Adjustable Glasses Straps,3PCS Sports Glasses Strap, Adjustable Eyewear Retainer,Glasses Holder, Suitable for Men's Glasses, Women's Glasses, Children's Glasses, and Sunglasses (black).

I love these straps. They are adjustable so will fit different head sizes. They do not make a long strap that will hang around your neck. They also do not force the glasses tight around your face.When you put the strap on the glasses you have to then put the strap over your head, that part is a little awkward but once they are on, the strap sits loosely around the nape of your neck. Unless you choose to tighten it up of course. I like that it came with many of them because they are easy to misplace. I used mine when I went to an amusement park where I had previously lost my glasses on a ride. I was thrilled to not lose them again.

Got these for the whole family and they work very well. Not easily seen either which is a plus for the younger gen in the family.
