Abstract: This invention relates to an optical filter for use in eyewear such as ski googles, as well as eyewear using the filter. For improving visibility in snow dominated locations, the filter has a transmission spectrum having a first transmission peak in the wavelength range of 620 nm-670, with a maximum at approximately 650 nm.

Abstract: A ski goggles with detachable lens comprises a frame constituted by a lens bedding part (1) for receiving lens (3) and being attached to a soft polymer frame part (2), so as to work as one piece. A lens panel is defined and laminated between the outer lens and the inner lens. Magnets are provided in the lens bedding (1) for automatic and correct location of the lens (3). A tab (4) with polymer spring is provided centrally on the lens panel, which is received by a locking lever (5) located on the lens bedding part (1) for locking the lens. The magnets are adapted to locate the lens (3) on the lens bedding part (1) such that when the locking lever (5) is released, the lens protrude out of the frame keeping a reasonable gap from the frame.

Abstract: A description is given of a ski sledge having a swiveling front ski (1) with steering means (6), two essentially mutually parallel rear skis (2, 3) and a seat (4) connected via one or more rods (7) to the steering means, where the rear skis (2, 3) are connected to the sledge by means of a parallelogram arrangement.
