Adjustable Glasses Straps - 3 Pcs No Tail Adjustable Eyewear Retainer Glasse Strap, Eyeglasses Straps, Sunglasses Straps

So I got these straps specifically for basic training, mainly because my civilian glasses kept slipping down and when we’re assigned the nerdy military glasses it’s required to wear straps. These straps are easy to put on, easy to adjust, comfortable to wear, but most importantly they’re virtually impossible to see. They also kept my glasses securely on my face through basic training and did the job admirably well. Pushups, PT, running, going up and down stairs, everything in between and the straps never raised issues. I actually still use them on my civilian glasses because they tend to slip down my face. 5 stars, love these.

Bueno.

I bought these to be able to wear my glasses on a roller coaster ride. I haven’t had a chance to test that yet. However, I’m now able to wear a pair of glasses that didn’t fit properly thanks to this strap. There are rubber ends that fit at the tips on the eyeglass arms. The strap is adjustable to the back of the head. I am pleased with this purchase.

I bought these for my 13 year old son, as he recently got his glasses accidentally kicked off in a taekwondo light sparring match. For times that he's not wearing his sparring helmet, these little guys come in handy. The one thing I will say is that they are a pain to get off once they're on your glasses, but I guess that's the point. You just got to kind of wiggle them around to get them off of the ends of the arms of your glasses.

I'm using these on sports glasses. The factory strap has been a problem since I got the glasses, but these substitutes are better than the factory straps... They don't fall or slip off. They have 1 job and they do it well..
