Abstract

The invention provides an eyeball protrusion measuring instrument and measuring method. The eyeball protrusion measuring instrument comprises a base, a support, a baffle, a measuring assembly, a fixing assembly and a control assembly, wherein the fixing assembly is used for fixing the head of a testee, and the measuring assembly comprises a track, a distance measuring sensor, a light emitter and a first driving part; and the eyeball protrusion measuring method uses the eyeball protrusion measuring instrument to measure the eyeball protrusion of the testee. According to the eyeball protrusion measuring instrument and measuring method, the light emitter emits visible light to assist in calibrating the position of the bitamporal orbital marginal bone of a testee, and the control assembly controls the first driving part to drive the distance measuring sensor to move on the track, so that eyeballs of the testee are automatically scanned, the cornea vertex is recognized, and errors caused by manual operation are avoided; and besides, the measuring environment of the left eye and the right eye is isolated through the baffle, so that the situation that the measuring result is wrong due to inconsistent eyeball protrusion is avoided, and the measuring precision of the eyeball protrusion is effectively improved.

Description

Technical field[0001]This application belongs to the field of eyeball protruding measurement technology, and more specifically, it is involved in an eye-based protrusion measuring instrument and a measurement method.Background technique[0002]Eyeball project refers to a vertical distance from the eyeball due to the increase in contents in the eyelid, while the eyeball protrusion is a vertical distance of the temporal bone bone to the corneal vertex.[0003]At present, the mainstream method for measuring the eyeball projections is the HERTEL eyeball protrusion measurement method, and the Hertel eyeball protruding meter is an optical glass prism that passes the equal waist angle triangle, and the cornea vertex and the scale ruler are simultaneously projected to the front of the prism. It can be observed in front of the human eye to obtain the height of the outer frame. However, there is a lot of problems in the Hertel eyeball protrusion:[0004]1. The point of the temporal bone bone is rep...
