FIELD: medical engineering. SUBSTANCE: device has focusing optical element and test object. The focusing optical element is coupled with the test object placed in focal plane of the focusing optical element in normal vision function cases. Both test object and focusing optical element are movable relative to each other along the optical axis. EFFECT: high accuracy in determining eye refraction and accommodation; simplified device design; enhanced effectiveness in training eye muscles. 59 cl, 6 dwg
