Does drinking water help glaucoma?

Glaucoma, a complex eye condition that affects millions worldwide, has led to ongoing exploration of complementary approaches to its management. Among the many questions that arise, the potential connection between hydration and glaucoma management is one worth considering.

What is glaucoma?

Before we explore the potential impact of hydration on glaucoma, it’s vital to grasp the fundamentals of this condition. Glaucoma encompasses a group of eye diseases characterized by elevated intraocular pressure (IOP), which can ultimately result in optic nerve damage and vision loss. While the primary approach to treating glaucoma is the reduction of IOP through medications, surgical procedures, or other means, researchers are continually investigating lifestyle factors that might play a role in managing the condition.


Proper hydration is critical for overall health, and it may indirectly benefit eye health. Maintaining adequate hydration ensures blood and oxygen delivery to various tissues throughout the body, including those in the eyes. This might help support the overall health of the optic nerve and potentially reduce the risk of damage caused by elevated IOP.

Intraocular pressure

While staying well-hydrated is essential for overall health, there is limited direct evidence to suggest that drinking water can significantly lower intraocular pressure in individuals with glaucoma. The primary methods for managing IOP involve medications and treatments prescribed by ophthalmologists. However, it’s crucial to understand that proper hydration is essential to a balanced and healthy lifestyle.

Although chugging a lot of water all at once can damage not just your eyes but other body parts, so please drink in moderation. 

Holistic approach

In the management of glaucoma, a holistic approach is encouraged. Alongside prescribed medical treatments, maintaining a healthy lifestyle with a balanced diet, regular exercise, and proper hydration can contribute to overall well-being. While drinking water alone may not serve as a cure for glaucoma or a direct method for reducing IOP, it supports your body’s general health. A holistic approach can contribute to better eye health in the long term and better quality of life in general. 

To summarize, while staying well-hydrated by drinking water is a fundamental aspect of overall health, its direct impact on managing glaucoma remains inconclusive. The primary treatment for glaucoma centers on lowering intraocular pressure through prescribed medications and medical procedures, as determined by your ophthalmologist. Nevertheless, maintaining a balanced and healthy lifestyle, which includes proper hydration, is essential for your overall well-being. Remember to consult with your ophthalmologist for personalized advice on managing glaucoma and to explore all possible avenues for optimal eye health.
