Kahlu answers: Thanks for your question. I love it. Minus lenses are heavily promoted because on the surface they give the illusion of 'correcting' a problem dictated by 'modern' eye medicine's insistence that nearsightedness is a structural eye problem. This narrow way of viewing lenses seems innocous.

Minus lenses are a drug. (You need a lens prescription to get them) Doctors know this. It is good for you to remember this. A minus lens is a sympathetic stimulant. Some of the actions resulting from this nervous system activation includes pupil dilation, increased heart rate, reduced intestinal motility, liver activation, and increased adrenal medulla secretion of norepinephrine and epinephrine.

Increase in pupil size is known to reduce visual acuity over time. Most eye doctors prescribe a minus lens for nearsightedness so the person's eyesight is returned to 20/20. However, research shows that in at least 80 percent of the time, the full minus lens prescription induces a disruption of the binocular integration. Superficially this may not seem like a monumental side effect.

On the other-hand, what happens to the human being who is over stimulated with a too strong minus lens prescription? If they are less binocular, they internally feel less integrated in their life. They see less into the depth of what it means to be human. They behave more mental and rely on thinking and looking through understanding. They over use logic to solve life problems, and feel less.

Is it possible that many of the problems you see in people and on our Earth these days come from this 'drugged' way of perceiving. When minus lenses are measured for maximum integration, the power is usually less. The lower minus lens prescription results in the person seeing and feeling more. Apparently, this happens because there is less foveal focus and more retinal stimulation.

In the long run, this 'lower minus lens' approach becomes useful for those who wish to undertake an active vision improvement approach. Kahlu.
