Abstract

A lens for eyewear, the lens having a transmittance in a spectral range at least between 400 and 780 nm. The spectral range includes a first and a second color range which are different from each other. The first and second color ranges are each at least 50 nm broad. A first medium transmittance in the first range is higher than a second medium transmittance in the second range. A medium transmittance in the spectral range is above 35%. A maximum transmittance value in the spectral range is above 70%. The second medium transmittance is below 20%. A maximum value of transmittance within the second range is below 30%. The first medium transmittance is at least 15% higher than the second medium transmittance. Further, a method for providing a lens for eyewear for sports archery is provided. In particular, this may enhance visually targeting a sports archery target.

Abstract

The invention relates to a method of color-dyeing a lens for goggles and glasses (110), whereby said lens comprising a polycarbonate substrate (70-1), comprising the steps of: - providing (20, 30, 40, 50) a liquid mixture (50-3) of components comprising at least one dye (10-1, 10-2, 10-3) or pigment, suitable for color-dyeing polycarbonate and a dispersion medium (40-1), whereby said at least one dye (10-1, 10-2, 10-3) or pigment is dispersed as colloids in said dispersion medium (40-1); - immersing said polycarbonate substrate (70-1) into said mixture (50-3) such that said at least one dye (10-1, 10-2, 10-3) or pigment is impregnated into said polycarbonate substrate (70-1); and - withdrawing (90) said polycarbonate substrate (70-1) from said mixture (50-3). According to the invention the method is characterized in that said dispersion medium (40-1) comprising a solvent for dissolving said at least one dye (10-1, 10-2, 10-3) or pigment, whereby said solvent comprising at least one member selected from the group consisting of an organic alcohol, in particular an aromatic alcohol, in particular benzylic alcohol (10-4); a butyl acetate, and a methacrylate ester, in particular methyl methacrylate.

Abstract

Ski goggles for a goggles wearer having: a frame with a first side facing the face and a second side facing away from the face during normal use; a nose bridge for resting on the wearer's nose; a lens having a first surface facing the face and a second surface facing away from the face during normal use; a pad connected to the frame and resting on the face during normal use; a strap holding the goggles on the head during normal use; a coupling arrangement adapted to releasably couple the lens to the frame. The coupling arrangement includes a first coupling point at a nose area of the first side and a second coupling point disposed around at least a portion of a perimeter of the first side. The coupling arrangement includes the nose bridge. The bridge is releasably coupleable to the frame and provides the first coupling point.

Abstract

The invention is directed to ski goggles having a frame with a frame back side directed toward the wearer's face during use. A frame front lies opposite the frame back side and a frame edge is directed laterally outward with an upper frame-edge portion. A goggle lens is supported by the frame and a retaining strap, during normal use, holds the ski goggles on the wearer's head. A spoiler can be releasably connected to the upper frame-edge portion.
