Answer 2

Explanation:

1. Vitamin A

Vitamin A plays a crucial role in vision by maintaining a clear cornea, which is the outside covering of your eye.

This vitamin is also a component of rhodopsin, a protein in your eyes that allows you to see in low light conditions

Vitamin A deficiency is rare in developed countries, but if unaddressed can lead to a serious condition called xerophthalmia.

Xerophthalmia is a progressive eye disease which begins with night blindness. If vitamin A deficiency continues, your tear ducts and eyes can dry out. Eventually, your cornea softens, resulting in irreversible blindness

Vitamin A may also help protect against other eye afflictions. Some studies suggest that diets high in vitamin A may be associated with a reduced risk of cataracts and age-related macular degeneration (AMD)

For general eye health, vitamin-A-rich foods are recommended over supplements. Sweet potatoes are an excellent source, as are leafy green vegetables, pumpkins and bell peppers

Note: Severe vitamin A deficiency can lead to xerophthalmia, a serious condition that can result in blindness. In some studies, high amounts of vitamin A intake were associated with a reduced risk of cataracts and age-related macular degeneration.
