Claims

[Scope of utility model registration request]

A dark box, an optical system for displaying a test target in the dark box, a binocular peephole and a forehead rest for viewing the test target from the front of the dark box, and a system in which a subject responds to the recognition of the test target. A device comprising a response switch that is operated by a user, a circuit that determines the response signal, proceeds with the test, and outputs test data at the same time as the test is completed, and a display that displays this output. An automatic visual function testing device comprising: a forehead detector that detects when the subject's forehead comes into contact with the object and outputs a signal; the detection signal is used to proceed with the test and output test data. .
