Equipment and method for testing comprehensive vision functions

Abstract

The invention discloses equipment and a method for testing comprehensive vision functions. The equipment for testing the comprehensive vision functions comprises a first display and a vision function tester. The vision function tester is connected with the first display; the display can display video data under the control of the vision function tester, and the video data are used for testing at least one vision function by the aid of the vision function tester; the vision function tester is provided with a vision acuity testing module and a spatial contrast sensitivity testing module; the vision acuity testing module is used for testing the vision acuity; the spatial contrast sensitivity testing module is used for testing the spatial contrast sensitivity. According to the scheme, the equipment and the method have the advantages that the vision acuity and the spatial contrast sensitivity can be tested, accordingly, the comprehensive vision functions can be tested, the problem that only the vision acuity can be tested while the vision cannot be comprehensively assessed is solved, and the equipment and the method are favorable for finding defects of certain vision functions of tested objects and beneficial to follow-up treatment on the tested objects and have high practical value.

Description

technical field [0001] The present invention relates to visual function detection, in particular to a comprehensive visual function detection device and method. Background technique [0002] The visual system of the human body plays an important role. Among them, visual cognition mainly includes two processes. The first is that the object is refracted and imaged on the retina by the human eye, and the second is that the imaging information is transmitted to the brain through the optic nerve for processing. Visual function is an index to assess whether the visual system is normal. It covers everything from visual acuity to visual attention, from contrast sensitivity to motion processing. [0003] However, in clinical ophthalmology, there has been a lack of assessment of visual function. It is only a simple examination of the visual acuity of the patient, and this single index is used as the basis for the treatment of ophthalmic diseases; for example, there is no spatial cont...

[0003] However, in clinical ophthalmology, there has been a lack of assessment of visual function. It is only a simple examination of the visual acuity of the patient, and this single index is used as the basis for the treatment of ophthalmic diseases; for example, there is no spatial contrast sensitivity (Contrast Sensitivity Function, CSF) test

Visual acuity is visual acuity, also known as visual resolution; for the vast majority of patients, it is difficult to find out which visual functions the patient has defects in, so that the treatment effect cannot achieve the ideal visual quality of the patient

For example, after many amblyopic children are treated in the hospital, even if their eyesight returns to normal levels, their binocular vision function is still defective, and it is difficult to obtain normal stereoscopic images, which causes a lot of trouble to their daily life
