Hydration for Healthy Eyes: The Truth About Drinking Water and Dry Eyes


Does Drinking Water Help Dry Eyes?

Dry eyes can be a common and uncomfortable problem for many people, affecting up to 50% of adults over the age of 50. It is even more prevalent in today’s society where we spend countless hours staring at screens, whether it’s working on the computer, watching TV, or scrolling through our phones. One of the most popular remedies for dry eyes is to drink more water, but is this really effective? In this article, we will explore the role of water in dry eyes and whether drinking more of it can truly help alleviate this condition.

What Causes Dry Eyes?

Before we dive into the benefits of drinking water for dry eyes, it’s important to understand what causes this condition in the first place. Dry eyes occur when the eyes do not produce enough tears or when the tears evaporate too quickly. This can lead to symptoms such as burning, itching, redness, sensitivity to light, and even blurred vision. Some common causes of dry eyes include:

  • Age – As we get older, our tear production decreases, making us more prone to dry eyes.
  • Environmental factors – Exposure to dry, windy, or smoky environments can cause tears to evaporate more quickly.
  • Medical conditions – Certain medical conditions such as diabetes, thyroid disorders, and autoimmune diseases can contribute to dry eyes.
  • Medications – Some medications can reduce tear production or cause dry eyes as a side effect.
  • Hormonal changes – Women may experience dry eyes during pregnancy, menopause, or while taking birth control pills.
  • Long-term screen use – Staring at screens for prolonged periods can cause us to blink less, leading to dry eyes.

The Role of Water in our Body

Water is essential for our overall health and plays a crucial role in maintaining proper bodily functions. It makes up about 60% of our body weight and is involved in almost every bodily process, including digestion, circulation, and maintenance of body temperature. It also helps flush out toxins and waste products, keeping our bodies functioning optimally.

Benefits of Drinking Water for Dry Eyes

Since our eyes also contain a significant amount of water, it makes sense that staying hydrated can have a positive impact on dry eyes. Here are some ways that drinking water can benefit those suffering from dry eyes:

Increases Tear Production

One of the main ways water helps with dry eyes is by increasing the production of tears. Drinking water helps to replenish the water content in our bodies, including our eyes. This, in turn, stimulates tear production, providing much-needed moisture to the eyes. Additionally, drinking water can help thin out the oil in our tears, making them spread more evenly over the surface of the eyes.

Reduces Eye Strain

As mentioned earlier, prolonged screen use can cause dry eyes. Drinking water helps keep our bodies hydrated, preventing dehydration that can lead to eye strain. When our bodies are dehydrated, it can cause us to blink less, leading to dry and tired eyes. Staying hydrated can help prevent this from happening and reduce eye strain.

Improves Overall Eye Health

By staying hydrated, we are also helping to maintain overall eye health. Water is essential for delivering nutrients and oxygen to the eyes, keeping them nourished and healthy. Drinking enough water also helps to flush out toxins and prevent eye infections, which can contribute to dry eyes.

How Much Water Should You Drink?

The amount of water a person needs to drink can vary from person to person and is dependent on various factors such as age, weight, and activity level. The National Academies of Sciences, Engineering, and Medicine recommends that men should drink about 15.5 cups (3.7 liters) of total beverages and women should drink about 11.5 cups (2.7 liters) of total beverages per day. Keep in mind that this includes water from food sources, such as fruits and vegetables.

Other Tips for Relieving Dry Eyes

While drinking water can certainly help with dry eyes, there are other steps you can take to alleviate this condition:

  • Use artificial tears – Over-the-counter eye drops or artificial tears can provide temporary relief for dry eyes.
  • Take breaks from screen time – Make sure to take regular breaks from staring at screens to give your eyes a rest.
  • Wear sunglasses – When outdoors, wear sunglasses to protect your eyes from harsh winds and sunlight.
  • Use a humidifier – Using a humidifier in your home can help add moisture to the air, preventing your eyes from drying out.
  • Consult with your doctor – If your dry eyes persist or become severe, it’s important to consult with your doctor. They can help determine the root cause of your dry eyes and provide a treatment plan.

Remember, drinking water is just one piece of the puzzle when it comes to managing dry eyes. It’s essential to take care of your overall health and incorporate other practices to prevent and alleviate dry eyes.


In conclusion, drinking water can certainly help with dry eyes, but it is not a cure-all solution. It’s essential to stay hydrated to maintain overall eye health, but dry eyes can also be caused by various factors that may require additional
