How can eyeglasses not fall in basketball?


In anime basketball such as [Slam
Dunk](http://en.wikipedia.org/wiki/Slam_Dunk_%28manga%29), [Dear
Boys](http://en.wikipedia.org/wiki/Dear_Boys#Characters) and [Kuroko's
Basketball](http://en.wikipedia.org/wiki/Kuroko_no_basket), most of the
characters with eyeglasses, play basketball without having their eyeglasses
fall or broken during the game. How can this happen?




In real life, people that wear glasses often wear "sports bands" when they are
concerned about their glasses flying away during athletic events. However,
well fit glasses don't need any additional enhancements as long as the athlete
isn't performing many rolls. Simple jumps are not enough to cause well fitting
glasses to fall or fly away in this case.

In addition to that, some glasses have highly curved end pieces to help secure
glasses on the wearer. These end pieces wrap further around the ears than
simple straight pieces, and this helps keep the glasses secure.
