Proprietary Floating Lens™ design offers increased flexibilty to fit more wearers. Secure wraparound brow expands to fit a wide range of users. The cushioned temple ends ensure gentle contact behind the ear, the spot that is usually most sensitive for spectacle wearers. Soft flexible "fingers" on the nosepiece reduce slippage.
