Document Type and Number:
Japanese Patent JP7132078
Kind Code:
B2
Abstract:
To address such a problem that, with multifunctionalization of vision correction glasses, the number of test lenses to be installed on a test lens frame is liable to increase, and to provide a function capable of retaining a cornea vertex distance from a cornea vertex of a user to a test lens rear face, to an appropriate value.SOLUTION: An optometry frame includes a pair of test lens frames, a pair of temples, and nose pad parts from which a pair of pads are vertically provided. The nose pad parts are comprised of a block-shaped base part and body parts swingably connected to the base part in a hinged state. Each rising piece rising upward in front of a pivot shaft is formed, and a through-hole penetrating the front and back of the rising piece is provided at an intermediate portion thereof. A female screw is formed at an internal periphery of the through-hole. A shaft that includes a male screw to be threadedly engaged with the female screw, at an outer periphery thereof is inserted into the through-hole, and a terminal end of the shaft is rotatably journaled to the base part, so that, by rotating the shaft, the body part of each nose pad part can be displaced in the longitudinal direction.SELECTED DRAWING: Figure 3
