People whose eyes are stressed often see fleeting images. These are similar to the images on a television screen after a station has signed off: patterns and colors that move about but often appear gray and diffused. The eyes even mirror mental restlessness. You experience this as swishing images and incomplete darkness when you close your eyes.
Therefore, this exercise is a good way to measure your rental state, as well as your eyesight. When you shield tour eyes, the transition from a shimmering, gray state to leep blackness indicates the change from actively seeing o a totally relaxed, restful state. Read the rest of this entry »
It is also obvious that the method must have prevented other errors of refraction, a problem which previously had not even been seriously considered, because hypermetropia is supposed to be congenital and until not long ago astigmatism was also supposed to be congenital in the great majority of cases. Anyone who knows how to use a retinoscope, however, can demonstrate in a few minutes that both of these conditions are acquired; for no matter how astigmatic or hypermetropic an eye may be, its vision always becomes normal when it looks at a blank surface without trying to see.

At the request of the superintendent of schools in Grand Forks at that time, the system was introduced into all the schools of the city and was used continuously for eight years. During this time it reduced myopia among the children, which I found at first to be about six per cent, to less than one per cent.
A few years later the same system was introduced into some of the schools of New York City, with an attendance of about ten thousand children. Many of the teachers, however, neglected to use the cards, being unable to believe that such a simple method, and one so entirely at variance with previous teaching on the subject, could accomplish the desired results.

To repeat a very important principle: you 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 absolutely normal under other circumstances. The same thing happens when adults look at unfamiliar distant objects. When the eye regards a familiar object, however, the effect is quite different. Not only can it be regarded without strain, but the strain of looking at unfamiliar objects later is lessened. Read the rest of this entry »
