Ipad = Eyestrain

The much awaited ipad is out this weekend. There has been lavish praise for it. The Wall Street Journal reports that experts are now debating which e-reader device is easier on the eyes.
While some e-readers provide printed book-like black text on a white background, others use a computer-like color screen that is backlit and uses a liquid crystal display. Although the choice of an e-reader may come down to personal preference, one eye expert maintains that all of the devices, no matter what their technology, may cause eyestrain. The solution to that, he recommends, is for people using the devices to take frequent breaks to rest their eyes.

Some people can have trouble with an e-paper screen, like the Kindle, where text looks like a dark shade of gray on top of a light shade of gray, says Mary Lou Jackson, director of vision rehabilitation at Harvard's Massachusetts Eye and Ear Infirmary. For those people, Dr. Jackson says "hands down I would vote for the iPad."
