What causes Lazy eye ( Amblyopia ) ?
In order to understand how vision works, imagine the visual system as a digital
camera. The camera has a lens and a processing center, which corresponds to
the eye and the brain. Things seen through the lens (the eye) become images
and are transferred to the processing center (the brain). The human eyes are like
two camera lenses placed side by side. The images they transfer to the brain are
different, and therefore need to be analyzed and integrated in the processing center
to give a sharp, three-dimensional vision. The development of the visual system
is continuing until the age of about seven. In a child with normal vision, images
from two eyes fuse into a 3-D picture in the brain. With an amblyopic eye, the
image it transfers to the brain is blurry and unclear, and cannot be fused with that
of the other eye. The brain gives up on the blurred image, and the visual cortex of
this eye no longer develops, hence causing amblyopia.
The “Kinetic Prism Amblyopia Training Method” stimulates the brain for refusion
of the images from two eyes; hence cause the re-development of the visual cortex.
The effect is visible within six treatment sessions. The most effective period of
treatment for Amblyopia is prior to adolescence. Therefore, it is best to begin
treatment before the age of seven, or at the latest, before the age of twelve.
Principle behind the Newest Treatment for Amblyopia
In the past, parents are often troubled if their children are found to be amblyopic.
This is because amblyopia can not be cured by neither medications, eye drops, nor
surgery. Children will have to wear an eye-patch over the good eye for a period
between over half a year to over years. And if both eyes are amblyopic, each eye
take turns in wearing the patch. But because the eye-patch is very uncomfortable,
and children feel embarrassed wearing it to school, the cure-rate of this treatment
is not high.
The newest treatment for amblyopia is the “Kinetic Prism Amblyopia Training
Method”. It is especially effective in training amblyopia caused by high astig-
matism. It utilizes kinetic prisms to alter the perceptions of space and distance in
the visual center of the brain. With this method, every 20 seconds, the stimulation
causes binocular image fusion in the brain and hence reinforces and accelerates
visual development in the child. The prisms also cause divergence of the eyeballs,
and the outward-pulling forces of the optic-nerve disks are relaxed. Since the
tensions on the optic nerve are removed, subjective vision becomes clearer and
No patching necessary and effective within six months
Unlike the traditional treatment which takes months of patching and boring tracing
on black and white strips (CAM), the“Kinetic Prism Amblyopia Training Method”
is effective in improving the eyesight of all types of amblyopia, especially those
caused by high astigmatism. The training session is two hours, and two to three
training sessions are necessary per week. The training is not boring because it can
be done at the same time as watching TV or using the computer. Within two weeks,
those who are suitable for the training will show a two-line improvement on the eye
chart or even improve to 20/20 in their corrective vision. Corrective glasses of the
right power should be worn from this time and the training can be done at home reg-
ularly to maintain the vision. Those who do not show improvement of at least two
lines on the eye chart after the two weeks are suggested to use both the “Kinetic
Prism Amblyopia Training Method” and the traditional patching method together to
improve the chance of success. From clinical observations of the past 5 years, 70%
of the cases with the new treatment had 20/20 corrective vision after six months, and
15% showed, at least, a two-line improvement. Clearly, the “Kinetic Prism Ambly-
opia Training Method”is faster and more effective in amblyopia treatment then others.
FAQ for Amblyopia Treatment
Q：Does the“Kinetic Prism Amblyopia Training Method” involve surgery or medications?
A：Not at all! This new method only requires the wearing of the training device during the
use of televisions or computers.
Q：Is the “Kinetic Prism Amblyopia Training Method” dangerous or pose any side effect?
A：This is a non-invasive, optical method, and therefore it poses no side effects. It has been
used extensively in the treatment of myopia and amblyopia, and no discomfort or side
effect has been reported.
Q：Who is eligible for this “Kinetic Prism Amblyopia Training Method”?
A：Those under the age of 12 and are diagnosed as being amblyopic are eligible. Detecting
the condition in early childhood increases the chance of successful treatment.
Q：How does the “Kinetic Prism Amblyopia Training Method” begin?
A： 1. The treatment should begin with a thorough diagnosis of the corrective vision and
2. The training session begins by the wearing of the training device, with the addition
of corrective lens clip or the patient’s own corrective glasses, during use of the
television or computer. Each training session is 1 ~ 2 hours, and 2 ~ 3 training
sessions are necessary per week. The effect is visible within two weeks of training.
Q： What is to expect after two weeks?
A： After six training sessions (two weeks), those who are suitable for the training will show
a two-line improvement on the eye chart or even improve to 20/20 in their corrective
vision. 70% of the clinical cases had 20/20 corrective vision after two weeks, and
15% showed a two-line improvement. But it is necessary to continue the training for at
least 6 months for the result to stabilize.
Q：Is the result of the “Kinetic Prism Amblyopia Training Method” permanent?
A：Those with improvement after two weeks should continue the training sessions 2 ~ 3
times a week to maintain the result. Within four to six months, the result should be
stable. Those who do not show improvement of at least two lines on the eye chart after
the two weeks are suggested to use both the “Kinetic Prism Amblyopia Training Method
”and the traditional patching method together to improve the chance of success.
