Abstract

The invention relates to an eye vision measuring apparatus. The eye vision measuring apparatus comprises a base and a storage slot; internal through grooves are arranged inside both the left end and the right end of the bottom of the base; a transmission rotor is arranged at the middle of a bottom end of the base; an inner groove is arranged outside the transmission rotor; a top end of the inner groove is connected with a limit plate; a top end at the middle of the base is connected with a central column strip; a slot is arranged inside the central column strip; a slot post is arranged at an inner end of the slot; a central storage piece is arranged at the middle of the slot post; and a feeding port is connected with the outer side of a top end of the central storage piece. The eye visionmeasuring apparatus has the following beneficial effects: by arranging the storage slot, a connecting piece and a spring column, the eye vision measuring apparatus is capable of connecting and placingthe connecting piece through the storage slot with large caliber; cooperated use of the connecting piece with side connecting bolts is facilitated by curved structures at both the left end and the right end of the connecting piece; and the connecting piece is pushed downward under elastic force of the spring column, so that, descending of the limit plate is facilitated so as to carry out brake operation.

Description

technical field [0001] The invention relates to the technical field of vision measurement, in particular to an eye vision measurement device. Background technique [0002] Vision refers to the ability of the retina to distinguish images. The quality of vision is judged by the ability of the retina to distinguish images. However, when the refractive media of the eye (such as cornea, lens, vitreous body, etc.) , farsightedness, astigmatism, etc.), even if the retinal function is good, the visual acuity will still decline, and the refractive medium of the eye is cloudy, which can be treated with surgery, while the refractive error needs to be corrected with lenses. [0003] A vision detection device disclosed in the Chinese Invention Patent Application Publication Specification CN 106821298 A, although the vision detection device can realize the adjustment of the same group of visual targets through a driving source, which can improve the adjustment efficiency and reduce the ma...
