eye strain after reading on the iPad

Wow, this problem describes my experience to a "T". Using the iPad literally wigs out my eyes. Spending an hour on my iPad will mess my eyes up so dramatically that I can't focus normally for about 24 hours.

I live on computers. I've never experienced this problem before and it is definitely iPad-induced. No problems with my droid phone or kindle or any number of PCs I use throughout the day.

I adjusted brightness, which helps. It's the pattern of 1-hr use and then 24-hour recovery that prevents me from really enjoying the wonderful features of the iPad. I'm hoping that others write about their experiences so we can discover how big a problem this is. My friend uses the iPad without any eye issues whatsoever. I know this original comment was written a while ago, so maybe many have no problems at all.

There are two things I do to make reading on the iPad 2 a pleasant experience:

1) I applied an anti-glare film on the screen to reduce reflections when reading in daylight. I used a good quality one (Steinheil Optical, but I'm sure there are other good ones), that didn't lessen the iPad's clarity and brightness, at the same time removing my own face from the screen I'm staring at. (Then, it gives the screen some paper-like coarsness, that I enjoy more than the plain sleek glass).

2) Use ambient light when reading in the evening/night. We often believe that the light emitted by an LCD screen is enough for our eyes, but this is wrong; our eyes need indirect light, more than mesmerizing in-face light. Turning a lamp on next to you will let you turn the iPad's brightness down, reducing in-face light.

I could add that I turn wifi off, and this helps with the general suppression of disturbing phenomena (no headhache when the waves are off).

I cannot do a comparison with an e-ink device, but I can say that the reading experience is fine for me (sometimes reading a couple hours with no break).
