Is the Power Vision System based on any scientific elements?

FAQ n. 29. Power Vision System - Is the Power Vision System based on any scientific elements? How did you figure it out? Please, let me know how and where could I get it. . . . I did some exercises with a therapist for two years, and I had some small improvements (from –5 to –2.5 D), but then I gave up practicing because I was fed up, and probably my sight got worse. I work at computer a lot and my job requires a lot of near-work.

The Power Vision System is based on physiological reactions like SAID (Specific Adaptation to the Imposed Demand) or retinal defocus, which have important and proven effects on the human body. The SAID Principle concerns gradual bodily adaptation to specifically induced stimuli, which leads to functional and structural changes in the treated organ—in this case, the eyes and the visual system.

The principle of retinal defocus concerns focusing-system compensation or adaptation to the induced stimulus: in the case of myopia a person is subjected to myopic defocus (becoming more myopic, lessening dioptric power of his lenses, or in case of middle/low myopia wearing positive training lenses). Such a phenomenon is called “fogging” and represents a “trigger”—the stimulus for retinal compensation. The training is aimed at using retinal defocus/fogging masterfully and specifically for each and every case of myopia/hyperopia.

The Power Vision System could also be considered a scientific method, since it’s based on physiological laws that are ascertained by traditional science. In addition, the effects of retinal defocus have been ascertained in studies on animals and especially in primates/monkeys.

If by scientific you are asking whether the Power Vision System was tested and the results were published in the journals on optometry, I can inform you that such tests haven’t been done yet. They are likely to be tested in humans soon.

A new scientific and experimental thesis is never born together with a series of studies and experiments proving it; otherwise it wouldn’t be new or experimental. This process of scientific understanding, and the results of scientific experiments, are described in Thomas Kuhn’s book, The Structure of Scientific Revolutions (1996;3rd ed.).

The Power Vision System has been written to explain and detail a system of treatment concerning both the physiological laws that it is based on as well as psychological phenomena beyond the visual system, such as bioenergetics. The system has worked in my case, but it’s up to each of us to check out its validity—taking upon ourselves the responsibility while being supervised by an oculist or an optometrist.

If you want to see whether this system works, you need to do the following: try to feel the effects of myopic retinal defocus without wearing contact lenses or glasses for half a day (you must be at a safe place, where you aren’t supposed to wear full correction for your personal or others’ safety). You are likely to notice or, at least, to have impressions of, better visual acuity at the end of the experiment: such improvement is a direct consequence of the visual system adapting to retinal defocus.

The Power Vision System acts directly and gradually, stimulating the visual system, getting used to and aiming at gradual regressing of functional visual error. Since the error is functional, the problem should be resolved by acting over working ability: this is the basis of visual reeducation.

You say you’re working at a computer, being obliged to view near, and you’ve also noticed that your sight has gotten worse after some positive results you achieved while working with your(very good) therapist. This phenomenon is due to the fact that you are constantly subjected to overaccommodative stress and constant visual axis’ converging (the latter needs the process of accommodation to act). If you want to keep all the positive results you have reached, you must allow your eyes to “space” over long distances. In doing so, the tonic accommodation will relax and the ocular axis will become parallel (eliminating the stimulus for converging).

As a preventive measure, you can also wear undercorrection (ora plus lens) when working at the computer. It is enough to wear undercorrection whenever you carry out near-distance activities or to lessen the accommodation through positive lenses. In the end, I would like to tell you that it works—really works! Certifications, diplomas, and scientific studies aren’t needed to ascertain something from our own experience. Work with the Power Vision System while being supervised by a physician, optometrist, or ophthalmologist.
