It really irks me but why are glasses on people used to depict weakness? Which I think effects how attractive people are viewed for dating?

I grew up seeing this represented in TV, books, comics and movies. I thought it had gotten better but I am still seeing this stereotype! Some examples... in Spiderman he is this needy weak kid with glasses. Gets his superpowers and boom. Bye bye glasses. I know it makes sense that he now has good vision but still. With Superman... glasses make him generally unattractive and nerdy to hide as Clatk. Remove glasses. Boom. Sexy strong powerful Superman. In anime, I'm watching Blue Exorcist and the "demon" strong brother no glasses. His "weakling" powerless brother... glasses. I could go on. I think only character who goes against this stereotype is Harry Potter cos he becomes a hero strong character and retains wearing his glasses. (J. k Rowling is awesome at this.)
