Before technology became mainstream the only light available to man came from the sun, apart from the light the from the evening fire or candle light. We would wake up at sunrise and retire to sleep at sunset.
But we now live in a world where there is so much artificial light. We are exposed to light both indoors and outdoors. Digital devices today use special LED lights that emit a powerful form of light called Blue Light.
Light is comprised of electromagnetic particles that movement in waves. These waves produce energy, and range long and quality. The shorter the wavelength; the higher the energy. The length of the waves is estimated in nanometers (nm), with 1 nanometer rising to 1 billionth of a meter. Each wavelength is spoken to by an alternate shading, and is gathered into the accompanying classes: gamma beams, x-beams, bright (UV) beams, visible light, infrared light, and radio waves. Together these wavelengths make up the electromagnetic range.
However the human eye is touchy to just a single piece of this range: visible light. Visible light is that piece of the electromagnetic range that is viewed as hues: violet, indigo, blue, green, yellow, orange and red. Blue light has a short wavelength, thus creates a higher measure of energy. Studies recommend that, after some time, introduction to the blue end of the light range could cause genuine long haul damage to your eyes.
Blue light waves are the among the most limited, highest energy wavelengths in the visible light range. Since they are shorter, these “Blue” or High Energy Visible (HEV) wavelengths glint more effortlessly than longer, weaker wavelengths. This sort of glinting makes a glare that can diminish visual differentiation and influence sharpness and clearness.
This glimmering and glaring might be one reason for eyestrain, migraines, physical and mental weakness caused by numerous hours sitting before a PC screen or other electronic gadget.
Our eyes’ normal channels don’t give adequate security against blue light beams from the sun, not to mention the blue light exuding from these gadgets or from blue light produced from bright light tubes. Drawn out presentation to blue light may make retinal damage and contribute age-related macular degeneration, which can prompt loss of vision.
To protect your eyes from the dangers of Blue Light we recommend you invest in blue light blocking glasses.
