The unexplainable success of a mundane piece of content
I use my elbows to push my glasses up.
I have many, many times wished for an Optigrab.
I'm in camp 4, for the reasons left in one of the comments. I have expensive glasses frames and want to keep them around for a long time.
there's also not using the hands...i jerk my head back and the glasses fall back up my nose, sometimes (it's an inferior method); or using the back of your wrist if you are doing something like cooking.
there is a product that makes it so you don't have to push your glasses back up in place--it's a small silicone extra glasses arm that slides onto/shortens your glasses arms to tuck them properly behind your ears.
