Abstract
My invention is an automated self-testing method utilizing binary choice, which is applicable to monocular and binocular eye tests and can be administered on computer, cellular phones, and other electronic devices. Binary choice of match or no match, yes or no, present or absence provides simple means of automated testing by stepwise progression through staircase algorisms. Necessary devices have been introduced in order to fully utilize the power of binary choice self testing, such as, (1) printed display overlays for testing fine visual acuity at near, (2) bright illuminator of printed overlays to allow automated potential vision testing, (3) the use of complementary color lenses and color test isopters for binocular perimetry. All the programs are linked together in a multifunction electronic program tailored for Internet applications
