Eyekepper glasses will give you the premium protection you are looking for If you are unfamiliar with blue light it's right next to UV light on the spectrum of light. It is comprised of very high energy and a low wavelength very similarly to UV light. All of our electronic devices with a back-lit screen give off large quantities of blue light (Iphones, Ipod, Laptop, Computer TV.) This blue light messes with our internal clock making us think it's mid day when really it can be closer to night and stops our body from naturally producing the melanin that helps us fall asleep late at night CARE To avoid damage, never clean your computer glasses with paper towels or clothing or alcohol, and also avoid using household detergents or soaps. While a few mild soaps don't harm lenses, today's extra strength soaps are powerful enough to slowly disintegrate lens coatings.
