The research found that the average office worker spends 1,700 hours per year in front of a computer screen. And that doesn’t include our addiction to phones and other digital devices. All this screen time has led to an increase in complaints of eye strain, dry eye, headaches, and insomnia. Eyepic Eye Care and the American Academy of Ophthalmology are offering tips to desk workers everywhere whose eyes may need relief from too much screen time and to protect their eyes from digital eye strain.
What is digital eye strain?
Eye strain can mean different things to different people. “Eye strain is more of a symptom than an actual condition,” explains Laurie Barber, MD, a comprehensive ophthalmologist in Little Rock, Ark. “People use the term differently. One person may mean their eyes are tired or watery, while another may have blurred vision. Some people may have headaches they attribute to eye strain, and others may have facial muscle fatigue from squinting for long periods because they are not wearing the correct glasses.”
Digital eye strain includes a collection of eye problems that can happen after staring at a screen for too long. Symptoms can include blurry vision, headaches, and tired, dry eyes.
Why does computer use strain the eyes more than reading print material?
Mainly because people tend to blink less while using computers. Focusing the eyes on computer screens or other digital displays has been shown to reduce a person’s blink rate by a third to a half, which tends to dry out the eyes. We also tend to view digital devices at less than ideal distances or angles. As children are spending more time in front of devices, it is important to know if you are protecting your children’s eyes from digital eye strain as well.

What can I do to get relief from digital eye strain?
You don’t need to buy expensive computer glasses to get relief. In fact, a recent study concluded that blue light filters are no more effective at reducing the symptoms of digital eye strain than a neutral filter. Instead, try altering your environment with these simple tips:
- Keep your distance: The eyes actually have to work harder to see close up than far away. Try keeping the monitor or screen at arm’s length, about 25 inches away. Position the screen so your eye gaze is slightly downward.
- Reduce glare: Glass screens can produce glare that can aggravate the eye. Try using a matte screen filter.
Adjust lighting: If a screen is much brighter than the surrounding light, your eyes have to work harder to see. Adjust your room lighting and try increasing the contrast on your screen to reduce eye strain.
- Give your eyes a break: Remember to blink and follow the 20-20-20 rule. Take a break every 20 minutes by looking at an object 20 feet away for 20 seconds. Looking into the distance allows your eyes to relax.
- Keep eyes moist: Keep artificial tears at hand to help lubricate your eyes when they feel dry. Consider using a desktop humidifier. Office buildings have humidity-controlled environments that suck moisture out of the air. In winter, heaters on high can further dry your eyes.
- Stop using devices before bed: There is evidence that blue light may affect the body’s circadian rhythm, our natural wake and sleep cycle. During the day, blue light wakes us up and stimulates us. So, too much blue light exposure late at night from your phone or other devices may make it harder to get to sleep. Limit screen time one to two hours before bedtime. Use nighttime settings on devices and computers that minimize blue light exposure.
Is digital eye strain from computer usage serious?
“Eyestrain can be frustrating. But it usually isn’t serious and goes away once you rest your eyes or take other steps to reduce your eye discomfort,” said Dianna L. Seldomridge, M.D. “If these tips don’t work for you, you may have an underlying eye problem, such as eye muscle imbalance or uncorrected vision, which can cause or worsen computer eyestrain.”
Those experiencing consistently dry red eyes or eye pain should visit an ophthalmologist, a physician specializing in medical and surgical eye care. Schedule an appointment today.
