William Horatio Bates, Better Eyesight Magazine — August 1919
“ THE PREVENTION AND CURE OF MYOPIA AND OTHER ERRORS OF REFRACTION A Method That SucceededYou cannot see anything with perfect sight unless you have seen it before. When the eye looks at an unfamiliar object it always strains more or less to see that object, and an error of refraction is always produced. When children look at unfamiliar writing, or figures, on the blackboard, distant maps, diagrams, or pictures, the retinoscope always shows that they are myopic, though their vision may be under other circumstances absolutely normal. ”
