Vitamin A is directly related to photosensitivity and is a nutrient directly related to vision. B- carotene can also be converted into vitamin A in the body. Vitamin B group (especially vitamin B 1, B 12) is closely related to nerve health (including optic nerve), and lack of it can easily lead to neuritis and neuropathy. Therefore, vitamin B group can not be lacking. Free radicals, which have been widely discussed recently, can also cause damage to eyeball and optic nerve, so the nutrients (B- carotene, vitamin C, E, B2 and selenium in minerals) that help to catch free radicals have indirect effects on eye protection. 1.
