WHAT IS BLUE LIGHT?
Remember learning about ROY G BIV in school? Red, orange, yellow, green, blue, indigo, and violet are the colors of the spectrum. Well, in recent years, a lot has been said about the effects of exposure to high-energy visible (HEV) blue light on vision and health, and it is finally being addressed.
Sunlight is a natural source of blue light, but computers, mobile, and other artificial light sources can emit high amounts of blue light.
WHAT ARE THE EFFECTS OF OVEREXPOSURE TO BLUE LIGHT?
At its most basic, blue light is often referred to as visual noise. Due to environmental factors or the condition of the eye, blue light will scatter and not easily come to focus on the retina. This often makes for less than comfortable viewing.
More critically, some wavelengths of blue light have now been identified to be possible risk factors for age-related macular degeneration, which can lead to vision loss. Also, exposure to some blue light will affect sleep/wake cycles, resulting in not being able to fall asleep easily.
Due to both the increased amount of time spent using these devices and the close proximity of the devices to our eyes, there is growing concern about the effects on our eye health.
HOW TO BEST PROTECT OUR EYES FROM HARMFUL BLUE LIGHT
Although blue light is certainly everywhere, the exposure to blue light has increased significantly with the use of electronic devices – phones, tablets, computers. If you are a regular user of any of these, you should seriously consider blue light protection. Cosmetically, the lenses are virtually clear, and functionally, they are a very smart choice. Blue light blocking lenses not only help prevent eye damage, but also improve comfort when using digital devices.
Fun fact: High-energy visible (HEV) light rays make the sky look blue.
