How Extended Computer Use Contributes to Digital Eye Strain and Dry Eye

In today’s digital age, most of us spend several hours a day staring at screens. While technology has made life more convenient, extended screen time can take a toll on your eyes. If you’ve ever experienced blurry vision, tired eyes, or a gritty sensation after a long day on your computer, you might be dealing with digital eye strain or even dry eye disease.
 

How Prolonged Screen Time Affects the Eyes

When you use a computer, tablet, or phone for extended periods, your eyes are constantly focusing and refocusing. This constant activity, especially at close range, puts stress on the eye muscles. Additionally, people tend to blink less when staring at screens - sometimes up to 60% less frequently. Blinking is essential because it spreads tears across the surface of the eye, keeping it moist and comfortable. Without frequent blinking, your eyes can become dry, irritated, and fatigued.
 

Understanding Computer Vision Syndrome

Computer Vision Syndrome (CVS), also known as digital eye strain, is a group of vision-related symptoms that result from prolonged use of digital devices. Common symptoms include:
 

• Blurry vision
• Eye fatigue
• Headaches
• Neck and shoulder pain
• Difficulty focusing

These symptoms can be worsened by poor lighting, improper screen positioning, and uncorrected vision issues.
 

The Link Between Digital Eye Strain and Dry Eye

Dry eye occurs when your eyes don't produce enough tears or when the tears evaporate too quickly. Screen time contributes to this by reducing blink rate, leading to inadequate tear distribution. Over time, this can disrupt the tear film and cause inflammation on the eye’s surface.
 

Symptoms of dry eye may include:
 

• Burning or stinging sensations
• A gritty or sandy feeling
• Redness
• Light sensitivity
• Fluctuating vision

If left untreated, chronic dry eye can damage the eye's surface and affect your overall visual comfort and quality of life.
 

Ways to Reduce Digital Eye Strain and Dry Eye

To protect your eyes while using digital devices, try the following:
 

• Follow the 20-20-20 rule: Every 20 minutes, take a 20-second break and look at something 20 feet away.
• Blink consciously: Make an effort to blink more frequently while working on screens.
• Adjust your screen: Position your monitor so that it's slightly below eye level and about an arm’s length away.
• Use artificial tears: Lubricating eye drops can help relieve dryness during screen use.
• Minimize glare: Use an anti-glare screen filter and ensure proper lighting in your workspace.
• Stay hydrated: Drinking plenty of water supports tear production.
