Does Drinking Water Improve Dry Eyes? Here’s What Really Happens
The Link Between Hydration and Eye Health
Dry eyes can be surprisingly annoying. That gritty feeling? Ugh. And while most people reach for eye drops (understandably), some health experts suggest the real solution might be… water. But does drinking water actually help with dry eyes?
Well—yes and no. It's a bit more nuanced than just "drink 8 glasses and boom, problem solved." So let’s break it down.
What Causes Dry Eyes in the First Place?
Tear Production Gone Wrong
Our eyes produce three layers of tears: oily, watery, and mucous. Each layer has its job, and if one of them slacks off, hello discomfort. Common causes of dry eyes include:
Staring at screens too long (yep, guilty)
Aging (yep, again)
Certain medications (antihistamines, antidepressants)
Air conditioning or dry environments
Autoimmune conditions like Sjögren’s syndrome
So, if your body isn’t making enough tears—or the right kind of tears—your eyes can get dry and irritated.
Dehydration and Eye Moisture
Now here’s where water enters the chat.
When you're dehydrated, your body starts rationing water. Vital organs first. Skin, lips, eyes… last in line. Which means? You might not produce enough aqueous (watery) layer in your tears. And boom—dry eyes.
Can Drinking More Water Help?
Yes, But Not Instantly
Let’s be real. Chugging a glass of water won't magically moisten your eyeballs in 10 minutes. It’s more of a long game.
Over time, proper hydration can:
Support tear production
Improve tear quality
Reduce inflammation linked to dry eyes
Some small studies (nothing massive or groundbreaking yet) suggest that people who increase water intake see slight improvements in symptoms. But it's not a miracle cure.
Personal Note – It Did Help Me (Kind Of)
Okay, real talk. I used to work 10+ hours a day staring at my laptop, and my eyes would get so dry by 3 PM. I tried drops, eye masks, humidifiers—you name it.
Then I started drinking 2 liters of water per day. Not just sipping randomly, but like, consistently. It didn’t solve everything, but after two weeks? I genuinely felt less “blinky.” Less irritated. Maybe it was placebo, maybe not—but it felt better.
Other Ways to Help Dry Eyes (Besides Guzzling Water)
Adjust Your Environment
Use a humidifier, especially in winter
Avoid direct AC/fan air on your face
Take screen breaks (20-20-20 rule is gold: every 20 mins, look at something 20 feet away for 20 seconds)
Eat More Omega-3s
Yep—what you eat can matter too. Omega-3 fatty acids (like in salmon, flaxseeds, walnuts) help support the oily layer of your tears. Less evaporation = happier eyes.
Use Preservative-Free Eye Drops
Not all drops are equal. Some have preservatives that can make things worse if you overuse them. Try preservative-free formulas if you're going the artificial tears route.
So, Should You Start Drinking More Water?
Absolutely. Even if it doesn’t completely fix your dry eyes, staying hydrated helps your whole body run better—including your tear glands.
Just don’t expect miracles overnight. Think of it like skincare: consistent hydration over time = better baseline health.
Bottom line? Water won’t hurt. And paired with other smart habits, it just might be the extra drop (pun intended) you need.
