There’s no escaping screen time. From conferencing with our colleagues to connecting with our loved ones, laptops and smartphones function to make our social worlds possible. Unfortunately, spending too much time on them can also lead to dry eyes.
How Screen Time Hurts Our Eyes
Have you ever stood up after a long day of emails and online meetings, only to find that your eyes were on fire? Normally, we generate tears every time we blink, a nourishing mixture of water, oils, and proteins that protects our eyes. These “basal tears” help wash out debris and keep our eyes well-lubricated.
Unfortunately, staring at a computer or smartphone lowers our blink rate by 66% — enough to impede the production of those all-important basal tears. That’s why our eyes tend to itch and burn at the end of a long workday.
Computer Eye Strain Symptoms
Staring at a computer for hours at a time can do more than dry out our eyes. Pay close attention to your body after a long stretch of screen time, and you might notice other signs of discomfort too.
The American Optometric Association has identified a cluster of problems associated with digital eye strain. Taken together, they form a condition called Computer Vision Syndrome. Despite its name, however, CVS has implications beyond vision alone. Common symptoms include:
- Light sensitivity
- Neck, shoulder, and back pain
Long-Term Effects of Computer Vision Syndrome
In recent years, the incidence of Computer Vision Syndrome has skyrocketed. It now affects 75% of frequent computer-users, especially those 40 and older.
Given how prevalent CVS has become, it’s no surprise that researchers are working hard to tease out its long-term impact on the body. It’s still too early to map out how computer eye strain will affect our quality of life years down the road. But while we wait for the scientific consensus to come in, it’s important to protect our eyes now.
How to Protect Your Eyes from Computer Eye Strain
We all want to look out for our ocular health, but ditching our laptops and smartphones might not be an option. Luckily, there are strategies for protecting our eyes without sacrificing screen time entirely.
Here are some ways to use digital devices responsibly — and keep computer eye strain symptoms at bay.
Take breaks to rest your eyes
To make sure our blink rate doesn’t dip too low, it’s important to avoid hours-long stretches of uninterrupted screen time. For an easy-to-remember strategy to give your eyes the rest they need, follow the 20-20-20-rule. After every 20 minutes of screen time, take 20 seconds to look at something 20 feet away.
Optimize your workspace
Our workstations aren’t always set up with our eyes in mind. To ensure your office setup isn’t making your eye strain worse, invest in an anti-glare monitor. Don’t forget to set your screen at a comfortable distance — about an arm’s length away, and level with your gaze.
Look into dry eye treatment
If you’re already suffering from Computer Vision Syndrome, don’t panic. There are ways to restore your eye health and have you seeing comfortably again.
For mild cases of dry eye, an over-the-counter eye lubricant might relieve your symptoms. But if the gritty, fiery sensations don’t respond to non-prescription drops, you still have options for dry eye treatment.
