HOW DO BLUE BLOCKING GLASSES WORK?

Blue light glasses work by reducing the amount of the blue light rays that will reach your retina cells at the back of your eye.

Different types of blue light glasses do this by either having a blue light filter coat or special blue light blocking lenses that are designed to reduce or block the blue and green light spectrum between 400nm - 550nm.

Blue light from digital devices is a hot topic right now with many companies offering their products to people who are serious about managing blue light for better health.

However, there are some special factors we feel are important for you to understand when looking to invest in a pair of blue light glasses from a brand.
