POTENTIAL EFFECTS OF BLUE LIGHT
Exposure to artificial blue light could cause all kinds of problems, including dry eyes to digital eye strain, sleep cycle disruption, and even macular degeneration.
Digital devices fit so naturally into our daily lives that it’s easy to forget how “unnatural” it is for our eyes to work, read and play from a digital display for hours. Back lit displays expose us to higher than normal amounts of blue light which can cause digital eye strain, fatigue and sometimes permanent damage to your eyesight.
WHAT IS BLUE LIGHT?**
Natural blue light is all around us. It’s what makes the sky look blue. Natural blue light regulates your sleep and wake cycles. It also boosts alertness, elevates your mood, and increases feelings of well-being. Artificial blue light, found in things like computers and flat-screen televisions, LED lights and energy-efficient light bulbs, can be harmful to your eyes. The backlit displays on cell phones, e-readers, and laptop computers emit high amounts of very strong blue light waves. Too much blue light can take a toll on your health.
Within the visible light spectrum, blue light has a shorter wavelength and higher energy, which is harder for our eyes. Because these waves are shorter, they appear to flicker more than longer, weaker wavelengths. Flickering is the flashing effect that happens when the LED backlight controller of a monitor adjusts the brightness levels during display refreshing. This causes eye fatigue without you even noticing. Take a look at the light spectrum to see how blue light works.
BLUE LIGHT OVEREXPOSURE AND AGING**
A Harvard medical study states that “High Energy Visible (HEV) blue light has been identified for years as the most dangerous light for the retina. After chronic exposure, one can expect to see long-range growth in the number of eye diseases including macular degenerations, glaucomas, and retinal degenerative diseases.”
