Melatonin may be useful in the treatment of certain eye diseases, according to a recent research review. Known to offer antioxidant benefits, melatonin may help enhance eye health by fighting off free radicals thought to contribute to eye diseases like glaucoma and uveitis (inflammation of the middle layer of the eye).
A hormone produced naturally by the body, melatonin is widely available in supplement form. Shown to help regulate sleep, melatonin supplements are often used by people struggling with jet lag or insomnia.
Past research shows that several other antioxidants may be useful in treatment or prevention of eye diseases. Vitamin C, for instance, appears to reduce eye pressure and benefit people with glaucoma. Lutein and zeaxanthin, meanwhile, may help reduce risk of cataracts (the world's leading cause of blindness). Antioxidants found in yellow or dark-green leafy vegetables, lutein and zeaxanthin have been found to shield the eyes from damage induced by ultraviolet rays.
