The eye is a complex organ and the foremost body part of a human being. For the functioning of the eyes, different vitamins and nutrients are needed. There are many vitamins for eyes that are important for proper vision. Some of the top vitamins for the eyes are Vitamin A which helps with clear vision by maintaining a clear cornea, which is the outside layer of the eye. Some sources of Vitamin A are sweet potatoes, green vegetables, pumpkin etc. 

Another good vitamin for the eyes is Vitamin C which acts as an antioxidant and protects the eyes against the damage of free radicals. Some sources of Vitamin C, such as citrus-type fruits, bell peppers etc., can be consumed in this regard. For the protection of cells of the eyes, Vitamin E works as an antioxidant that protects the eyes from unstable molecules, free radicals etc. Some sources of Vitamin E are avocado, salmon, leafy vegetables etc. There are several B vitamins that also help the eyes to work properly, such as Vitamin B12, B6, B9, and others. 

What Else Should You Know

This mixture of vitamins helps to lower the level of homocysteine, which is a protein in the body that increases the risk of developing AMD. Vitamin B contains rich foods and is the source of these helpful ingredients. There is a plant chemical called Lutein which is a part of carotenoid, that is the family of antioxidants which is found in the cells of plants and the vibrant colours that are seen in many vegetables and fruits, such as orange, deep red and yellow. The Lutein in the body of a human being protects the eyes as it plays a role in suppressing the inflammation of the eyes and defending against oxidative stress and free radicals. The Lutein chemical helps to clear the vision and improves visual contrast sensitivity. It also protects the tissues of the eyes from sun rays and protects from their death and cell loss; they also protect the eyes from harmful blue lights. In the retina, it helps to convert the light signals to electrical signals and protects the transaction of those signals into the brain. It also protects from myopia which is nearsightedness, and from ROP (Retinopathy of Prematurity). 

It also safeguards the eyes from age-related macular degeneration (AMD), which causes blindness and visual impairment permanently, and is mostly seen in developing countries. It helps to stop the progression of AMD to blindness also in the last stage. Bilberry, also called Vaccinium myrtillus, is a small fruit native to Northern Europe, also known as European Blueberries. It contains a chemical called anthocyanosides which is rich with antioxidant properties that protect the eyes from damage to the cells, macular degeneration, cataracts, glaucoma etc. It is a source of antioxidants that reduce inflammation and protect against oxidative stress related to the eyes. The Bilberry helps to strengthen the blood vessel walls. There is some proof that shows how the bilberry works in the case of eye treatments. In the case of eye fatigue, it acts as a promising treatment option. Some years back, there was an experiment created with 281 people who used the video display terminal, and researchers proved that the blueberry extract helps to improve the subjective and objective measures of eye fatigue. In the preliminary studies, the bilberry extract plays a crucial role in the treatment of retinal disorders as well as other eyesight-related issues. 

There are many experiments done which indicate that bilberry protects the retinal cell against degeneration in the case of animals. Bilberry is one of the best antioxidants with rich dietary sources and is very useful in case of the eyes as well as overall health improvements. Zeaxanthin, which is a carotenoid (a type of organic pigment that is rich in Vitamin A), can be found in the human eye, and it works as a light filter that protects the eyes from damage due to the sun’s ultraviolet rays. There are some foods rich in Zeaxanthin, such as oranges, eggs, grapes, mango, leafy vegetables etc. It can be very useful in case of age-related vision loss, cataracts and other conditions related to damage of the eyes. Zeaxanthin is made up of two carotenoids in the eyes that contain Lutein and meso-Zeaxanthin. The Lutein and Zeaxanthin work together within the eye exactly in the centre and within the peripheral regions of the retina, which forms the macular pigment in the eye. They both work to reduce the risk of eye diseases. The cause of glaucoma and diabetic retinopathy is due to the high blood sugar levels causing damage to vision. For this purpose, Zeaxanthin plays a vital role in protecting our eyes.
