PURPOSE:To improve the work efficiency, and to improve the measuring accuracy by constituting one set of measuring jig so that an ocular lens can be fixed in various directions, and the lens can be observed from every angle, at the time of executing various tests for checking a mechanical characteristic of the ocular lens. CONSTITUTION:An interval of a pair of ocular lens inserting and holding plates 10, 10 is set arbitrarily by a moving device 14 so that the diameter of a circular lens holder part 60 for holding an intraocular lens can be adjusted. Also, the ocular lens inserting and holding plates 10, 10 are rotated around a first horizontal axis A which passes through the center of the intraocular lens by a first rotating means containing a rotary plate 34, fixed in an arbitrary position, and also, rotated around a second horizontal axis B which passes through the center of the ocular lens, and also, crosses with a first horizontal axis A at a right angle by a second rotating means containing a rotary plate 48 and fixed in an arbitrary position, and in a state that the center of the ocular lens remains fixed, its direction can be changed arbitrarily.
