Zinc transports vitamin A to the retina to produce melanin. Meat, shellfish, legumes, and nuts are rich sources. A deficiency can cause night blindness and poor retinal function. Long-term low zinc may contribute to AMD and slow healing. Proper intake ensures eyes receive vital nutrients efficiently. Zinc also supports enzyme function in the retina, helping maintain clear vision. It boosts overall eye immunity and repair mechanisms.

9. Selenium

Symptoms of Deficiency: Cloudy vision, eye fatigue, and higher oxidative stress in eye tissues may appear.

Selenium acts as an antioxidant and protects the lens from oxidative damage. Brazil nuts, seafood, and eggs provide selenium. Low selenium levels can raise cataract and retinal degeneration risks. Selenium also enhances the effect of other antioxidants like vitamin E. Adequate intake helps maintain lens clarity and eye strength. It is on this list of best eye vitamins as it reduces inflammation and protects delicate retinal cells. Selenium also supports eye tissue repair after oxidative stress.

10. Beta-Carotene

Symptoms of Deficiency: Dry eyes, poor low-light vision, and increased eye irritation can occur.

Beta-carotene converts into vitamin A in the body. Carrots, pumpkins, and sweet potatoes are excellent sources. Lack of beta-carotene may cause dry eyes and poor night vision. It also supports overall retinal health. Including these foods regularly strengthens vision and eye resilience. Beta-carotene also protects the cornea from oxidative damage. Adequate intake maintains healthy adaptation to low-light conditions.

11. Vitamin B1 (Thiamine)

Symptoms of Deficiency: Blurred vision, eye fatigue, and weak eye coordination may develop.

Thiamine supports nerve function, including the optic nerve. Whole grains, beans, and nuts are rich sources. Low thiamine may lead to blurred vision and eye fatigue. It helps the eyes communicate effectively with the brain. Maintaining adequate intake preserves visual performance. Thiamine also protects against optic nerve damage from chronic stress or poor nutrition. It supports eye muscles and coordination.

12. Vitamin B2 (Riboflavin)

Symptoms of Deficiency: Light sensitivity, burning eyes, and vision strain are common symptoms.

Riboflavin reduces oxidative stress in the lens and prevents cataracts. Milk, eggs, almonds, and leafy greens are good sources. It is one of the best eye vitamins as its deficiency increases lens clouding. Riboflavin also protects cells from light-induced damage. Including it supports long-term eye clarity and comfort. It improves the eyes’ ability to process light and color. Riboflavin also helps prevent dryness and irritation in the cornea.

13. Vitamin B3 (Niacin)

Symptoms of Deficiency: Blurred vision, eye fatigue, and reduced blood flow to the eyes may occur.

Niacin maintains healthy blood vessels in the eyes. Meat, fish, peanuts, and mushrooms provide niacin. Low levels may cause blurred vision and eye fatigue. Niacin also helps reduce inflammation in the retina. Adequate intake supports eye circulation and retinal health. Niacin helps prevent retinal swelling caused by poor circulation.
