According to Rebuild Your Vision, vitamin A, vitamin C and vitamin E are essential for whiter, healthier eyes. Zinc, alpha-lipoic acid and selenium also help improve eye health, as does the herb ginkgo biloba.
To achieve white eyes, HealthGuidance recommends avoiding toxins such as nicotine and alcohol. Additionally, drinking a lot of water helps remove toxins from the body and encourages the production of tears, which help reduce eye redness. Using eye drops can prevent eye dryness that leads to red eyes. Getting an adequate amount of sleep is also important. A lack of sleep typically leads to tired, bloodshot eyes.
