Method for making ophthalmic measurements

DETAILED DESCRIPTION We claim: 1.
The method of making ophthalmic measurements for glazing spectacles frames comprising the steps of: adjusting a preselected spectacles fra,e having a pair of lens rims for proper fitting thereof to a patient's face before his two eyes; detachably connecting a measuring means carrying an aligning reticle to said frame with said reticle disposed within an area circumscribed by one lens rim of the frame; placing said frame in proper wearing position upon said patient's face with said measuring means thereconnected and said one lens rim located forwardly of one of said patient's two eyes; aligning in a single operation a single preselected point on said reticle with a preselected point on said one of said patient's eyes; and in a single step measuring from said single preselected point on said aligned reticle the distances directly therefrom to both an extreme lateral and the extreme inferior points on said lens rim of said frames, said measurements being applicable to the finishing of an opthalmic lens for glazing in said rim.
2.
The method according to claim 1 wherein said measuring means includes a second aligning reticle disposed within an area circumscribed by the second lens rim of said frame and said steps of aligning and measuring are repeated in conjunction with the patient's second eye.

BACKGROUND OF THE INVENTION 1.
Field of the Invention This invention relates to improvements in measuring apparatus and method for use in fitting ophthalmic lenses in spectacle frames and has particular reference to applying the ophthalmic measurements directly to frames selected by the patient.
2.
Description of the Prior Art The fitting of lenses to various types of frames selected by patients is ordinarily a tedious, time-consuming and relatively difficult undertaking requiring special skills.
It having been generally recognized that the several measurements necessary for optimum ophthalmic glazing are critical, various aids including special scales Pupilometers and frame or lens measuring fixtures have been recommended for obtaining some measurements
