CliC Expandable Readers go on and off easily with the unique patented magnetic system that allows the glasses to come together at the bridge. The head band is form-fitting and wraps around your head to ensure a snug, comfortable fit. They are also virtually unbreakable.
Putting them on is simple. Just place the band around your head and let the magnets draw together at the bridge. Want to take them off? No problem. Just pull the magnets apart and the glasses will hang comfortably around your neck. You'll never misplace your readers again.
And for those individuals with wider heads the Expandable-wide bends out more, and has expandable back as well to accommodate a wider head.
