10 Pack Silicone Anti-slip Eyeglass Strap Eyewear Retainers Sports Ear Hook Sunglass Cord Holder

Bought this for my 6 year old as his glasses kept on sliding down his nose bridge. However since using this he doesn't have that problem anymore. He enjoys changing the colours each day, and finds it very comfortable to wear all day.The strap doesn't fit very tightly, but instead gently rests on the hair just above the back of his neck, and this seems to be enough to keep his glasses in place. This also means there is no pressure on the back of his head like I first thought, making it very comfortable to wear.Great solution to a simple problem and great product.
