Abstract

The present invention relates to a dynamic vision detection system and method. The system includes: an eye movement instrument control unit, an information collection unit, an optotype control unit, a data processing unit, a display unit and an output unit; an eye movement instrument control unit for sending The control instruction is sent to the information collection unit to control the data collection of the eye tracker; the information collection unit is used to collect the visual mark opening determination data input by the testee and the pupil tracking data of the testee; the visual mark control unit is used to output The visual target information is sent to the display unit; the display unit is used to display the visual target information according to the preset visual target parameters; the data processing unit is used to judge the data according to the visual target opening, the pupil tracking data of the tested person and the output visual target information , to determine the test result of the testee; the output unit is used to output the test result of the testee. Through the technical solution, the pupils of the testee are tracked during the vision test, thereby improving the accuracy of the dynamic vision test.

Description

technical field [0001] The present disclosure relates to the technical field of vision detection, in particular to a dynamic vision detection system and method. Background technique [0002] Dynamic vision refers to the observer's ability to distinguish the details of objects that are moving relative to them. At present, the examination of visual function and visual acuity in clinical practice is mainly limited to static visual function and static visual acuity. However, with the continuous advancement of ophthalmic medical technology and the continuous improvement of people's medical expectations, the needs of a large number of ophthalmic patients after treatment are not limited to sight recovery, but to improve their quality of life through diagnosis and treatment. Most of the visual objects around us are in motion, and good dynamic vision is very important for quality of life, sports and driving safety. At this time, the assessment of static vision alone is far from eno...
