You shouldn't feel the need to show off your intelligence based on what glasses your wearing; you're just inviting people to make a preconceived judgement of you. I've been really into the more thicker rimmed glasses because they seem to be in style right now, but thinner, metal frame glasses could probably work for just about anybody, It's up to you really what you want to look like, and even then looks don't really matter that much at the end of the day!
