If you're one of the millions of Americans who spends eight to twelve hours every day staring into a computer screen, take note: You may need more lutein. Recent research from the British Journal of Nutrition showed that lutein, an antioxidant carotenoid in green leafy vegetables and winter squash, may protect eyes from damage associated with long-term computer use. In the study, individuals taking 12 mg lutein per day for 12 weeks showed improved visual performance. Other studies have linked lutein to a reduced risk of age-related macular degeneration, one of the leading causes of blindness in people over age 60. For the best results, take a combination of lutein and zeaxanthin (another eye-healthy carotenoid) per day with food. And try other eye-benefiting supplements below.
