Help! Where to Buy Eyeglasses in L.A.

I need new eye glasses. I do not know where to find eye glasses in Los Angeles. Can you help?

The criteria: Glasses must be, y’know, kinda cool. Glasses must not be weird in a way that would make a stranger feel the need to come up to me and comment on the glasses. Glasses should probably be brown or black. Glasses could be classified as something that a, oh i dunno, stereotypically hip let’s say librarian would wear.

Thanks!
