发明名称 Vision testing system
摘要 A subjective vision testing system is used for visual function tests for examinees. The subjective vision testing system is provided with an optometric apparatus which selectively sets optical elements in front of both eyes of an examinee, an optotype presenting apparatus for displaying optotypes to the examinee, and a controller. The optotype presenting apparatus, based on a command signal for implementation of a binocular balance test, displays optotypes used for binocular balance tests. The optometric apparatus, based on a command signal for implementation of a binocular balance test, sets a first prism in front of the examinee's right eye and a second prism in front of the examinee's left eye. The second prism has a base direction vertically opposite to the first prism and the same prism power as the first prism.
