The CliC XXL reader is the largest frame CliC makes. It is wider, longer, and adjustable not only on the sides but also in the back of the headband. The firm headband lets the glasses rest around your neck when not in use, and helps keep them in place when in use. To wear, simply lift the glasses up over your nose and the powerful magnet between the lenses simply “clics” into place. Never lose your glasses again!
