Don't buy this if you wear glasses all day long.
This is NOT a long-term solution to the slipping eyeglasses syndrome. I bought this product for a pair of prescription glasses I use every day and only remove at bedtime. The temples for this aged pair of glasses are too short and don't hook around my ears as they should. The EWIN ear-hooks worked fine for at least three weeks. They were comfortable and kept the eyeglass frames from slipping off my nose and falling off during exercise. Unfortunately, after a time the silicone rubberized material breaks down to the point that the ear-hooks become distorted (almost &#34;melting&#34; from constant use) and eventually they lose their grip on the glasses and become useless. I even tried washing them with mild soap and water, thinking that the natural oils in my skin were the culprit, but that proved to be just a temporary solution. After experiencing similar results with the other five pairs of ear-hooks, I gave up and went back to wearing my tried-and-true Croakies (an adjustable nylon lanyard with rubber &#34;soda straw&#34;-type hold-fasts). Although they make me look like an aged librarian and are a bit clunky to put on and take off, at least I won't be dropping my expensive eyeglasses.
