Amaxiu8 Pack Kids Eyeglasses Straps with 8 Pair Ear Grip Hooks, Silicone Anti Slip Sunglasses Holder Elastic Eyewear Retainer Glasses Band Holder Eyeglass String Strap for Sports Kids

I honestly wasn't sure these would do any good but as I have one bespectacled child who enjoys martial arts, I thought I'd give these a bash and see if the help with stopping his glasses from going flying every time he launches himself into space (also known as a forward roll with excessive force, for some bizarre reason).Initially, I thought these straps would be far too small as they seem tiny when you take them out of the bag and don't appear to stretch all that much. However, upon slotting them into place, they were indeed long enough and not too tight either.They are easy to fix - just push the ends of the glasses into the holes and slide up until you're happy with the placement. It's far easier to do one side first, pop your glasses on and then slot in the other side - the alternative is trying to stretch it over your head and not impale yourself in the eyeballs with your glasses. I mean, totally up to you...So far no issues but I do wonder whether the stretchiness will give out eventually or snap with overuse. But at the moment, a happy customer.
