1940 Press Photo Edsel Ford eye examination

Caption: HOW'S HIS EYE DOMINANCE? In this test Edsel Ford maniplates a pair of screens by turning a knob with hisleft hand. This shows whether he uses both eyes equally, or has a tendency to favor one of them. Eye dominance is a factor in seeing straight on the road. Edsel Ford did better-than-average in this test. The examiner shown at the left is Prof. R.A.Moyer, engineering teacher at Iowa State College, and Dr. laur's assistant in the League tests.
