An article posted by Medical News Today reveals that specific vitamins are critical for maintaining healthy eyes and preventing the development of certain eye conditions: https://www.medicalnewstoday.com/articles/326758.php#vitamins

Four important vitamins for proper eye functioning are Vitamin A, Vitamin E, Vitamin C, and B Vitamins, and deficiencies in these vitamins may progress eye disorders. Vitamin A deficiency has been linked to night blindness, and an increase in B vitamins may reduce the risk of age-related macular degeneration (a degenerative eye disease that impacts vision). Additionally, both Vitamin E and C deficiencies have been suggested to lead the development of cataracts.
According to an article published in PLOS (Public Library of Science) Medicine, 90% of world’s blind population lives in poor countries, and people afflicted with visual impairment due to cataracts were poorer than those with normal vision. This is especially significant because individuals living in poverty are more likely to lack necessary vitamins in their diets and be more at risk for conditions related to vitamin deficiencies.
It is important that we receive the proper vitamins through our diet and supplementation in order to prevent the development of eye conditions.
