    Abstract: A portable visual acuity examination device comprises a mounting unit that can be mounted in front of eyes either using or not using eyeglasses, a visual target displaying unit that uses an organic EL display panel, a display controlling unit that changes the visual target displayed on the displaying unit, an inputting unit for visual target viewing results, and a transmitting unit for measurement results. The portable visual acuity examination device comprises an optical system that can change the distance at which the visual target virtual image is visible. The portable visual acuity examination device detects whether eyeglasses are used and matches an uncorrected vision acuity examination and a corrected vision acuity examination. The portable visual acuity examination device switches between a C-type visual target and an E-type visual target. With data display, both the right and left display units are enabled.
