Screen Time and Dry Eye: What You Need to Know

Screens play a major role in how we work, learn, and stay connected - but they can also take a toll on our eyes. With hours spent each day on computers, phones, and tablets, many people experience eye discomfort without realizing the cause. One of the most common issues linked to prolonged screen use is dry eye, a condition that can affect both comfort and visual clarity.

What Is Dry Eye?

Dry eye occurs when your eyes don’t produce enough tears, or when the tears evaporate too quickly. Tears are essential for maintaining eye comfort, clear vision, and overall eye health. When the tear film is disrupted, symptoms can develop, including:

• Burning or stinging sensations

• Gritty or sandy feeling in the eyes

• Redness

• Blurred or fluctuating vision

• Eye fatigue

While dry eye can affect anyone, prolonged screen use is a major contributing factor.

How Screen Time Contributes to Dry Eye

When using digital devices, 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 and helps prevent evaporation. Fewer blinks mean tears dry out faster.

Additionally, screen use often involves:

• Extended focus without breaks

• Wide-eyed staring, especially at higher screens

• Air-conditioned or heated environments, which dry out the air

Together, these factors increase tear evaporation and strain the ocular surface, leading to dry eye symptoms.

Practical Ways to Reduce Screen-Related Dry Eye

The good news is that small changes can make a big difference. Here are several effective strategies to help protect your eyes:

• Follow the 20-20-20 Rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds. This allows your eyes to relax and encourages normal blinking.

• Adjust Your Screen Setup: Position screens slightly below eye level so your eyelids cover more of the eye’s surface. Reduce screen glare and increase text size for easier viewing.

• Improve Your Environment: Use a humidifier to add moisture to the air, and avoid direct airflow from fans or vents toward your face.

• Use Artificial Tears: Preservative-free lubricating eye drops can help replenish moisture and relieve discomfort. Your eye care provider can recommend the best option for your needs.

When to See Your Eye Doctor

If dry eye symptoms continue despite lifestyle changes, it’s important to schedule an eye exam. Persistent dry eye can affect both your vision and overall quality of life if left untreated. An eye care professional can identify the underlying cause of your symptoms and recommend personalized treatment options, which may include prescription eye drops, in-office treatments such as LipiFlow®, and customized dry eye management plans designed to provide long-term relief.
