With a little adjustment of the strap. It kept my glasses on my face as they had a tendency to keep slipping forward. Perfect for what I needed

I'm really pleasantly surprised by how good a purchase it was. They do not slip off when put on glasses, and you can adjust the appropriate length.

Really good. They do what it says and have stopped my glasses always falling forward.Lots of colours in pack to interchange. Good price too

Very easy to use good quality, good adjustment

Excellent straps I’m very pleased.

Good choice of colours

Very good product for anyone who bends a lot , keep glasses very secure

They do the job ,just wish they were a bit longer
