Tablets, computers, and cell phones are digital tools that are an inescapable part of the modern world. While these devices make daily life easier, allowing you to do everything from ordering food to sending emails, they also increase the risk of eye injuries. Digital eye strain refers to the discomfort that comes with staring at a screen all day. Find out how to address it below.

Why Digital Eye Strain Occurs

Screens aren’t static. The words and image they present are created by combining thousands of tiny points of light. Called pixels, these are brighter in the center and dimmer toward the edges, making it difficult for your eyes to focus. Instead, they involuntarily try to revert to a reduced focus level, known as the resting point of accommodation (RPA). As the eyes fluctuate between an attempt to attain clarity and the RPA state, the muscles need to work harder than usual, creating fatigue.

Symptoms of this condition include dry, tired, and twitching eyes, as well as headaches, blurry sight, and neck and shoulder pain. The more screen time you put in, the worse these signs — and the potential for further eye injuries — are likely to get.

How to Avoid Screen-Related Eye Injuries

While it’s wise to limit screen time, this isn’t always possible — for instance, if you work with a computer, you’re likely to look at a screen on and off for eight or more hours. Give yourself short breaks with the 20-20-20 rule: Every 20 minutes, look away from the screen at something at least 20 feet away for 20 seconds.

Existing vision problems may exacerbate digital eye strain. If you have uncorrected nearsightedness or farsightedness, the eye’s muscles must work even harder to focus. Get an exam to ensure your contact lenses or glasses prescription is correct. Also, talk to your optometrist about getting glasses with anti-reflective coating. This reduces the reflections your eye picks up on the front and back of the lenses, which further impedes your ability to focus.
