Trial frame for measuring dominant eyes

Abstract

The invention discloses a trial frame for measuring dominant eyes, which comprises a measuring lens (1), a connecting rod (2) and a main eye plate (4). An insert rack (5) is arranged on the front side of each of lens frames of the measuring lens (1), the connecting rod (2) is fixedly arranged on the outer side of the middle of a lens rack between the two lens frames of the measuring lens (1) and is perpendicularly connected with a plane of the mirror rack, the other end of the connecting rod (2) penetrates through a slide hole (8) at a vertical center line on the upper portion of the main eye plate (4) to be slidably connected with the main eye plate (4), and a detecting hole (9) which is located below the slide hole (8) is arranged on the main eye plate (4). The connecting rod which is marked with graduations and is slidably connected with the main eye plate is disposed on the front side of the measuring lens, so that an examinee can independently determine the specific direction of a dominant eye, measurement of the dominant eye with different refractive error degrees at different distances is realized, and simultaneously, a measurement procedure and a measurement appliance are standardized. In addition, the trial frame has the advantages of convenience in operation, accurate measurement and wide application range, and is suitable for popularization and application.

Description

technical field [0001] The present invention relates to the field of ophthalmology and optometry instruments, in particular to the field of instruments for measuring human binocular vision function, in particular to an instrument for ophthalmology clinical examination and optometry to provide interpupillary distance and different photometric lens inserts for measuring advantages eyeglass frame. Background technique [0002] Clinically, the measurement of the dominant eye is very important, especially for refractive error correction with glasses, presbyopia and monovision (Monovision) fitting, strabismus amblyopia requires vision training after glasses, masking training, or strabismus surgery and The dominant eye should be tested whenever refractive surgery is indicated. There are many ways to detect the dominant eye, such as the card hole method, the thumb method, the convergence near-point method, the priority gaze method and the Worth 4-point method. The card hole metho...

Problems solved by technology

In addition, if the hole-in-the-hole method is used daily, in many cases, the examinee cannot correctly determine the position and placement distance of the dominant eye measuring device, which may affect the results, the implementation of the standard optometry process and the acquisition of accurate optometry results

Existing conventional trial frames generally have the function of determining luminosity and interpupillary distance, but do not have the function of measuring the dominant eye. As one of the procedures of optometry, the measurement of the dominant eye needs to be measured frequently to reduce the inspection time and optimize the inspection process.
