1. Cataracts: Vitamins C and E and proper sunglasses that block 95% of UVA and UVB can help. Most people with cataracts initially just need a new prescription for glasses. Contrary to popular belief, the majority of people do not require cataract surgery because in the long run, they will not cause significant vision loss.
2. Glaucoma: Walking briskly for 20 min, 4 times a week, can often help lower your eye pressure significantly. Vigilant monitoring of your eye pressure, field of vision, and thorough eye examinations can prevent blindness from the damages caused by glaucoma.
3. Macular Degeneration: Protection from UV rays with sunglasses and daily supplements of vitamin C, beta-carotene, vitamin E and zinc oxide with copper is recommended for most people.
