Hydrate Your Way to Brighter Eyes: The Surprising Benefits of Drinking Water for Dry Eyes

Dry eyes can be an uncomfortable and irritating condition that affects many people, especially as they age. It occurs when the eyes do not produce enough tears or when the tears evaporate too quickly. The result is a dry, irritated, and inflamed feeling in the eyes. So, do you reach for the eye drops or is there a more natural solution? In this article, we will explore the question of whether drinking water can help with dry eyes.

Why Do We Need Tears?

You may be wondering why tears are so essential to our eyes. For one, they help keep our eyes moist and lubricated. They also help to protect the eyes from infections, wash out irritants, and provide vital nutrients to keep the eye healthy. Tears are made up of three layers: an outer fatty layer, a middle watery layer, and an inner mucous layer. Each layer plays a crucial role in keeping our eyes healthy and functioning correctly.

How Does Dehydration Affect Dry Eyes?

Dehydration is a significant cause of dry eyes. When the body does not have enough water, it will not produce enough tears to keep the eyes moist. The fatty outer layer of tears is also reduced, causing the tears to evaporate quickly. This leads to dry, irritated, and uncomfortable eyes. If you are consistently dehydrated, it can also cause chronic dry eyes, leading to other eye problems such as corneal damage and vision impairment. Therefore, it is essential to stay hydrated to keep your eyes moist and healthy.

How Much Water Should You Drink for Dry Eyes?

The recommended daily water intake varies depending on several factors, such as age, weight, and activity level. However, the general rule of thumb is to drink at least eight 8-ounce glasses of water per day. Besides drinking water, you can also increase your fluid intake by eating foods with high water content, such as fruits and vegetables. Always keep a water bottle handy, so you can stay hydrated throughout the day.

Other Ways to Relieve Dry Eyes

Along with staying hydrated, there are other ways to relieve dry eyes. Blinking frequently while using digital devices can help prevent eyes from drying out. Also, try to take regular breaks from staring at screens to give your eyes a rest. Using a humidifier in your home or office can also help add moisture to the air and prevent dry eyes. If your dry eyes are persistent, consult an eye doctor for proper diagnosis and treatment. They may prescribe eye drops or suggest other methods to relieve your symptoms.


In conclusion, drinking enough water is essential for maintaining good eye health and preventing dry eyes. While it may not be the only solution, it is a simple and natural way to help keep your eyes moist and comfortable. Other methods, such as using eye drops and implementing frequent screen breaks, can further aid in relieving dry eyes. Remember to always stay hydrated and listen to your body’s signals of when it needs more water. Your eyes will thank you!
