Interesting. My only ailment right now is rapidly declining eyesight. Had 20/20 forever, then couple years ago was getting hard to read, so got some reading glasses cheap. Now I'm buying expensive prescriptions at a rate of every 6 months (3 times so far) with increasing strength, and it's annoying and worrying a bit. Can already feel the latest ones not doing as well as when I first got them. Randomly heard about some combination of red light and a screen (or pinhole glasses) from someone in a related field so got curious to look into that. Can't really find much on it though, so seems bogus.
