Good for plastic frames
I thought this were great for my son glasses to help keep them up on his face. They kept sliding down all the time. He had plastic framed glasses. Only this that was hard was trying to figure out how to use them at first. U don't get instruction on how to put them on so you have to kinds figure that out yourself. I could not get them to work on my daughter's frames which were wire.
