Protecting Your Eyes from Blue Light in the Digital Age

We live in a world surrounded by digital screens—phones, tablets, laptops, and TVs. While these devices make life easier, they also expose our eyes to blue light, which may contribute to eye strain and disrupt sleep patterns.

What Is Blue Light?
Blue light is a type of high-energy visible (HEV) light that comes from both natural sunlight and digital devices. Because it penetrates deeper into the eye, prolonged exposure can cause fatigue and discomfort.

Common Symptoms of Blue Light Exposure

• Tired or burning eyes

• Blurry vision

• Headaches

• Difficulty falling asleep

How to Protect Your Eyes

1. Follow the 20-20-20 Rule: Every 20 minutes, look at something 20 feet away for 20 seconds.

2. Use Blue Light Filters: Many devices now have built-in “night mode” or filter settings.

3. Wear Computer Glasses: Special lenses can block harmful blue light.

4. Limit Screen Time Before Bed: Reducing screen exposure an hour before sleep may improve rest.

Final Thoughts
Digital devices aren’t going away anytime soon—but with small adjustments, you can protect your eyes and reduce discomfort. Regular eye exams are also essential to make sure your vision stays healthy in the long run.
