Buy yourself a pair of sport glasses and tell your sparring partner to be fair and not to aim for the glasses. Tell her that you won't aim for her temple / eye region either.
Wearing contact lenses isn't a good idea.
You can do anything except spar. You can't use contact lenses. They irritate your eye when taking punches.
So yeah, you can practice boxing. Just no sparring.
If you want even better info. Talk to a doctor.
you have to take off your glasses while sparring. Im in martial arts and boxing wouldn't be any different with the punches and everything.
If you want genuine fights you'd require laser surgery (I can't remember if it's LASIK or LASEK sadly) and at your age you'd probably be advised against it. Your best option would be to practice without getting into spars (so hitting bags, mitts etc).
Can I box with glasses? I'm near sighted and I kinda have bad vision, I'm a girl, 15, and I really want to box, would I be able to wear contacts ?
