1pc Adjustable Anti-slip Eyewear Retainer Universal Fit Eyeglass Lanyard Sports Sunglasses Unisex Holder Strap Lanyard

I love it . it is well made but sometimes you forget that it's on and so you just have to remember to loosen it with adjusters before trying to remove your glasses.

With standard metal frames they are really hard to slide on. I stopped after a half inch or less. They are too short for my liking, the next size up would be better (+2") but still too short for me. In the same order I bought one that is like a fat shoelace that I really like. See pictures.

Excellent. A very smart, minimalist and no-fuss strap. It adjust securely to either keep your glasses snug on your face, or expands to let you hang them around your neck. I use them for my everyday glasses, as well as my cycling glasses. A smart solution. Highly recommended

It is bit small for me, I should have order something bigger size.
