Mobile devices trigger eye strain

"For decades, optometrists have recognized that spending long hours in front of a desktop computer can lead to a range of eye-related problems. Now, hand-helds - with screens barely larger than a postage stamp - are triggering a fresh round of complaints. WSJ reports on how tech companies are addressing studying the science of "readability" -- and looking for ways to make hand-held computing easier on the eyes.

-- Microsoft Corp. has adapted a line of fonts specifically for hand-held screens, such as "Frutiger Linotype"

-- Microsoft has also developed a technology called ClearType, which helps smooth the jagged edges of letters on the screen and increases the sharpness of text displays.

-- Sony Corp. are looking for ways to make reading off the small screen more like reading from paper.

-- Many gadget makers, including Palm Inc., offer "transflective" screens that have a backlight for low-light situations, but also have the capacity to reflect natural light.

... The best remedy for hand-held-related eyestrain is to take frequent breaks, and avoid using the gadgets for long periods. Elise Brisco, an optometrist in Los Angeles, recommends looking away from the screen, and into the distance for about 20 seconds every 20 minutes to give the eyes a rest."
