Traditionally, the plus lens is prescribed for farsightedness and for elderly
people for
reading. A normal eye experiences blurry vision when looking through a plus
lens. A myope experiences even more blurry distant vision with a plus lens --
just like seeing in fog. This is why it is called "fogging".
The main thesis of the site and our book "You are wearing the WRONG
glasses" is the use of reading plus lens for myopia prevention.
For centuries, all myopic children have been fitted with minus (concave)
glasses to instantly make distant objects very sharp. Unfortunately, this
method of treatment for myopia leads to a vicious cycle of myopia degeneration
until you reach maturity.
In fact, the "correction" with a minus lens is a matter of treating the
symptom while ignoring the cause. The minus lens in fact has this serious
secondary effect -- which produces this vision deterioration.
We strongly recommended the use of reading plus-lens glasses for myopia
prevention and treatment. They are to be used for all protracted
near-work.
All myopia goes through the refractive stages of +0.25, plano , -0.25,
-0.50, -0.75, and during this time the public pays no attention to it until it
reaches -1.00D, (6/12) at which time the parent or child recognizes he has
blurred vision in his class.
If myopia (-0.50) can be caught at this early state and the plus lens use
instituted, then recovery and effective prevention is possible. By this
process, the lifetime crutch of minus glasses can be avoided.
Myopes must have and understand patience with this method, since the
effect of plus lens will develop over a period of time. The rate of recovery
may take one or two years for complete return of clear distant vision. It is
an excellent idea to wear the
plus-lens glasses for 1 to 2 years to clear and maintained naked-eye vision
for life.
Even though recovery might not be possible in some cases, the plus lens can
prevent further myopia development. This is
the major goal of plus lens application.
FOGGING with plus lens is further separated into "far fogging" and "near
fogging" techniques.
Near fogging
Near fogging (a moderate plus) is used to
relieve eye focusing muscle partially at time reading, writing and using
computer. With mild nearsightedness, near vision will in factbe seen clearly
through this lens, or only slightly fogged.
Far fogging
A plus (a mild plus) is used to relax eye
focusing muscle completely in distant viewing. The eye is no longer
accommodated with such a lens for distant vision. Tightened focusing muscle
must be completely relaxed in order to see clearly.
Myopia prevention with the plus lens has been advocated and used by eye
care professionals over the past hundred years. It is not a new discovery,
but it is difficult to implement properly.
This technique for early myopia prevention (and cure) can be found in older medical books. Because the method is not fully supported by main-stream eye care professionals, the public is not aware of its existence. For this reason myopia has run wild in the modern literate societies due to the wide-spread use of the minus lens.
The best way to act against myopia is to initiate the strong use of
PLUS lens at the threshold of nearsightedness.
