Citrus fruits

The vitamin supports healthy blood vessels in your eyes and is found mainly in fresh fruits and vegetables. Along with other vitamins and nutrients, it can help prevent the development of cataracts and age-related macular degeneration.

Citrus fruits, such as oranges, lemons, and grapefruit, are rich in vitamin C, an antioxidant that works directly to protect the body's cells from free radical damage. This antioxidant protects the cells in your eyes from oxidative stress, which promotes the development of vision-threatening conditions including macular degeneration and cataracts. Vitamin C has been shown to be essential for the function of cells inside the retina, the structure at the back of the eye that senses light and converts it into electrical signals sent through the optic nerve to the brain to create the images you see. This helps in scrounging harmful free radicals from your body and preventing cell damage.
