ABSTRACT:
Swim goggles have a pair of eye pieces, each eye piece having a lens with an essentially rigid peripheral frame. Each eye piece has a seal assembly which includes a seal holder and a seal gasket. The seal holder is secured to the frame and has a pair of spaced flanges extending in a direction generally away from the respective lens. Space between the flanges of the seal holder provides a groove extending around the eye piece and the seal holder is resiliently deformable but relatively stiff. The seal gasket is fitted within the space between the flanges and has an outer face standing clear of the flanges to contact the wearer's face. The seal gasket is resiliently deformable and softer than the seal holder to provide a secure but comfortable seal with the wearer's face. Selection of the relative resiliences of the seal holder and seal gasket permits accommodation to a wide variety of faces and extends use of the goggles. A swim mask with single lens provided with a seal assembly as above is an alternative.
