An ophthalmic device for use, in particular, in vigorous sporting activities, comprises a pair of lenses (11) mounted in a frame front (10), and held in position on the wearer's face by an adjustable flexible band (18). The band (18) is secured to the frame front (10) by lugs (16 L & R), mounted inside the frame front and perpendicular to the plane of the lenses (11). These lugs (16) are in horizontal alignment with a nasion protrusion (14) that is integral to a nose rest piece (12). The nose rest piece (12) is of a flexible material and is secured between the lenses (11) at the bridge area of the frame front (10). These glasses cannot fall from the wearer's face, and provide a no-slip, no-pitch, no-yaw fit. The glasses are extremely comfortable to wear for long periods of time. |
