Goggles include a frame unit having a main hole and a connecting portion, an adjustment set disposed on the frame unit, a first lens unit pivotally disposed on the frame unit, and a second lens unit having an engagement portion pivotally connected to the adjustment set. The adjustment set has an adjusting unit penetrating through the main hole, a positioning unit engaging with the adjusting unit, and a positioning hole formed on the positioning unit and adapted to engage with the engagement portion. Accordingly, the first lens unit can be lifted open at any angle relative to the frame unit. The upward and downward movement of the second lens unit is adjusted by the adjustment set, and a rotation of the engagement portion within the positioning hole allows the second lens unit to be lifted open at any angle relative to the frame unit.

The present disclosure discloses a goggle device and a spectacle frame thereof. The spectacle frame includes a buckling structure arranged on an end portion thereof. The buckling structure has an accommodating space and an entrance in spatial communication with the accommodating space. The buckling structure includes a cantilever arranged in the accommodating space and a retaining wall that is arranged in the accommodating space and is spaced apart from the cantilever. A free end portion of the cantilever is arranged adjacent to the entrance, and the cantilever is rotatable between a lock position and an unlock position. When the cantilever is at the lock position, the free end portion shields the entrance. When the cantilever is rotated to the unlock position by an external force, the free end portion does not shield the entrance, and the cantilever is deformed to store an elastic force.

A combined corrective lens engaged with a lens shield and method therefor is provided. The lens shield is formed of a first lens portion which is subsequently engaged with an independently formed projecting portion. One surface of the projecting portion is configured for grinding to a prescription lens. The combined lens can include light filtering medium or layers only in the projecting portion or in both the projecting portion and first lens portion since the components are formed in advance and joined.

A lens mount apparatus comprising a first lens component and a second lens component joined integrally with the first lens component, resulting in mechanochemical attachment of the second lens component with the first lens component to produce the unitary lens mount apparatus without compromising the lens mount apparatus optics, wherein at least one of the first and second lens components is an optical lens.

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.

The invention relates to eyeglasses having two lens units that are fitted with a device for keeping the eyeglasses on a wearer's head. The eyeglasses having a nose bridge that connects the two lens units and includes a central portion to be disposed about the wearer's nose At least one of the lens units has a duct inside to which a lateral portion of the nose bridge is slidingly mounted using a mechanism for adjusting the position of the lens unit relative to the nose bridge. The adjusting mechanism has a member that is rotatably mounted in the duct. The member and the lateral portion of the nose bridge comprise a coupler designed to convert the rotation of the member into a relative translational movement between the lateral portion and the duct.

A unitary lens structure is provided which is employable with spectacles as well as goggles and safety eyewear. The lens is formed as a unitary structure with projections having surfaces which are machinable for prescription eyewear extending from a first side surface of a larger shield. Damage from cracking of the shield at the intersections with the projection perimeters is prevented by non linear connections between the two surfaces.

Safety glasses having integrated correction lenses, wherein connecting means in the style of retaining frames are arranged in or on the safety glasses in order to accommodate the correction lenses, comprising adapter rings as compensating bodies between the curvature of the outer contour of the safety glasses and the curvature of the inserted correction lenses, wherein the correction lenses of different power are matched to the adapter rings in a uniformly accurately fitting manner at the periphery of the correction lenses in the curvature and shape of the correction lenses and different powers of correction lenses can be inserted into the adapter rings in the space between the safety glasses and the inner curvature of the adapter rings, wherein the adapter rings are thicker in the nasal region and taper temporally, approximately in a wedge shape.
