What is blue light?
Blue light is part of the visible light spectrum (what the human eye can see). It has the shortest wavelength and highest energy, vibrating within the 380 to 500 nanometer range. About one-third of all visible light is considered blue light. Blue light boosts alertness, helps memory and brain function, elevates mood, and regulates your body's circadian rhythm.
Sunlight is the biggest source of blue light. Artificial sources of blue light include fluorescent light, LED TVs, computer monitors, smartphones, and tablet screens.
Why protect yourself?
In our digital age, our daily exposure to blue light emitted by screens and artificial light sources is constantly increasing. The adverse effects of this exposure on our visual health are well documented. High-energy blue light can disrupt our sleep, cause eye fatigue, headaches and potentially contribute to long-term visual problems. With the constant use of smartphones, computers and other digital devices, our exposure to blue light has become ubiquitous.
What is ocular fatigue?
It's a combination of blurred vision, dry and irritated eyes, headaches, neck and back pain. Screen-related eye strain has overtaken carpal tunnel syndrome as the leading source of discomfort while working on a computer.
