Filtration: The more you use digital devices, the greater the filtration of blue light that you will need. It is recommended that for those who use such devices more than four hours per day, a 40% or greater filtration level is desired.
Frames: The frames not only hold the lenses and create the style, but they also provide protection and longevity to your blue light glasses.
