The value of hydration for overall health is well-known, but its specific impact on eye health is often overlooked. The human body is composed of approximately 60% water, and maintaining proper hydration is crucial for various bodily functions, including those related to the eyes. Let’s learn more about it in this post by Northern Virginia Doctors of Optometry.
One of the most common issues associated with inadequate hydration is dry eyes. Insufficient water in the body may hinder the eyes’ ability to produce tears, which are essential for lubrication that prevents dryness and ensures clear vision. Chronic dehydration can contribute to persistent dry eye symptoms, including irritation, redness and a gritty sensation.
Hydration also influences the refractive properties of the eye. Dehydration can affect the thickness and shape of the cornea, potentially leading to temporary changes in visual acuity. Individuals may experience blurred vision or difficulty focusing when they are not adequately hydrated.
Staying hydrated is crucial for preventing eye fatigue, especially in the digital age where screen time is prevalent. Prolonged use of contact lenses and digital devices can increase tear evaporation and eye strain. Proper hydration helps maintain the tear film, reducing the risk of eye fatigue and discomfort associated with extended screen use.
The eyes are filled with a fluid called aqueous humor, which helps maintain intraocular pressure. Proper hydration is essential for regulating the balance of this fluid. In cases of dehydration, there may be an imbalance in intraocular pressure, potentially impacting the optic nerve and increasing the risk of certain eye conditions.
Eye care experts recommend the following to improve and lengthen your eyesight through ample hydration:
Don’t forget to get regular eye exams to know if your vision needs correction.
