What the Heck Are Blue Light Glasses?
There’s a good chance those sleepless nights, tired eyes and headaches are related to a surge in screen time during COVID-19. Read on to learn how blue light glasses could be the solution.
Before addressing the concerns of blue light, let’s identify what it is. Blue light is a color in the “visible light spectrum” that can be seen by the human eye. It falls between harmful UV light, which is not visible to the human eye, and beneficial light, that which is visible to the human eye. And while blue light is found everywhere, it’s specifically found in digital screens as well as LED and fluorescent lighting.
As we spend more and more of our time at home in front of screens – phones, tablets, computers, iPads, televisions – it’s important to address what this is doing to our eyes and vision. Excessive exposure to blue light can cause fatigue, eye strain, headaches and sleeplessness.
Blue light-blocking lenses can help combat these negative effects. Here are two things to know when selecting blue light lenses:
Götti Switzerland, style Gabor VI
1. Lightly tinted lenses
These lenses are coated with a built in, light yellow filter to block more of the blue light spectrum, and offer the most protection against retinal damage, digital eye strain, and sleep interruption.
XIT, style V307
2. Virtually clear lenses
These lenses filter just the HEV damaging portion of the blue spectrum.
With each type of material there are customizable lens designs available to fulfill specific needs for everyday wear, computer, driving or sports. Blue light lenses can go in any eyeglass frame, however, the stronger the vision correction, the yellower the lenses will appear.
