Problems solved by technology

[0013]However, only the optometrist knows the details of the refraction through a hand-held retinoscope, and no third person can see the specific refraction process
Even if someone has proposed to take a retinoscopy image through a camera and display it on a monitor for teaching, there are still problems in the prior art that the camera cannot be quickly, stably, and accurately positioned to the eye to be inspected, so that the retinoscopy image cannot be taken quickly, lose practical value
Moreover, no variable telephoto lens is used, and retinoscopy images cannot be clearly captured

Abstract

The invention provides a digital retinoscopy optometry system. The digital retinoscopy optometry system comprises a workbench, a lower jaw bracket, a retinoscopy support, a retinoscope, a camera and a monitor; a connecting mechanism is arranged between the retinoscope and the camera; the connecting mechanism comprises a fixed plate, an axial rotating plate and a radial rotating plate which are coaxial and are provided with a center hole and accordingly retinoscopy images can be shot rapidly, stably and accurately; the camera with a long variable telephoto lens is used and accordingly clear images can be shot and displayed on the monitor conveniently. According to the digital retinoscopy optometry system, the retinoscopy optometry images can be displayed on the monitor; above all, the clear retinoscopy images can be shot in the retinoscopy optometry process rapidly, stably and accurately; accordingly the effects of intuitive optometry and intuitive teaching demonstration can be achieved.

Description

technical field [0001] The invention relates to a retinoscopy optometry system, in particular to a retinoscopy optometry system for displaying retinoscopy images through a monitor. Background technique [0002] Optometry is divided into subjective optometry and objective optometry. Subjective optometry requires the cooperation of the optometrist and the customer to complete the question and answer. Objective optometry can know the degree of the customer without the customer's answer. There are two kinds of insert optometry and comprehensive optometry. [0003] Traditionally, there are two types of objective optometry: computer optometry and manual retinoscopy. [0004] Computerized optometry is very easy to operate, and the results will be available immediately after focusing the optometry instrument on the eye. However, the operation of manual retinoscopy is relatively more complicated. The use of hand-held retinoscopy is highly random, and no one can know the process of...
