Screen Time and Dry Eye: How Digital Devices Drive Dry Eye
Quick answer: Screen time and dry eye are linked because people blink about two-thirds less while looking at screens. Fewer blinks mean poorer tears and, over time, clogged oil glands. Follow the 20-20-20 rule, blink fully, and clean your eyelids every day.
We all know the feeling: tired, burning eyes after a long day on our phones and computers. The connection between screen time and dry eye is more than a temporary annoyance. Hours of focusing on digital devices can lead to dry eye, a condition that makes your eyes feel scratchy, uncomfortable, and even blurry. The good news is that a few simple changes can keep your eyes comfortable, even if your job or your free time keeps you on screens.
Dry Eye Is on the Rise
Ocular surface diseases such as meibomian gland dysfunction (MGD) and dry eye disease are becoming more common in the United States. A recent study estimated that 6.8% of U.S. adults have been diagnosed with dry eye, and MGD is involved in the majority of dry eye cases. For many people, dry eye is disruptive, making it uncomfortable to be outdoors, watch TV, or simply keep their eyes open.
One everyday behavior is helping to drive this trend: looking at screens.
Americans continue to increase their screen time. From 2013 to 2022, daily screen time in the United States grew by about 50 minutes, to just over 7 hours per day, split between streaming TV and video games (about 3 hours) and mobile phones (about 4 hours). This is not just an American trend; screen time is growing around the world.
Why Screen Time Causes Dry Eye
1. You Blink Less on Screens
When you focus on a screen, you blink much less often. According to research published in Computers in Human Behavior, the average resting blink rate is about 22 blinks per minute, but it drops to about 7 blinks per minute while looking at a screen, roughly one-third as often. Fewer blinks let your tears evaporate and become more concentrated (higher osmolarity), so they coat the eye poorly and dry off too quickly. Either way, the result is discomfort. It can also make your vision blur on and off, which our guide to dry eye and blurry vision explains.
A study published by the NIH measured tear quality in the morning and again after extended computer use and found a clear decline after screen time, likely because of the lower blink rate.
2. Your Oil Glands Work Less
Blinking is what squeezes oil out of the meibomian glands along your lash line. When you blink less, those glands secrete less. According to Review of Ophthalmology, a low blink rate can reduce gland secretion, and over time it is associated with gland degradation. The glands can become clogged or even shrink (atrophy). Together, these problems are called meibomian gland dysfunction (MGD).
What makes MGD tricky is that many people feel nothing at first. Your glands can lose function before symptoms appear, and by the time you notice discomfort, some of that loss may not be reversible. That is why prevention matters.
How to Relieve Dry Eye From Screen Time
1. Follow the 20-20-20 Rule
Every 20 minutes, look at something about 20 feet away for 20 seconds. Some eye doctors also recommend blinking fully several times during that break. Make sure your desk or TV setup lets you sit comfortably, too; some headaches and neck pain blamed on eye strain actually come from poor posture. For more ideas, see our screen time prevention plan.
2. Clean Your Eyelids Every Day
Research on MGD and dry eye points to the same habit: washing your eyelids daily. Studies most often support tea tree oil cleansers containing terpinen-4-ol, and other options such as hypochlorous acid can also help relieve symptoms. A gentle eyelid cleanser used once a day removes the oil, debris, and bacteria that clog your glands. Here is how to properly wash your eyelids, and how to make it a daily habit that sticks.
3. Talk to Your Eye Doctor About Omega-3s
Some people find omega-3 supplements helpful for tear quality, though research results are mixed; our article on what the DREAM study found about omega-3 for dry eye breaks down the evidence. If you want to try one, these optometrist-recommended ProOmega options are a good place to start.
4. Use Short-Term Relief When You Need It
If your eyes hurt right now, two tools are consistently recommended. First, a warm compress heated in the microwave provides quick relief and, with regular use, can help improve oil gland flow. Second, lubricating eye drops made for dry eye. Popular options at Peeq Pro include Systane Complete PF, Refresh Optive Advanced, Optase Dry Eye Intense, and Optase MGD Advanced. Wondering how often is too often? See whether it is bad to use eye drops every day.
Other Things That Can Make Screen-Related Dry Eye Worse
Screen time often stacks with other dry eye triggers. Common medications can reduce tear production, including allergy pills (see antihistamines and dry eyes) and some antidepressants (see Lexapro and dry eyes). If your eyes are worst first thing in the morning, read why your eyes are dry when you wake up.
The Bottom Line
Screen time is not going away, but dry eye does not have to come with it. Take regular 20-20-20 breaks, blink fully, clean your eyelids every day, and use drops or a warm compress when you need extra relief. If symptoms continue, see your eye doctor.
Don't let dry eyes slow you down. Start these habits today and keep your eyes comfortable in the digital age.
