An equipment for measuring heterophoria and convergence comprising a diagnosing instrument (10) provided with a pair of inspection holes (20) corresponding to the pupil distance, and measuring plates (60, 70) disposed in front of the inspection instrument. The diagnosing instrument comprises a hollow housing (12) disposed on the front side of the inspection holes, a dividing plate (50) for dividing the internal region of the housing in an oblique direction, and a shield means (40) which can open/close one inspection hole selectively. The inspection holes open to the respective sides of the dividing plate and the look-through region from each inspection hole is divided by the dividing plate. The diagnosing instrument forms a single eye shielding state and each look-through state for measuring vertical heterophoria, inner/outer heterophoria and convergence by opening/closing operation of the shielding means. Powers of heterophoria and convergence are measured by subjective test where a person to be examined looks at a lateral line or a longitudinal line of the measuring plate under a state of view divided centrally by the dividing plate.
