Abstract: A hybrid lens for eyeglasses comprising a frame-mountable, optically transparent lens having an anterior surface and a posterior surface. The anterior surface has a surface area. A polarizing segment is affixed to the optically transparent lens such that the polarizing segment is coextensive with a midportion of the anterior surface area of the optically transparent lens wherein the midportion of the surface area of the optically transparent lens that is coextensive with the polarizing segment is less than the anterior surface area of the lens. In a preferred embodiment, the optically transparent lens has a top edge, a bottom edge and a geometric center. An imaginary horizontal centerline drawn through the geometric center divides the optically transparent lens into an upper portion and a lower portion. The polarizer segment comprising the hybrid lens is a relatively narrow, elongate horizontal strip disposed within the lower portion of the optically transparent lens adjacent to, or overlying the centerline.

Abstract: A device for self-determining a person's pupillary separation in an OTC setting. In a first embodiment, the device includes a plurality of interconnected masks, each mask having two holes therein, the distance between the center of the holes being indicated on the mask. The separation of the holes is different for each mask. The user places the respective masks before the eyes and looks through the holes. The optimal interpupillary distance is determined by the clearest vision experienced by the user when looking through the holes. In a second embodiment, a single mask is presented wherein the distance between two holes is varied continuously until a single hole is perceived by the user, and the interpupillary distance read from a ruled scale on the device.

In a first embodiment, the device includes a plurality of interconnected masks, each mask having two holes therein and the distance between the center of the holes being indicated on the mask. The separation of the holes is different for each mask. When the user places the respective masks before the eyes and looks through the holes, if the separation between holes is unequal to the user's interpupillary distance, a fuzzy or double hole will be perceived by the user. When the hole spacing is equal to the interpupillary distance, a single, well-defined hole is perceived by the user. In a second embodiment, a single mask is presented wherein the distance between two holes is varied continuously until a single hole is perceived by the user, and the interpupillary distance read from a ruled scale on the device.

Abstract: A polyvinyl display device for bifocal computer/reading spectacles. The display device enables a person to identify a pair of spectacles having the correct optical center to match the wearer's pupillary separation. The present invention includes, in combination, a pair of spectacles having two near focal powers and a new type of display mechanism that allows the purchaser to choose not only the correct power needed, but also the correct pair of glasses to match the user's pupillary distance (PD). Optical centers of finished reading glasses are marked, then a display device including an opaque polyvinyl static cling film having two, preferably round, holes therein is placed onto the glasses such that the holes in the film overlie the optical centers. When the user dons the glasses, if a solid round area is viewed, the spectacles have the correct size for the user's PD. If a figure eight or two holes is viewed, the PD is too wide. If the user views the outside edges, the PD is too narrow.
