Lutein May Help Eyes (Computer Use)
I take a Lutein supplement nearly everyday for eye health and avoiding age-related eye conditions such as macular degeneration. Currently I'm using Natural Factors 20mg softgels (FloraGLO). Here's a short article fron Energy Times about computer use and Lutein.

Lutein May Help Eyes
Cope with Computer Use
APRIL 2009 - All you squinting, blinking computer users, take heart. Lutein, a nutrient used to reduce risk of an age-related eye disorder, may help people of all ages who log a lot of screen time.
Scientists from Peking University assigned 37 volunteers between the ages of 22 and 30 to either one of two lutein groups (6 and 12 mg a day) or a placebo (lookalike) group for 12 weeks. �Visual function in healthy subjects who receive the lutein supplement improved, especially in contrast sensitivity, suggesting that a higher intake of lutein may have beneficial effects on visual performance,� wrote the researchers in the 2/19/09 online edition of British Journal of Nutrition.
Lutein, a carotenoid found in green leafy vegetables and egg yolks, is concentrated in the retina at the back of the eye and particularly in a spot called the macula responsible for sharp central vision. Along with its sister compound zeaxanthin, lutein is thought to provide protection against cell-damaging molecules called free radicals that occur when the retina is exposed to sunlight.
The rich supply of lutein in the macula has led many scientists to believe that this nutrient may help lower the risk of age-related macular degeneration (ARMD), a disorder which causes loss of central vision. ARMD is the leading cause of blindness in Americans age 65 and older.
