Digital eye strain refers to the discomfort, including burning, blurring, and aching, experienced after prolonged use of laptops or phones. Approximately 60 million people globally face this issue. Let’s explore its causes, symptoms, and recommended treatments.
What Are the Symptoms of Digital Eye Strain?
According to Cleveland Clinic, the prevalent symptoms of digital eye strain include blurry vision, watery eyes, dry eyes, and fatigue in the eyes.
Individuals with computer vision syndrome often report additional issues such as red eyes, a feeling of a foreign body in the eye, light sensitivity, and double vision. It is estimated that 60 million people worldwide suffer from CVS, with one million new cases appearing each year, as noted in a BMC Public Health study. Symptoms can extend beyond the eyes. A 2022 review in the European Journal of Ophthalmology highlights that extraocular symptoms may include musculoskeletal issues, causing inconvenience in daily activities, such as headaches, neck or shoulder pain, and back pain.
Maybe the cost of Ozempic finally got to you. Maybe the nausea never really went away, or you hit your goal weight and figured it was time to discontinue use. Whatever pushed you toward your last dose, one question tends to follow close behind: what happens now? Going off Ozempic isn’t as simple as just […]
What Causes Computer Vision Syndrome From Screen Use?
According to Cleveland Clinic, computer vision syndrome arises from prolonged use of digital devices without sufficient breaks. Devices like computers, tablets, e-readers, and smartphones can all contribute to this condition.
Warby Parker identifies three main factors. Users tend to blink less while looking at digital screens, view screens with glare or poor lighting, and hold devices too close to their faces. These habits force the eyes to exert more effort than usual, often resulting in headaches, blurry vision, and a gritty sensation after extended periods in front of a monitor.
How Can You Prevent Digital Eye Strain at Your Desk?
The most effective solution is to adjust your workspace, with the American Optometric Association emphasizing the importance of screen positioning.
“Most people find it more comfortable to view a computer when the eyes are looking downward. Optimally, the computer screen should be 15 to 20 degrees below eye level (about 4 or 5 inches) as measured from the center of the screen and 20 to 28 inches from the eyes,” the association notes.
The association also suggests arranging the screen to minimize glare from overhead lights or windows, using blinds or drapes, and opting for lower-wattage bulbs in desk lamps. Maintaining a monitor at arm’s length and a neutral angle can also alleviate neck and back strain. Cedars-Sinai recommends seeing an eye care provider annually if you use corrective lenses.
How Is Digital Eye Strain Treated by Doctors?
As noted by the American Diabetes Association, most symptoms are temporary and fade after stopping computer work. However, if discomfort persists, a comprehensive eye exam is advised.
Cleveland Clinic advises consciously blinking more often to promote tear production and eye moisture. Healthcare providers might also recommend over-the-counter or prescription eye drops. The American Diabetes Association points out that “90 percent of patients do not talk with their eye care provider about computer vision syndrome symptoms,” highlighting the importance of discussing this at your next appointment. If redness, blurriness, or pain persists for several days, consulting a professional is preferable to waiting.
Contact lens users frequently experience dry eyes when using digital devices for extended periods, according to the American Academy of Ophthalmology.
The academy recommends taking breaks by wearing glasses instead of contacts on intensive computer days, avoiding sleeping in contacts even if they are labeled “extended wear,” and adhering to good cleaning practices to prevent irritation. Some symptoms may require professional attention rather than relying on eye drops. If your eyes remain red, blurry, or watery, or if they become sensitive to light or painful, consult your ophthalmologist. Combining these practices with workspace adjustments suggested by the American Optometric Association can help prevent digital eye strain from becoming a persistent issue.
