I got these for my husband and in general he likes them, except when he leans his head back against a chair or a pillow, then the pressure pushes the glasses forward, making them fall down his nose and go all crooked  . As long as he uses them not laying down or resting his head against something, they're good. He likes them. He wishes that 1) I got him 2.0's instead of 1.75 and 2) that  the back-of-the-head strap was soft instead of rigid.<br /><br />A.
