many studies note that with computer use, we tend to blink less. And blinking is very important for people with dry eye.

I have both an iPad and a Kindle. I love the iPad for most things, but NOT for reading books. The softer screen brightness of the Kindle is much easier on the eyes than the iPad. The back-lit LED screen of computers and tablets, even at the dimmest setting is much more harsh than the Kindle eInk. At least that is my experience.

Change screen brightness on your iPad

By default, your iPad will automatically adjust its brightness thanks to a setting called Auto-Brightness (which can be turned off). Whether or not it is enabled, you can always manually dim the screen (lower brightness, well suited for reading in bed, for example), or make it brighter (ideal in a direct sunlight situation, which makes the iPad's screen harder to see). This tutorial explains how to manually decrease or increase the brightness of the display on your iPad, depending on where you are using it.

MANUALLY MAKE YOUR IPAD SCREEN BRIGHTER OR DIMMER

Follow these steps to change your screen brightness:

• Click on the "Home" button to return to one of your Home screens.

• Then, flick through (left or right) until you see the "Settings" icon, and tap on it.

• When the iPad Settings screen opens, tap on the "Brightness and Wallpaper" category on the left.

• Once you are looking at this screen, you will see a slider with a "sun" icon on either side.

• To decrease your display brightness to the minimum, move the slider all the way to the left; to further to the left you go, the dimmer the screen becomes - and your iPad gives you a real time preview of the setting, so you'll know when you have reached the ideal brightness.

• And moving the brightness slider to the right makes the display brighter, which will often be necessary in bright sunlight or outdoors in general - the technology used for the iPad's screen is the same as high end desktop and laptop displays (LED backlit with IPS technology - which explains the very wide viewing angle you get from your iPad) - a very unusual combination of crispness and brightness for such a small device.

• Once you have found the brightness you wanted, just click on the Home button to return to exit the iPad settings.
This is how you change the brightness of your iPad's screen using the global settings - some applications (like iBooks or the Kindle application for iPad) let you change the display brightness from the app itself, which spares you from having to stop what you are currently doing to go make your display brighter or dimmer. Keep in mind that a brighter display runs down your battery faster.

Tip: if you notice that your iPad increases or decreases the brightness of its display without your intervention, it means that the Auto-Brightness setting is turned on (it is by default). Learn how you can temporarily disable Auto-Brightness on your iPad (and re-enable it manually later on).
