ABSTRACT:
An integrated field eyewear system of modular construction to permit adaptation to a wide range of wearers and operating conditions. A bridge includes a brow bar formed with slots for alternatively receiving left and right plano lenses or lens frames formed with openings for receiving snap-in corrective lenses. The plano lenses and lens frames are in turn formed with sockets for alternatively receiving either temples or anchors for receiving a headband. Sunshade or laser-protective secondary lenses may be snapped into place over the primary lenses to afford necessary protection. The front consisting of the bridge and the selected viewing elements may be fitted together with a removable goggle frame between the front and the wearer's face. To facilitate their use with lens frames of fixed dimensions, the corrective lenses are formed with bevels conforming to the surface of a sphere of constant radius, even for lenses of different front curvatures.
