Blue light Spectral distribution

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
