90's BMW Eyeballs

Blue light is not the problem. Your squishy little eyeballs slowly hardening is the problem.

A more plausible reason why your eyes are getting tired is part of the aging process is your squishy little eyeballs get stiffer. Kind of like the interior of a ‘90’s BMW, slowly getting hard, you know, and then crumbling, right?

So your eyeballs get stiffer and that means it is harder to change the shape of your eyeball to change your focal distance. That means the muscles that do that have to work harder and so for a day of like your eyes going “Ah, I gotta squish this old 40 year old eyeball to focus on this screen, I’ve been doing it all day long, boy my eyes feel tired”…

I’m not an eye doctor, this is my vaguely plausible theory that makes more sense than blue light makes you tired.”
