- Recently we were invited into one bank
check whether the computers have harmful effects on health
staff - told the doctor of technical sciences, head of the
Testing Center "Elita", acting at the Moscow State
Institute of Electronics and Mathematics, I. Litvack.
- The results are simply discouraging:
electromagnetic and electrostatic fields on the order of magnitude higher than the norm,
computers themselves in terms of lighting conditions, posted illiterate,
required distance between them is not met, the whole screen
not protect against radiation.
word violated many asles of
PC, which, unfortunately, the staff just do not know.
The results of our audit, on the terms of the agreement were confidential,
reported only the bank's management. It is initially expressed concern
about the health of its staff, but then, as we learned,
very original take care of it - to raise the salary by 10%.
It's easier and cheaper than putting things in order.
This is an example of how not to better characterize
the current situation with Russia's landslide computerization. In the country
nearly 5 million PCs annually and their number
increases to about 500,000. Moreover, imported and marketed
mostly outdated foreign equipment that does not meet modern
safety standards. And the saddest thing that users are still
far really do not know the basic asles of work on the PC, on health
asles and their rights.
In the West, if a person settles
work at the firm, all of this is stipulated in drafting employment
contract. There, in particular, written safety regulations,
Payment in terms of vacation time, breaks, etc.
We also like that while it sounds like
Fiction. All disease ... of view of main conclusion
workshop participants - scholars and the Russian Academy of Medicine
Sciences, State Standard of experts, the Testing Centre of
display and other organizations - that sounds quite unexpected:
electromagnetic radiation of a personal computer, if it
does not exceed acceptable standards, no negative influence
on our health.
- In any case, the unique relationship
between the presence of electromagnetic fields and specific diseases
is not set - said Yu Z. Rosenblum, MD,
Head of the Laboratory of the Institute of Optometry and oftalmoergonomiki
Eye Diseases. Helmholtz. - What confirms World
Health Organization. But how then to be numerous
articles alleging that PC users are complaining
headache, fatigue bystronastupayuschuyu, even the appearance
symptoms of cardiovascular, nervous, gastrointestinal and other
disease?
turns out that's all my fault, as
Paradoxically, the vision. When it works with large congestion
then comes the total exhaustion of the body, which is equivalent stress.
Hence - and headaches and fatigue. If prolonged stress,
occurs when the weakest link in the chain breaks: they can
aggravate an ulcer, the other crashes of cardio-vascular system,
at the third - and so nervous Derivation of the participants is clear:
to preserve the health, it is necessary to reduce eye strain.
But today it is already so high
that traditional measures - regulation of lighting in the room selection
optimal brightness and contrast of the screen, etc. - Is not enough.
So scientists are advised to use a computer with special glasses
color filters, developed by the Institute of Biochemical Physics
im.Emanuelya conjunction with the Institute of Ophthalmology im.Gelmgoltsa
and Moscow's optical business, "Lornet-M. Let us say at once:
These points have nothing to do with the products, which today
littered the counters.
best of what is sold is capable of
only reduce glare, which, incidentally, are removed by means of modern
protective screens and through the use of displays, with special
anti-reflective coating.
- Generally it is a fundamentally
new direction in ophthalmology - a spectral vision correction
- Said the director of "Lornet-M PE Golikov. - To understand
casx of the matter, let us remember how the eye. It is a huge
number of different functions of the photoreceptors, perceiving
luminous flux. Having its own specifics, but working together, they
provide a body of remarkable versatility: the eye
sees in the dark and in bright light, sees in black and white
and differentiates subtle shades of different colors, etc. But always
whether similar versatility is needed?
turns out to perform many
works with, say, documents or computer is sufficient,
to operate a small number of photoreceptors. Rest
can provide the rest. How? Mechanism in principle is clear. Eye
takes the so-called primary colors - red, blue and
green. Their confusion and makes the whole color palette. Each main
color is characterized by its range and spectasm of wavelengths. And
to a certain, very narrow portion of this range, photoreceptors
have the greatest sensitivity.
imagine that with a special
filter was of the full range of colors to allocate it
this site and send in the lens. Now it gets already
not all of the color flow and, consequently, reduced eye strain,
and color perception will remain almost the same level. Many
readers, apparently realized that this is very similar to the selection
signal in the radio. To accept a certain purity,
apply filters, cutting other frequencies. Only in opticians
task much harder, because we have to deal with the wavelengths
10-9m, which is much smaller than in radio.
to fix it for many years were broken
head in the laboratories of many countries, and the first to succeed
Russian scientists and engineers. They were able to identify specific boundaries
or "window" of maximum spectral sensitivity of the eye, picked up
composition of materials with the appropriate parameters transmission.
Finally, we developed a technology for applying such materials on
lenses. But that's not all. The fact that the emission spectasm of phosphors

points, producing a correction of the radiation,
make the colormorenatural, improve image quality,
prevent the development of myopia. Created by our experts

By the way, describes the principles can be
making and other specialized filters - for motorists
for sun protection, treatment of various diseases, etc. With their
help get straight yet paradoxical effects. Say, reduce the
luminous flux, reducing eye fatigue many times, and a man
it seems that light, on the contrary, increased.
