According to the American Academy of Ophthalmology the blue light from your smartphone is not making you go blind. The study is super sciencey so you should click the link in the tweet below if you want to learn more about it! It does say that the light is still messing with your sleep so if you use the night shift feature or try to stop using your phone a while before bed keep it up! If not, I don't either so no worries....except for potentially long term negative health consequences.
