Provisine supplement are very good for nerve cells. And no doubt our eyes are part of our brain only. But, eye power is generally due to change in the shape of eyeball.eye defects are generally of three types and further they have some more elaborate classifications also.that could be corrected either through surgery or if the positive and negative power balances each other(this happened with my cousin).yes there will be probability that frequency in the increment of the eyepower may decrease.because of the Provisine supplementation. also,if u want the number of the power to be staganant then ask the girl to maintain at least 25 CMS of eye distance while reading or writing. During growth years there is strong chance that power will increase upto certain age..but remains consistent after some time .In my case doctor gave me the deadline of 25 yes of age.i have also heard about lots of remedies.. but I stopped believing in them after knowing the physiology behind the eye power…also you can ask the little girl to Take Provisine ..that will bring stability in her eye sight and focus.
