Your patients rely on their devices at home, work, school and everywhere in between. But the same technology that enhances their lives comes with a significant drawback – blue light. And your patients are taking in more of it than ever before.

At The Source

Blue light is emitted by a variety sources:

The Sun – Smartphones – Tablets – Computer Monitors – Televisions – CFL and LED Lighting

The Effect of Exposure


Visual Strain and Fatigue
With only three-percent blue cone photoreceptors, the eye struggles to adequately process this high-energy light. Additionally, blue light is myopically defocused in front of the retina, resulting in chromatic aberration. The constant effort to focus blue light results in visual strain and fatigue.

Digital Eye Strain
Digital eye strain has surpassed carpal tunnel syndrome and tendinitis as the leading computer-related workplace injury complaint in America. Symptoms such as dry eyes, tired eyes, and blurred vision can surface in as little as two hours of screen time.

"65% of Americans report experiencing symptoms of digital eye strain."
- The Vision Council
