WHAT IS BLUE LIGHT?
There is natural light, which contains red, orange, yellow, green and blue light rays in many shades of these colours, depending on the energy and wavelength of the individual rays. Combined, this spectrum of coloured light rays creates what is generally called sunlight.
Blue light rays have the shortest wavelengths (and highest energy) and is sometimes called blue-violet or violet light. This is why the invisible electromagnetic rays just beyond the visible light spectrum are called ultraviolet (UV) radiation.
The average person spends up to 5 hours a day online, behind a computer, tablet, T.V or phone. This can cause headaches, eyestrain and disrupt your sleep.
Our Blue Light Blocking glasses can help filter out the blue-violet by up to 50%. Therefore it can help with dry eyes, headaches and even quality of sleep.
