Hydration is key to visual health
11 January 2024
Eye health is a critical component of our overall well-being, and many factors can influence it, including proper hydration. Often underestimated, the relationship between the amount of water we consume and the health of our eyes is a crucial aspect that deserves attention.
The human eye and its dependence on water:
The human eye is a complex and delicate structure that requires precise balance to function properly. 80% of the eyeball is made up of water, which highlights the importance of maintaining adequate hydration for proper functioning. Water is essential for maintaining moisture in the cornea, the transparent tissue at the front of the eye. In addition, it contributes to the constant lubrication of the eyes, facilitating blinking and protecting against irritation.
Dry eyes and dehydration:
Dry eyes are one of the most common problems related to lack of hydration. When the body is dehydrated, it has difficulty producing enough tears, which can lead to irritation, burning sensations, and, in more severe cases, damage to the ocular surface. Symptoms of dry eyes include blurred vision, itching, and eyestrain, which can negatively impact quality of life.
The connection between overall hydration and eye health:
Hydration not only directly benefits the eyes, but also contributes to the overall health of the body, which in turn positively impacts vision. Good hydration helps maintain proper blood circulation, ensuring that the eyes receive the nutrients necessary to function properly.
Tips to maintain good eye hydration:
Drink enough water: The general recommendation is to consume at least eight glasses of water a day. This can vary depending on factors such as physical activity, weather, and individual health.
Include water-rich foods in your diet: Fruits and vegetables with high water content, such as cucumbers, watermelons, and strawberries, can contribute significantly to hydration.
Avoid excess caffeine and alcohol: these substances can have dehydrating effects, so it is important to moderate their consumption and balance them with an adequate intake of water.
Use artificial tears when necessary: In situations where the eyes may be exposed to dry conditions, such as heated or air-conditioned environments, the use of artificial tears may provide relief.
