Abstract

The invention relates to a test table, in particular to an ophthalmic vision test table. Therefore, the technical problem of the present invention is to provide an ophthalmic vision test table that enables a patient to see the symbol clearly and has a good test effect. The technical embodiment of the invention is as follows: an ophthalmic visual acuity test table comprises a bottom bracket, a U-shaped bracket, a first bearing, a first shaft, a first reel, a second bearing, a second shaft, a second reel, a first rocker arm, a visual acuity chart and the like. The top of the bottom bracket is connected with a U-shaped bracket, the left and right sides of the U-shaped bracket are provided with sliding grooves, the left side sliding groove left wall and the right side sliding groove right wallare uniformly provided with a plurality of grooves, and the lower parts of the left and right sides of the U-shaped bracket are provided with first bearings. A medical staff grasp that first rocker arm and rotate or reverse the second shaft rod, and the second shaft rod rotates or reverse to drive the second reel to rotate or reverse, thereby driving the visual acuity chart to rotate, so that symbols seen by the patient from the t hole are different in size, and the eyesight of the patient is tested.

Description

technical field [0001] The invention relates to a test table, in particular to an ophthalmology vision test table.
