Digital Screens & Eye Strain: How to Protect Your Vision in the Modern World

From smartphones and tablets to laptops and TVs, digital screens are part of nearly every moment of modern life.

But with this constant exposure comes a growing problem — digital eye strain, also known as computer vision syndrome.

What Is Digital Eye Strain?

Digital eye strain occurs when your eyes become fatigued from prolonged use of screens. The average person spends over 7 hours per day in front of digital devices — often without realizing how hard their eyes are working.

Common symptoms include:

Blurred or double vision

Dry, irritated eyes

Headaches or neck pain

Difficulty focusing on distant objects

Eye fatigue or heaviness

If you recognize these signs, it’s time to rethink your daily screen habits and visit your local optometrist in Aurora or Newmarket for a comprehensive eye exam.

Why Digital Devices Affect Your Eyes

Your eyes must constantly focus and refocus while looking at screens — especially small ones like phones and tablets.

Blue light emitted by these devices adds to the strain by scattering more easily, making it harder for your eyes to maintain sharp focus.

Other contributing factors include:

Poor lighting (too bright or dim)

Improper screen distance or viewing angles

Reduced blinking while staring at screens

Uncorrected vision problems such as astigmatism or presbyopia

Over time, these factors can lead to chronic discomfort, sleep disruption, and even long-term vision fatigue.

How to Reduce Digital Eye Strain

1. Follow the 20-20-20 Rule

Every 20 minutes, look away from your screen and focus on something 20 feet away for at least 20 seconds.

This quick break relaxes your eye muscles and prevents fatigue.

2. Adjust Screen Settings

Reduce brightness to match room lighting.

Use night mode or blue light filters after sunset.

Increase text size for easier reading.

These small adjustments make a big difference over long screen sessions.

3. Blink More Often

Blinking naturally refreshes your eyes and prevents dryness. When using digital devices, people blink up to 60% less frequently, leading to irritation and blurred vision.

Keep artificial tears or lubricating drops nearby if you notice dryness.

4. Optimize Your Workspace

Set your screen about an arm’s length away and slightly below eye level.

Adjust your chair height and desk setup to promote good posture — reducing strain on both your eyes and neck.

5. Use Blue Light Glasses or Lenses

At Parham Optical, we offer blue light blocking lenses that filter out harmful wavelengths emitted by digital screens.

These lenses help reduce glare, improve focus, and support better sleep quality by minimizing exposure to blue light during evening hours.

6. Schedule Regular Eye Exams

Even minor prescription changes can worsen digital strain.

Our Aurora and Newmarket optometrists perform precise refraction tests and recommend lens coatings that make screen use easier on your eyes.

How Blue Light Impacts Sleep and Health

Blue light affects your circadian rhythm, which regulates sleep. Exposure to blue light from screens — especially at night — suppresses melatonin production, making it harder to fall asleep.

That’s why blue light filtering lenses and screen-time management are so important for people who work late or use devices before bed.

Reducing blue light not only protects your eyes but also promotes better rest and overall health.
