Glasses Holder
 

Had a game last week and one of the girls was wearing glasses and had a cloth holder that kept the glasses on her head. The cloth went around the back of her head and had a small bead where the two ends met, kind of the tightener if you will. I allowed it but don't feel good about it. Is there anything in the rules about this type of device, my guess is its legal without the bead. She had long hair and it was mostly concealed by her mop of hair, but so are some earrings concealed by hair (even Mark's) and of course they're not legal.

A strap holding glasses is legal, and has no restrictions in terms of color.

All you needed to do was determine if it was safe. If you believe it to be unsafe, she can't play with it. If it's safe, she can. Judgement, my friend.
