An eyeglass lens () includes a polarizing part () and a non-polarizing part (). The polarizing part () includes a base part () and a polarizing sheet (). The non-polarizing part () is adjacent to the polarizing part (). The polarizing sheet () is in face contact with the base part () in a non-separable manner. The non-polarizing part () has a thickness (W) greater than a thickness (W) of the base part (). The base part () and the non-polarizing part () form a light transmitting member () that is a single solid member. The light transmitting member () is made of a colored resin.

Eyeglass lens, eyeglasses, and eyeglass lens manufacturing method

This invention provides a clip-on memberincludes a lens mounting rodto which clip-on lenses are mounted, and a pair of upper clipping armsand another pair of lower clipping armsmade of elastic members for attachment to the eyeglass frame. The upper clipping armsinclude an upper hooking partand another upper hooking partwith which the upper clipping armsare fitted and mounted to the brow part of the spectacle frame from above. The lower clipping armincludes an arm part, an arm part, and a pinching part. The arm partsandhave left engagement part Sa and right engagement part Sb respectively held by the holding partsand, and placed at the nasal area of the spectacle frame between its right and left lenses. The lower left and right hooking partsand, as an extension of the clipping armsand, exercise theft elastic force towards the opposite sides, thus moving away from each other.

Clip-on type eyeglasses

This invention is to provide an inexpensive lens can be worn without attention to the existence of the addition power segment of conventional polarizing lens, it and a bench lens are formed integrally on the rear surface of a polarizing member. The present inventors constituent a polarizing memberby sandwiching poly vinyl alcoholas a polarizing film with poly carbonatewhose both surfaces are stretched, and mold resin' on the rear side of the polarizing member, and arrange an addition power segmentintegrally on the rear surface, make the molded resin poly carbonate sandwiches the polarizing film. The top and the bottom of this member are cut as FIGs. to form lens at low costs, and the adhesion among respective resins is increased, and to secure the impact resistance and it is possible to create a lens without detachment because of same resin.

Method for manufacturing bifocal lens

The present invention relates to a sunglass attachable to a pair of glasses at a later stage, which sunglass is reliably attached to the glasses and in which a sunglass plate is stably held at a flipped position, and also relates to an attachment fitting thereof. The attachment fitting includes a shaft strip, a base, a base contacting strip, an elastic body, and an elastic receiving strip. The base is rotatable with respect to the shaft strip, and the base contacting strip and the elastic receiving strip are fixed so as not to rotate with respect to the shaft strip. With the elastic force of the elastic body, the base contacting strip is pressed towards the base and the base contacting strip and the base are engaged, thus allowing the sunglass plate attached to ends of the shaft strip to be freely raised upwards and lowered downwards and to be freely stopped in stages.
