The Link Between Screen Time and Dry Eyes

In today's digital world, screens are everywhere—computers, smartphones, tablets, and televisions play a significant role in our daily lives. While these devices offer convenience and connectivity, prolonged screen time has been linked to an increase in dry eye symptoms. Understanding how digital screens impact eye health and what you can do to protect your vision is essential.

How Screen Time Contributes to Dry Eyes

When staring at a screen, people tend to blink less frequently—sometimes up to 50% less than normal. Blinking is crucial because it spreads tears evenly across the surface of the eye, keeping it lubricated. A lower blink rate can lead to increased tear evaporation and discomfort.

Most digital screens are positioned straight ahead or slightly below eye level. When the eyes are open wider for extended periods, more tears evaporate, leading to dryness and irritation.

Screens emit blue light, which can also contribute to digital eye strain. While blue light itself does not directly cause dry eye syndrome, prolonged exposure can lead to discomfort, making symptoms of dryness and irritation worse.

Common Symptoms of Screen-Induced Dry Eye

People experiencing screen-related dry eye symptoms may notice:

•          A gritty or burning sensation in the eyes

•          Redness and irritation

•          Sensitivity to light

•          Blurry vision after prolonged screen use

•          Excessive tearing as the eyes overcompensate for dryness

How to Protect Your Eyes from Screen-Induced Dryness

•       Follow the 20-20-20 Rule: To reduce eye strain and dryness, follow the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away. This helps relax your eye muscles and encourages blinking.

•       Adjust Your Screen Position: Position your screen slightly below eye level to reduce the width of your eyelid opening, minimizing tear evaporation. Keeping the screen at a comfortable distance also reduces strain.

•       Use Artificial Tears: Over-the-counter lubricating eye drops can help maintain moisture levels in your eyes. Look for preservative-free options to avoid irritation with frequent use.

•       Blink More Often: Make a conscious effort to blink fully and frequently while working on a screen. This helps spread tears evenly and prevents them from evaporating too quickly.

•       Optimize Your Environment: Use a humidifier to add moisture to the air, especially in dry indoor environments. Adjusting your screen brightness and contrast settings can also help reduce eye strain.

When to See an Eye Doctor

If you experience persistent dry eye symptoms, it’s important to see an eye doctor. An optometrist can assess your tear film, check for underlying conditions, and recommend treatments such as prescription eye drops, or punctal plugs to improve tear stability and relieve discomfort.
