Chums Slim Retainer - Adjustable Eyewear Keeper - Thin Silicone Safety Eyewear Retainer for Women & Men

Perfect for excersize. Keeps glasses from falling down your nose. Looks cute.

Use these for loupes in surgery! And cute! Designs for vision sent me a plain black version, but they broke. This was my replacement!

I like the unit very much I've only used it for about 2 weeks that works very well I guess the only comment I'd have is it would be nice if it was just a little bit longer.

much better than the previous other brand I used.a bit tough to put on to my glasses at first.. but good news they don't slip off the back of the rims as often as my previous brand.May snip the back to separate the two sides if decide I don't need extra length.

Excelente

They work perfect my my loupes! They have enough stretch that they have some give when wearing them during a long work day in dentistry. Traditional ones with no stretch can be hard in the nose bridge.

My sister and I went to Water World in Denver and spent all day goofing off and getting some sun. There are tons of slides and we went in the wave pool and I did all that with my sunglasses on. Other people had to take theirs off and stick them in their swimsuits but my glasses were secured and they didn't slip at all. It's comfortable and the texture is soft. The tension ring is sturdy enough to keep the setting perfectly without moving except when you want it to. This stayed on my sunglasses without any movement whatsoever and it was extremely simple to install. I haven't yet found a negative with it. I will edit this if I find one.

Chums is known for quality gear.That said, these are little more than a plastic strap.Yes, they are silicone.But for $9.99?Way over-priced.
