In order to investigate the nature of suppression, I attempted to produce apparatus of four polaroid filter test, using four polaroid filters.

These tests were carried out in some cases of amblyopia and squint patients, and the results of the tests were more acurately than Worth four dots test which had been used generally. The four polaroid test was consisted two sets of two dots, which each other placed at right angle, attached polaroid filter. Indicater of the test was variation of four dots light induced by electric voltage control. Perception of patients to the four dots light value could be exsibited mathematically.
