A user may easily replace lenses in the protective goggles. The frame body is compositely made with a rigid frame member and a resilient frame member. An outer circumferential area of a replaceable lens abuts against the resilient frame member and also engages with the rigid frame member so as to be fixed together. The resilient frame member guarantees fluid-tightness (water-tightness or air-tightness) of the goggles and dispenses with a packing and the like.

Protective goggles

Uncut spectacle lenses and a pair of spectacles using such lenses are provided. The uncut lenses includes a lens body and a pair of tabs fixed to an outer periphery of the lens body in opposite relationship with each other with respect to the geometrical center of the lens. The optical center of the lens is set up at a position spaced apart from the geometrical center thereof such that a line connecting the geometrical center and the optical center of the lens makes a predetermined angle with respect to a central line passing through the pair of tabs and the geometrical center of the lens. Further, the invention provides a polarizing spectacle lens wherein the optical center of the lens is located at a position spaced apart from the geometrical center and the line connecting the geometrical center and the optical center makes a predetermined angle with respect to the axis of polarization of the lens.

Goggles enabling fine adjustments of eyecups and providing an increased degree of fitting freedom onto wearer's face are provided including a pair of right and left eyecups, a nasal belt interconnecting respective opposing inner end portions of the eyecups, and an elastic band connecting to respective outer end portions of the eyecups, each of the outer end portions of the eyecups defining a band insertion hole vertically extending therethrough.

Goggles having vertical band insertion holes

Goggles allowing their eyecups and nasal belt to be adaptable to vertical movements and providing an increased degree of fitting freedom onto wearer's face are provided including a pair of right and left eyecups, a nasal belt interconnecting respective opposing inner end portions of the eyecups, and an elastic band connecting to respective outer end portions of the eyecups, the connection between each of the eyecups and the nasal belt being achieved by a stick-like projection having a substantially circular cross sectional configuration and a projection engaging hole in which the stick-like projection is rotatably fitted.
