I have both but prefer my contacts! I wear them about 99 percent of the time....I use my glasses only when I am being lazy and just chilling out at home or before bed. I have had to wear glasses/contacts since I was very young and started out with the most uncomfortable "hard contacts" which they don't make any more. That should give you a clue at how old I am....Lol! I hate wearing glasses in the summer because they always get yucky when I am sweaty from the summer heat....and fog up in the winter!
I would go with both....contacts w/glasses for a backup!
