Eat your carrots, or so we’ve been told. Is there any truth to that, though? Can eyesight be improved naturally? What is the best food for eyesight improvement? It turns out that there are certain foods good for vision. They contain key vitamins and nutrients that optimize ocular health.

Unfortunately, there is no way of reversing refractive error, such as myopia, hyperopia, astigmatism, or presbyopia. This type of visual difficulty can be treated with glasses, contact lenses, or refractive surgery.
However, there are other reasons for diminished eyesight, such as macular degeneration, that respond favorably to nutritional changes. In that sense, there are foods to improve eyesight without glasses.
What Vitamins Are Good For Eyesight?
Certain vitamin deficiencies can negatively impact how we see. Our ocular health depends on the balance of many nutrients, but some key vitamins improve eyesight.
When you think of what vitamin helps eyesight, you may instinctively think of vitamin A. It is indeed an essential nutrient for the eyes.
Vitamin A is a broad term used for a group of compounds called retinoids. Retinol is the form of vitamin A derived from animal foods. In the eye, retinol is taken up by the retinal cells to make a pigment called rhodopsin. Rhodopsin is used by rod cells in the eye to enable vision in low light. When vitamin A is deficient, problems with night vision can develop.
Xerophthalmia is the term used to describe the constellation of symptoms that arise from vitamin A deficiency, including night blindness and dry eye, among others.
Our body is constantly producing what are called free radicals. These are byproducts of our metabolic processes that take place every day of our waking life. Our body also produces antioxidants, which combat these free radicals. When there is an imbalance between free radicals and antioxidants, oxidative stress occurs. Oxidative stress is responsible for many aging processes, including cataract formation.
Vitamin C is a powerful antioxidant that we can take to fend off free radicals and possibly delay cataract formation. It has also been shown to slow the progression of macular degeneration, a potentially blinding age-related condition.
Vitamin E is another powerful antioxidant that has been shown to slow the progression of macular degeneration.
There is a myriad of B vitamins out there, and several of them have been found to be beneficial to the eyes. Folate, B6, and B12 may reduce the risk of age-related macular degeneration. Taking a B complex may also delay the onset of cataracts.
What vitamin is good for eyesight? Although there isn’t just one, lutein is pretty high up on the list. It is one of the best vitamins to help eyesight.
Lutein is a carotenoid related to vitamin A and beta-carotene. It is beneficial for the macula, slowing the progression of macular degeneration. It has the ability to filter out blue light emitted by digital devices. It may also delay cataract progression.
