Through the years Dr. Sirota has developed a series of tests in addition to the traditional means of testing the eyes. They involve balance, flexibility, size constancy and spacial orientation. The doctor carefully watches his patients' movements, breathing, muscular tension and the subtle changes caused by different lenses. One test that Sirota does is to have someone stand solidly on their feet. With his open hand he gives them a gentle push forward on their lower back.
Some people are very rigid and tight.
Others, who have little resilience, almost fall on their faces. Some move up on their toes and return not exactly an appropriate flexibility. All these responses change with a change in lenses. The person doesn't see distortion, instead, his or her behavior makes the adjustment by becoming distorted warping the body or mind. Dr. Sirota asked one patient to wear an old pair of her glasses for a while before he would prescribe new ones.
