I used believe that they were for tossers too. Then I moved on to the idea of wearing them when it was hot, rather than just when it was sunny. Then I moved to Europe and realised that when the sun shines, the shades go on. Even if it's freezing. You only get one set of eyes, and you have to look after them.
You wouldn't not wear a condom because it looked silly.
PS Buy Ray Bans, because they're good.
