I would not order again.  They are large enough that they rest on my nose more than other similar sunglasses.  The stems seem just a bit too short but they do grip my head snugly.  I wear them item over my prescription eyeglasses.  When I remove the sun glasses, my prescription eyeglasses come off too (unless I use 2 hands to remove the sun glasses).  Using two hands is not convenient, especially while driving.
