ABSTRACT:
A non-fogging goggle assembly comprises a transparent film of polyester or polycarbonate coated with a hydrophilic composition that lowers the surface tension of water droplets, causing them to spread rather than form vision-obstructing beads. The film is applied against the inner face of the goggle lens and releasably held in place without any adhesive by pressure-fitting the edge of the film or parts thereof into peripheral slots or grooves cut into the section of the frame surrounding the lens.
