All CliC eyewear offers the patented magnetic front connection, adjustable temples, and permanent headband features. Our rigid headband style is ready to withstand even the roughest (and most careless) behaviors because CliC glasses are made with incredibly durable material. So go ahead, toss them in your brief case, throw them in your toolbox - when you put them back on, they'll return to their original shape and provide you with the comfortable fit you expect. WHAT MAKES CliC'S UNIQUE? The unique magic begins with our convenient magnetic front. This patented technology makes for an easy on, easy off motion. The adjustable temples provides flexibility to find a perfect fit. No one is a one-size-fits-all type of person and neither are CliCs. This is the original frame size which is great for people requiring a smaller fit. The side stems are adjustable for a proper fit. IS THIS MODEL THE BEST FIT FOR ME? Each model listed has a photo with the dimensions of the glasses. Make sure that the photo is for the model that interests you and review the dimensions to ensure that model is the best fit for you.
