WHAT IS BLUE LIGHT? The blue light on the visible light spectrum is very short in wavelength (380 - 500 nanometers) and has the highest energy among all visible light. It can be found in sunlight and is necessary for keeping us energetic and awake, also regulating our circadian rhythm. The issue arises though when blue light comes from artificial sources in large unwanted quantities. And the proliferation of electronics with screens, as well as energy-efficient lighting, is increasing the possibility of exposure to blue wavelengths, especially after sundown. WHAT DOES BLUE LIGHT DO TO YOUR EYES? The blue light goes deep into the back of the eye (further than UV rays), which can cause damage to the retina as time goes by— an important part of the eye that enables vision. The naked eye’s cornea and lens are unable to block this harmful light. That’s why the blue light blocking glasses become very important. WHY WEAR ANTI-BLUE LIGHT GLASSES？ Exposure to blue light for too long would lead to digital eye fatigue. Wearing our glasses, your eyes won't feel tired anymore. Reduce eye strain and sensitivity to light when facing digital screens. Just the right sort for office workers or anyone who has to look at a screen all day.
