The variable angle-mirror, a new tool for the study of ocular dominance and eye fixation

A simple tool for studying optical dominance consisting of two plane mirrors moveably fixed to one another was developed. The patient looks straight ahead at the reflection of his own face and observes which eye is covered by the joint between the two mirror halves. By changing the angle a further checkup on eye dominance can be obtained. The method is simple and gives us a quick idea of the eye dominance.
