A visual acuity testing device that switches and displays visual acuity within a frame, comprising: an optotype set switching means for switching to an optotype set having an optotype to be presented to a test subject; an optotype specifying means for specifying an optotype of a value; an acuity value extracting means for extracting an acuity value of an optotype to be read by the subject from signals from the optotype set switching means and the optotype specifying means; It consists of a memory switch that stores the final visual acuity value that the examiner was able to read as the test subject's visual acuity value, and an input means that inputs the stored visual acuity value of the test subject into a subjective ophthalmoscope or a computer. A visual acuity testing device characterized by:
