Some of the gymnasts choose to take off their glasses for gymnastics practice, if their number for their glasses isn't too high and they are stll comfortable without glasses. The young boys and girls that need their glasses on use the bands on their glasses to keep it on. But if you can wear contact lenses and are old enough for them, etc. it is much easier than glasses especially for gymnastics. Soft lenses are good, chalk or dust that goes into them is kind of just like if it goes in your eyes if you're not wearing contact lenses.
