<p>Swim goggles 10 have a pair of eye pieces 11,12, each eye piece having a lens 17 with an essentially rigid peripheral frame 18. Each eye piece has a seal assembly 23 which includes a seal holder 28 and a seal gasket 30. The seal holder 28 is secured to the frame 18 and has a pair of spaced flanges 41,42 extending in a direction generally away from the respective lens 17. Space between the flanges of the seal holder provides a groove 58 extending around the eye piece and the seal holder is resiliently deformable but relatively stiff. The seal gasket 30 is fitted within the groove between the flanges 41,42 and has an outer face 60 standing clear of the flanges to contact the wearer's face. The seal gasket 30 is resiliently deformable and softer than the seal holder 28 to provide a secure but comfortable seal with the wearer's face. Selection of the relative resiliences of the seal holder 28 and seal gasket 30 permits accommodation to a wide variety of faces and extends use of the goggles. A face mask with a single lens provided with a seal assembly as above is an alternative.</p> |
