He was delighted to be making these changes and improving his attention as well. In other words, there seemed to be some factor, some feeling or sensation that helped this man choose a lens that enabled him to see better. From this situation, the doctor clarified his own intention of using his craft not only to compensate for poor vision but to encourage better vision. He realized that good vision included factors more complex than being capable of seeing a small letter on a chart out of context with everthing around it. Good sight is not synonymous with good vision, says Sirota.
Sight is the ability of the eye to see things.
Vision is the ability to make sense out of what one sees. 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.
