How To Choose A Pair of Eyeglasses So Good, You’ll Forget You’re Wearing Them

With sun being the primary source of harmful blue light, long hours spent on the computer also expose us to blue light that can be potentially harmful to our eyes and overall health. These blue light exposures can also lead to discomfort and a disrupted sleep schedule, depending on the range of the blue light source. 

“Blue light is the light spectrum between 400nm and 500nm, and unlike ultraviolet light, blue light is visible light and necessary for human functioning. But too much exposure to certain blue light wavelengths may cause eye strain,” says Hively.

The good news is that you can reduce your exposure to blue light. LensCrafters offers prescription Blue IQ blue-light-filtering lenses that help reduce your exposure to blue light from natural and artificial sources. These lenses can filter at least 20% of blue light. Additionally, you can change the brightness of your screens to reduce light and perform the 20-20-20 Rule—every 20 minutes take a 20-second break and look at something 20 feet away.
