‘Venetian Blinds’ in Goggles Shade the Wearer’s Eyes (Mar, 1941)
‘Venetian Blinds’ in Goggles Shade the Wearer’s Eyes
Tiny Venetian blinds are built into the top of a new type of sun goggles to shade the eyes from direct sun glare. The Venetian-like structure is an integral part of the lenses, formed by deep rectangular indentations in the lens material which are then filled with opaque liquid. While the uncolored lenses are about ninety-eight per cent transparent, the upper part intercepts overhead sun rays and casts a shadow on the eyes. In one type, the “blinds” are made of thin, flat wires.
