My husband wears regular eyeglasses and is constantly sliding them up his nose because they always kept sliding down.
I found these and decided it was worth a shot to try them. He loves them. They were fairly easy to put on. It took a little wiggling but easy enough. The grip is comfortable to wear, yet keeps them snugly in place so they no longer slide down his nose. He has put them on every pair of glasses and sunglasses he owns.
I would recomend these and would buy them again if we need more.
