Dry eye syndrome or Dry Eye Disease (DED) is a chronic condition of insufficient lubrication and moisture on the surface of the eye. A person suffering from this condition can experience subtle but constant eye irritation to significant inflammation of the eye. Severe cases can lead to the scarring of the front surface of the eye. Alternative medical terms of dry eyes include:
This is generally the dryness and inflammation of the cornea.
This condition emphasizes the inadequateness of tears that helps in keeping the eyes hydrated.
This is the condition in which the dryness affects both the cornea and the conjunctiva.
A recent research showed the prevalence of dry eyes ranging from 5 percent to as high as around 50 percent in different populations across the world.
Underlying health conditions such as retinopathy, diabetic, age-related macular degeneration, cataracts, glaucoma, and can also cause dryness in eyes. So, apart from treating the condition using medicines, proper supplementation of nutrients is also imperative. Vitamins play a key role in providing proper nutrition to improve eye health. Here is a list of vitamins that help maintain eye health.
This vitamin plays a crucial role in vision by maintaining a clear cornea- the covering outside the eye. Vitamin A has also replenished rhodopsin, a protein in the eyes allowing you to see in low light conditions. Deficiency in vitamin A can cause Xerophthalmia, which is a progressive eye disease resulting in night blindness. The same deficiency can cause dry eyes. Vitamin-A-rich foods include sweet potatoes, leafy green vegetables, pumpkins, and bell peppers.
Also known as vitamin B, it is associated with eye health. Vitamin B contains an antioxidant, riboflavin that can reduce oxidative stress in the body, including eyes, as it helps in hydrating the eyes. Foods rich in riboflavin include fortified cereals, milk, oats, yogurt, and beef.
Vitamin B1 or Thiamine helps in maintaining proper cell function by converting food into energy. It also helps in reducing the risk of cataracts. Moreover, vitamin B1 has been proposed as a potential treatment for various conditions that cause dry eyes. Some food sources that are rich in thiamine include whole grains, meat, breakfast cereals, fish, bread, and pasta.
The key function of antioxidant-rich vitamin B3 or niacin helps in converting food into energy. Recent studies have also shown that vitamin B3 may help in preventing glaucoma, a condition in which the optic nerve of the eye is damaged. Some food sources rich in niacin are poultry, mushrooms, beef, fish, peanuts, and legumes.
Dry eyes are usually associated with oxidative stress, which is an imbalance between free radicals and antioxidants in the body. Vitamin E is an antioxidant-rich that helps to protect eye cells from damage by free radicals. Foods rich in vitamin E include seeds, nuts, and cooking oils, avocado, Salmon, and leafy green vegetables are also good sources.
Apart from including these vitamins in the daily diet, it is also important to steer clear from some foods that aggravate the condition of dry eyes. Here are some foods that should be avoided if a person is suffering from dry eyes:

Possibly, the best way to stay hydrated is to drink a glass of water before every drink of alcohol.
