Help! My sight is getting worse and worse...How could I avoid harming my sight for the rest of my life?

FAQ n. 30. Power Vision System - Help! My sight is getting worse and worse. How could I avoid harming my sight for the rest of my life? I’ve been a myopic for some years (0.25—0.50 D per each eye). Once I had perfect sight and I’m very sorry I can’t see as well as before. I study and work at the same time. Does this “work” somehow bring about my sight getting worse? I need clear, distinct sight for my job.

It’s very interesting to notice (and point out) your gradual development of almost all functional visual errors. If you ask anyone who suffers from a refractive error, he is likely to answer,“At the moment I wear –4 diopters, but at the beginning, my first pair of glasses was –0.75” referring to gradual dioptric power change in a negative direction.

Analyzing these simple answers, we can see that each person was changing her glasses constantly throughout the time due to her sight getting worse. It makes us wonder whether the “corrective procedure” works well from a therapeutic point of view, since in almost all cases it doesn’t cure the very problem at all, but even worse, it is contributing to the increase of overaccommodative/near-point stress. This results in decreasing focusing ability over time.

In recent years, medical science has made great steps and presently can treat a huge number of diseases and problems, but in this case of functional visual disorders we should wonder: What has been done for accommodative functional disorders like myopia, hyperopia, or astigmatism? Could we see the indiscriminate wearing of minus glasses and contact lenses as a therapeutic procedure?

Perhaps the present “treatments” for refractive errors should be checked out again from another point of view, which must be less “myopic,” knowing about the importance of the need for effective prevention. When someone’s leg is broken, the first step is to put it in a cast in order to heal the bone. Such a procedure is aimed at allowing the injured person to walk on his legs again. Sometimes he’s also given a pair of crutches to support his body weight and to make walking easier, until his leg is completely healed and the injured person is able to walk again. Keep in mind: The crutches are to be used until the leg is healed and walking is restored—but not beyond that point.

This does not happen in healing the sight by prescribing and wearing minus-lens glasses. Try to imagine a person who goes through a bad time and notices that his sight is getting worse. The person has a feeling of not being able to see well, and that what he could previously see is now blurry. Therefore, he looks for an ophthalmologist who diagnoses him as having low myopia and “heals” him with a pair of minus-lens glasses.

From this moment on, wearing such glasses, even at “near” where he doesn’t need them at all, this person’s refractive error will be getting worse and worse. A “functional error” is one that doesn’t act over the structure of an organ (organic disease) but over the way the organ is used—in this case, wearing minus glasses, or even worse, wearing full correction contact lenses(20/20—Snellen chart, per each eye) over time. When you do this, the visual system will become weak and tired (consequently, higher and higher dioptric power minus lenses will be needed).

In my view, this can’t be the right therapeutic procedure, since it doesn’t remove the initial cause of problem itself, but worsens it over time.

So, we shouldn’t be surprised when we notice that a person who wears full correction in almost all his ordinary activities demonstrates this myopic “propensity” and gradual sight worsening. This type of “minus-lens therapeutic” procedure for refractive errors degenerates the optically overcorrected person into an endless series of newer and stronger minus-lens glasses.

The result: Growing older, the refractive error will, most probably, grow.

The rule “Function makes the organ” doesn’t foresee any exception even in the case of visual organs; natural and physiological focusing ability becomes worse and is “ruined” by wearing full correction (minus glasses and contact lenses), as we do presently. Besides, such a procedure does not act on someone’s personal psychological, emotional, or other additional causes, nor on the stress itself.

Perhaps the reader is under too high overaccommodative stress(working and studying a lot). She might be under other kinds of stress at the same time (remember that the eyes suffer from emotional stress more than other organs), and all this has led to her sight going more negative. However, it could be healed in this initial phase simply by lessening the near-point/proximal stress (viewing in distance and, perhaps, wearing positive “leisure” glasses for all near-work). Besides, it would be very useful to have some break in your ordinary activities and to let yourself relax and rest. If you decide to wear positive lenses, it will reduce nearpoint stress and will improve distance focusing ability. However, you are to wear such plus lenses only when you don’t need full distant correction for safety reasons (for example, driving your car or doing a particular job).
