Embodiment

[0115] The usual optometry is divided into three main processes: 1. In the initial stage, the optometrist conducts general medical history inquiry, routine eye examination, general general condition inquiry of the examinee, and then conducts corneal curvature examination, followed by retinoscopy optometry, computer Optometry or other objective optometry, and finally test the degree of glasses of the subject. 2 Accurate stage, check the prediction data obtained in the initial stage, and then carry out detailed subjective refraction through the comprehensive refractometer. 3. In the final stage, the final optometry prescription of the examinee is obtained through the try-in technology of the trial frame. Among them, the detection process of subjective optometry is roughly as follows: the first MPMVA (maximum plus to maximum visual acuity), that is, to find the initial effective spherical lens power, and then pass the precise verification of JCC (Jackson cross-cylinder, cross cyl...

Abstract

The invention discloses self-help subjective refraction intelligent wearing equipment and a lens degree calculation method. The equipment comprises a lens module, a calculation module and a control module. The lens module includes more than one set of double-sided zoom lenses, each group of two-sided zoom lens comprises two double-sided zoom lenses, and each double-sided zoom lens comprises two symmetrical and mirror-designed zoom curved surfaces; the control module drives the two groups of double-sided zoom lenses to move in a staggered way through a motor so as to realize zooming.

Description

technical field [0001] The invention belongs to the field of medical optometry technology and optometry equipment, and in particular relates to a self-service subjective optometry smart wearable device and a lens power calculation method. Background technique [0002] There are two types of medical optometry: objective optometry and subjective optometry. Traditional optometry is a dynamic, multi-program clinical diagnosis process. From an optical point of view, optometry is to allow distant parallel light rays to pass through the corrective lens in front of the subject's eye and land on the macula of the retina to form an object-image conjugate relationship. The standard subjective optometry process is complicated, time-consuming, highly cooperative, and requires high professional skills, making it impossible for the general population to obtain eye diopters quickly and easily. Objective retinoscopy has high technical requirements for the examiners themselves, and cannot b...
