Interior the convex lens sheet group set gradually from peep hole to visual angle hole, template and the baffle plate that can be opened and closed；Set on the template
There are light source and image capture device, offered on the template using template geometric center as some fixed coordinates of origin
Through hole.
Further, the convex lens sheet group and the distance between the template are adjustable, for adjusting measurement distance.
Further, the peep hole outer rim is provided with pad ring, meets ergonomics.
Further, the power supply unit being connected with the test section is additionally provided with the housing, for ensureing test section just
Often work.
Further, connected between the test section and the data handling system by data transmission system, for examining
Data are transmitted to data handling system in real time caused by survey portion.
Further, the measurement apparatus also includes speech prompting system, and the speech prompting system can be by described
Data handling system management manipulates, and person under test can independently complete to test according to the operation instruction of speech prompting system, more intelligence
Energy.
The beneficial effects of the utility model are：The utility model proposes a kind of cornea optical reflection method slant visibility measure dress
Put, the slant visibility of person under test is measured using the test section being arranged in housing, due to the presence of observation panel so that detection
The relative position of the image-capturing apparatus in portion and the eyeball position of person under test is constant all the time, and inspection result will not be by measurement ring
Border, person under test the extraneous factor such as behavior state influence, ensure the accurate of testing result；And convex lens group and template
Different positions can be adjusted, adjusts measurement distance, is easy to draw multi-group data, makes final testing result more objective
It is accurate to see.

Embodiment
To describe technology contents, construction feature, institute's reached purpose and effect of the utility model in detail, reality is hereby enumerated below
Apply example and coordinate accompanying drawing to be explained in detail.
Embodiment 1
Refer to shown in Fig. 1-2, the utility model provides a kind of cornea optical reflection method slant visibility measurement apparatus, including body and
Data handling system, body include housing 1 and test section, offer peep hole 2 on two relative sides on housing 1 and regard
Corner apertures 6, test section include the interior convex lens sheet group 4 set gradually from peep hole 2 to visual angle hole 6 of housing, template 5 and can opened
