Well, it seems that you like paying lacrosse quite a lot right? I find it really interesting sometimes. So, as you can see, on the lacrosse court, you will be seeing the ball flying around, and it seems to be quite dangerous to your glasses and eyes. Therefore, I suggest that you find an alternative to deal with your vision problem. Maybe you should try to get some contact lenses, which is quite convenient for you.
Well, in my opinion, you are not supposed to wear glasses when you play lacrosse. By wearing glasses, it is easy for them to slide off from your nose, and will be no convenient for your play. Also, if they are broken, it can hurt your eyes. So you should not wear the normal glasses. But on the other hand, you can just wear sports glasses like goggles. By wearing them, they have a strap to keep them on your eyes. so it will be comfortable to play. Also, I guess you can wear contact lenses too.
I don't think it is ok for you to wear the eyeglasses when you play lacrosse because the ball will fly on your eyes parts. You'd better wear the goggles especially for playing lacrosse which will help your eyes from getting damaged. You could also wear the contact lenses to help you see the vision and wear the transparent goggles to prevent from the flying ball.
