An ocular angle deviation measuring indication tool and a heterophoria measuring method using the same are provided to enable an oculist to reliably calibrate a heterophoria by measuring both vertical and horizontal heterophorias at the same time. Guide lines(21a,21b) are marked to be apart from each other in a horizontal heterophoria measuring unit(20). Horizontal heterophoria grids(22a,22b) are marked between the guide lines. A horizontal ocular angle deviation indicator(23) is marked downward at the center of a lower guide line. A vertical heterophoria measuring unit(30) is displayed under the horizontal heterophoria measuring unit. Horizontal measuring lines(31) are marked to measure a vertical heterophoria and a vertical ocular angle deviation. A vertical measuring line(32) is marked downward in the middle of the horizontal measuring line. Numbers are displayed on the vertical measuring line with a spacing of one prism diopter, so that vertical measuring grids(33) are formed. |
