Bloc Sunglasses

Sunglasses Question?
I just bought a two cheap pairs of sunglasses, but they are the bloc type (alien eyes), should I wear them, I know they help protect against the sun, but I don’t want people looking or laughing at me wearing them, they look basically like these here:

So should I wear them while I’m outside?
they not cobras, they drug store Glasses, but look pretty much the same
they are great..very sleek looking.
of course you should wear them.
