How Blue Light Affects Your Eyes—and What You Can Do About It

According to The Vision Council, nearly 70% of Americans experience digital eye strain from spending long hours on phones, tablets, and computer screens.  If your eyes feel tired, dry, or blurry after a day of screen time, you're not alone—and blue light may be to blame.

What Is Blue Light?
Blue light is a high-energy, short-wavelength light on the visible spectrum (between 380–500 nanometers).  While it occurs naturally in sunlight—and even helps regulate your sleep cycle and boost alertness—it becomes a problem when you're exposed to it in large amounts from artificial sources like LED screens.

Over time, prolonged exposure to both UV light and blue light may contribute to eye discomfort and potentially long-term damage.   In today's world of constant connectivity, it's harder than ever to avoid.

The Problem: Digital Eye Strain
Spending hours in front of screens is now part of daily life, but our eyes weren’t built for that kind of nonstop focus.   The result?   A condition known as Computer Vision Syndrome, or digital eye strain.

Common symptoms include:
Eye fatigue or soreness
Blurred or double vision
Dry, irritated eyes
Headaches or trouble focusing

The American Optometric Association reports that between 50% and 90% of people who use digital screens regularly experience some of these symptoms.   If you're reading this on a screen, you might already be feeling the effects.
