How to stop/retard myopia progression
(How to save your vision from deterioration)

If you have been wearing glasses for several years and over
-3.00 D, you probably have a case of axial-length myopia. It is
impossible to shorten the elongated eyeball with the fogging-method (plus lens) to reverse this myopia. However, the lens is significant to prevent further myopic development as well as to reduce some part of your myopia over a period of time.
Acquired myopia appears in school children of 7 to 9 and
progresses with age. Almost every myope has gone through the agony of changing minus-lens glasses yearly during the course of elementary and secondary school.
The reason behind this threshold-myopia is that the eye at
this young age is still developing. The layers of eyeball coating
are relatively fragile compared with adult eye. Minus-lens glasses are given to children on the threshold of nearsighted and they are encouraged to wear them all the time.
Near point stress is significantly increased when the minus
lens are worn at near work -- causing rapid vision deterioration,
that is then followed by eyeball elongation.
Generally, myopia stabilizes after reaching maturity by age
In order to avoid getting into high myopia (over -6.00 D),
myopes should adopt preventative measures (how to prevent
nearsightedness) designed to relieve near point stress.
Myopia is a natural (physiological) process that the eye uses to adapt to the excessive near focal environment. It develops because of the way you use your eyes, and is much more prominent in young people.
The simplest way to avoid near focal environment is to give
up all reading or any close work. This is impracticable in our
modern world requiring literate and educated citizens.
Fogging with plus lens is an alternate method that allows the
near focal environment to be moved "into the distance". This
process "relaxes" the and removes the stress of prolonged close work. The method is simple, easy and economic.
Method should be implemented with incipient Myopes below -3.00 D. These children should take off their (minus-lens) glasses for any near work.
Why? The glasses are provided for use at distance 20 feet
and greater. You can figure out how tired the eye becomes if you use the minus-lens glasses at any distance shorter than 20 feet --especially at 1 to 2 feet when doing near work. It is the major reason accounting for your you vision shows rapid vision
deterioration when wearing these glasses. This is especially true in young children.
Myopes over -3.00 D should consider two pairs of glasses. One for far and the other for near. The full power one is for emergency or driving. The other one should be reduced by 1 to 2 diopter for comfortable near work. You will not experience too
much tiredness and fatigue with the use of the reduced prescription glasses -- after your whole-day work in front of a
It is simpler for contact lens wearers to put on a pair of plus-lens (+1.00 to +2.00 depends on situation) glasses any time you are doing near-work. Such glasses have a magnifying effect and you will see will everything larger. The stress caused by the intensive near-work is greatly reduced by the use of the plus in this manner.
Patience and persistence is a crucial factor in using the plus-lens glasses.
I am a high myope wearing contact lens. I have been using
plus lens all the time during my work since 2001. I am a journalist which involves doing a great deal of computer work as a relatively close distance. My prescription has been reduced from -15 D to -14 D in the past two years of doing this prolonged close work.
I sincerely recommend that all myopes who use their eyes a lot for near-work, seriously consider plus lens for prevention.
