Eyeglasses Anti Blue Light Blocking Optical - Unisex Designer Computer Glasses.

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.

This piece is also trendy and can be  a gift to your loved one.
