Hairstyles...I have a tall forehead and wear glasses!

If you want to shorten your face you need to create as many horizontal lines as possible--keep the bangs; you can change them if you hate them that much. Curling your hair all over might help too, but keep in mind that you want horizontal lines, not vertical, so get as much volume as possible (ok, don`t get a fro) and you`ll look much shorter

With a tall forehead - I think bangs are the way to go so I would be hesitant about getting rid of them. You could sweep the bangs slightly to one side. Maybe a shorter length (to the chin) would help. You could pin it under to see how it might look at that length.
