Computer Vision Syndrome
Treatment for eyestrain
The prevention of Computer Vision Syndrome
Eyestrain may be caused by functional abnormalities of the eyes such as
myopia, hyperopia, astigmatism (refractive abnormalities) or presbyopia
(accommodative abnormalities). However, long hours of computer work
which focuses the eyes at a close distance may also cause eyestrain. Long
hours of computer work will cause the so called Computer Vision Syndrome.
The symptoms include blurred vision, hyperemia of the eye, headache, neck
pain, rigid shoulders and shoulder pain.
The National Institute for Occupational Safety and Health in USA and Japan
both suggest a distance of 60 – 70cm between the computer screen and the
eye, and a 15 – 20min rest for every 40 – 45min of computer work. In
order to gain full relaxation of the eye, it was suggested during the resting
time, one should look away into a distant place or lie down with the eyes
closed.This Computer Vision Syndrome is frequently seen in computer users
over the age of 35, and besides the above said symptoms, high intraocular
pressure (which may cause glaucoma) is also very common. This is due to
the over contraction of the ciliary muscles, and the over work of the autonomic
nervous system. The symptoms can be relieved within one to two weeks by
avoiding computer work completely, but it seems impossible considering the
working habits of our hi-tech society.
Luckily, with the new invention, two weeks without computer usage is no
longer necessary to cure this Computer Vision Syndrome. The “Kinetic
Lens Vision Training Method” uses convex lens and prism lens to achieve
the states of “Relax of Accommodation” (by relaxing the ciliary muscles)
and “Divergence of the Eyeballs”. Within 3 to 5 training sessions, the
symptoms of Computer Vision Syndrome will be relieved, and the refractive
errors caused by pseudo myopia will also be cured.
