Question: 2 vision improvement programs talk about your current prescription overcompensating while your vision is improving what does this mean the 2 programs say that you don't need a weaker prescription while improving your vision what's your viewpoint on this.

In 1982, I conducted a study on nearsighted individuals. While wearing their normally 20/20 (100 percent) compensating lens prescriptions, I measured the levels of visual stress that these lenses introduced. In over 80 percent of the cases, the measurements implicated a breakdown in two-eyed vision when they saw 100 percent. Why? Stress upon the visual system can be measured as a lack of binocular vision performance.

I then lowered the lens prescription for each person until the visual stress was eliminated or maximally reduced. On the average this occurred with about one diopter less than the normal compensating lens prescription. The level of eyesight for most of the participants was still good enough for driving through these lenses.

Now here is the next profound findings. When the subjects wore these lenses, and conducted a prescribed vision therapy program, their eyesight began to improve through the weaker glasses. If they ate something that was not good for them, had negative thoughts or became mentally tense in their narrow beliefs, the eyesight got worse. In other words, the weaker glasses are precisely designed to act as biofeedback device that serves as a measure of improvements or slipping into stress again.

So, when I work with clients, I use weaker lens prescriptions in this way. In addition, later I can modify cylindrical lens prescriptions as well. - Roberto Kaplan
