I think they look pretty good! Glasses are actually a common fashion accessory these days (even so far as people who don't need them getting frames fitted with plain lenses), and this pair shows up just enough to say 'I'm not afraid to wear glasses', but without hiding the face behind them. And the purple says 'willing to go my own path'. Profesional and tasteful, but not old by any stretch of the imagination.

Get them fitted properly, and give them a little while. If you still hate them, take your prescription, measure your pupil distance, and go over to zennioptical and pick up something that you like more for cheap. Or just get different pairs to wear with different outfits.
