Half Frame Reading Glasses Blue Light Blocking Glasses - With Free Case

Digital devices that emit the highest amounts of blue light can be on your laptop, computer, smartphone, or eReader like a kindle, exposing the delicate tissues of the eyes. Blue light reaches deep into the back of the eye (further than UV rays), which over time can cause damage to the retina — an important part of the eye that enables vision. The naked eye’s cornea and lens are unable to block this harmful light, which is where blue light glasses become very convenient.
