Eye vitamins: Can they prevent or treat glaucoma?

Probably not. Several dietary supplements are marketed as eye vitamins. But little evidence supports using these products for preventing glaucoma or reversing vision loss due to glaucoma.

Few clinical trials of eye vitamins or supplements for glaucoma have been conducted. One study showed that taking folic acid may reduce the risk of some types of glaucoma. Another showed that vitamin C may decrease the chance of getting glaucoma. More research is needed to understand the possible role of vitamins or supplements in preventing or treating glaucoma.

If you're interested in trying eye vitamins or supplements, discuss the benefits and risks with your eye doctor.
