Ophthalmic examination macyscope capable of preventing side lens peeping

Abstract

The invention discloses ophthalmic examination macyscope capable of preventing side lens peeping. The macyscope includes a frame, a red lens, a green lens, temples, blocking pieces and soft silicone layers; the green lens is arranged on the left side of the frame, and the red lens is arranged on the right side of the frame; the inner side of the frame is provided with the blocking pieces; a raised bump is arranged at the upper part in the middle of the blocking pieces; and the soft silicone layers are arranged on the inner sides of the blocking pieces. Through the arrangement of the soft silicone, the blocking pieces and the bump, the inner circumferences of the soft silicone fit with the surrounding of the eyes of a person; and as the bump is arranged at the upper parts of the blocking pieces inside the red and green lenses, when the macyscope is in use, the surrounding of the eyes of the patient can be blocked and can only see the front lenses, thereby blocking the light that the patient obliquely observes from above, and the accuracy of observation and examination can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of ophthalmic examination, and in particular relates to red-green eyeglasses for ophthalmic examination with anti-peeping side pieces. Background technique [0002] When checking whether the patient has monocular suppression, diplopia, and binocular fusion, it is necessary to use the worth4-point optotype, hand-held worth4 lighting, red-green glasses or red-green filters. Worth4 lighting inspection mainly uses the method of red-green separation to check binocular vision. It uses the principle of red-green complementarity to check the patient's binocular vision under the condition of split vision. Using the Worht 4-point optotype or four circular lights placed on a black or gray background, the four lights consist of one red, one white, and two green lights, illuminated from the inside, and the patient wears red-green glasses, The green lens is worn on the left eye, and the red lens is worn on the right eye...

AI Technical Summary

Problems solved by technology

However, the shape of the red-green glasses for traditional inspection is the same as that of ordinary glasses, which makes it inevitable that some patients will look at the light from the oblique top of the glasses or other edges of the lenses during the inspection, which will affect the accuracy of the final inspection results.
