Digital devices that emit the highest amounts of blue light can be on your laptop, computer, smartphone, or e Reader like a kindle, exposing the delicate tissues of the eyes.

The naked eyeâs cornea and lens are unable to block this harmful light, which is where blue light glasses become very convenient.
