Blue light is found everywhere, from the sun to TV’s, Smartphones, computers etc.
The major concern is the way this light effects our eyes. Blue light is a visible color on the light spectrum scale that produces higher amounts of energy because it is a shorter wavelength. Blue light penetrates directly to the retina and too much exposure can damage the light – sensitive cells in our eyes.
Damaging these cells can cause eyestrain, fatigue, headaches and sleeplessness. Here are a few helpful tips to decrease your blue light exposure: wear blue light filter glasses, blink more often when staring at a digital screen, take frequent breaks when staring at electronic devices, use warmer colors on TVs and monitors to reduce eye strain.
