Don't watch TV or computer for a long time. Pay attention to rest your eyes. Eat more grapes, spinach, tomatoes, cod liver oil, yeast, green leafy vegetables, egg yolk and milk. These foods are rich in vitamins A, B 1, B2 and calcium, which are very helpful for eye health. Increase protein in the diet, eat less candy and high-sugar foods, and eat more carrots, bean sprouts and calcium.
