Appropriate foods and supplements
Carotenoids are red, yellow and orange foods that act as antioxidants in the body, such as the beta-carotene found in carrots, sweet potatoes and pumpkin. Carotenoids are converted to vitamin A, which is known to help maintain good vision.
Lutein and zeaxanthin
Lutein and zeaxanthin are two common carotenoids related to eye health. Studies have shown that they help prevent macular degeneration. Kale contains many of these two substances, but if adequate amounts are difficult to obtain, supplements are equally beneficial.
Zinc is a mineral present in the cornea and plays an important antioxidant role in corneal function. Compared to other organs, the concentration of zinc in the eyes is high. According to one study, zinc, combined with vitamins C and E and beta-carotene, may have delayed the development of the disease in patients with macular degeneration. Zinc deficiency is also linked to night blindness.
Vitamin C is also found in the retina and low levels of vitamin C in the blood have been shown to increase the risk of macular degeneration and cataracts.
Blueberries contain flavonoids that promote good vision. They are also found in other foods such as green tea, chocolate, wine and citrus fruits.
Ginkgo biloba contains flavonoids and studies have shown that ginko biloba increases circulation to the optic nerve and helps reduce oxidative stress, while preventing the condition from worsening in glaucoma patients.
Omega-3s have been shown to combat dry eyes thanks to their anti-inflammatory properties. Foods rich in Omega-3 are fatty fish, chia seeds or supplements based on algae or fish.
Pine bark extract
Pine bark extract was originally used as a perfume by indigenous peoples in North America and Asia and has been shown to neutralize starches.
Spirulina is a blue-green algae that is easy to digest and absorb. In particular, it contains vitamin B6, which can help relieve dry eyes in people suffering from vitamin deficiency.
Antioxidants play an important role in the fight against eye diseases. Oxidative stress is a major factor contributing to aging in general and eye disease in particular. Antioxidants help to protect and minimize eye disease due to oxidative stress.
