Clearing the Facts: The Impact of Hydration on Your Eye Health

When it comes to maintaining good health, drinking enough water is often emphasized. But what about the health of our eyes? Can drinking water really have an impact on our vision and eye health? In this article, we’ll explore the relationship between drinking water and our eyes, and whether it truly can help improve our eye health.

The Importance of Water for Our Bodies

First, let’s delve into why drinking water is important for overall health. Our bodies are made up of about 60% water, and it plays a crucial role in maintaining bodily functions. Water helps regulate body temperature, aids in digestion, removes waste and toxins from our bodies, and helps transport nutrients to our cells. It also ensures that our joints stay lubricated and our tissues and organs are well-nourished.

So, it’s safe to say that without sufficient water intake, our bodies wouldn’t be able to function properly. Dehydration can cause a range of health issues, from digestive problems to headaches and fatigue. And since our eyes are a part of our body, they too are affected by our hydration levels.

The Connection Between Water and Eye Health

Our eyes need water to function properly, just like the rest of our body. Tears, which help keep our eyes clean and lubricated, are primarily made up of water. When we don’t drink enough water, our tear production can decrease, leading to dry eyes and irritation. This can make it difficult to see clearly and comfortably.

In addition, water can help flush out toxins and impurities from our bodies, including those that may affect the delicate tissues in our eyes. Some research suggests that drinking water can help reduce the risk of developing cataracts, one of the leading causes of vision loss in older adults.

Another way water may impact our eye health is by improving circulation. Proper circulation is essential for delivering oxygen and nutrients to our eyes, and water can help keep our blood thin and flowing smoothly, reducing the risk of eye damage caused by high blood pressure or blood clots.

The Connection Between Dehydration and Eye Strain

One of the most common symptoms of dehydration is eye strain. When we are dehydrated, our eyes can become dry, red, and irritated, making it difficult to focus and causing our vision to become blurry. This is especially true for those who work on computers or spend a lot of time looking at screens. The more we blink, the more our eyes are lubricated with tears, and when we’re dehydrated, we tend to blink less, leading to eye strain.

How Much Water Should I Be Drinking?

While there is no magic number for how much water each person should drink, the general rule is to drink at least eight glasses of water per day. But this recommendation can vary based on various factors, such as age, activity level, and overall health. It’s essential to listen to our bodies and drink water when we feel thirsty.

In addition, we can also get water from other sources, such as fruits and vegetables, broth-based soups, and herbal teas. However, caffeinated drinks like coffee and soda can have a diuretic effect and should not be counted towards our daily water intake.

Other Ways to Keep Our Eyes Healthy

While drinking enough water is beneficial for our overall eye health, there are other things we can do to protect our vision:

  • Eat a balanced diet rich in fruits and vegetables, especially those high in antioxidants like carrots and dark leafy greens.
  • Give our eyes regular breaks from screen time, especially when working on a computer or phone. The 20-20-20 rule suggests taking a 20-second break to look at something 20 feet away every 20 minutes.
  • Wear sunglasses to protect our eyes from harmful UV rays.
  • Practice good hygiene, such as washing our hands before touching our eyes, and properly cleaning and storing our contact lenses.


In summary, drinking enough water is crucial for maintaining good overall health, including the health of our eyes. Not only does it help keep our eyes lubricated and flush out toxins, but it can also reduce the risk of certain eye conditions and relieve eye strain caused by dehydration. So, remember to stay hydrated and make drinking water a part of your daily routine, and your eyes will thank you for it!
