Modern
students sit at the computer a lot and move a little
And if
they also spend their free time watching television, vision loss cannot be
avoided.
Myopia
can begin at any age and even be innate, but the most rapid progression of her
case in the age of 11-14 years, in the period of active growth of the child. The
earlier the onset of myopia, the worse the prognosis, that is, more is its
value to 17 years. According
to statistics, only 10% of children are not progressing myopia, the rest is
blurred vision rapidly - in some cases by 1-2 diopters per year.
Treatment Effect
Back
view, if myopia has already occurred, it is impossible. After all, what is the short-sightedness? This excessive growth of the
eyeball. A
child is born with hyperopia, ie "short eyes", but with the growth of
the body grows and the eyes. Ideally
stock farsightedness should be enough to to 16-18 years eye stretched to the
normal range. But
if something goes wrong eye growing too fast and this is the growth of myopia.
As
long as the child grows up with it "grows" and its short-sightedness.
You
can only try, if not stop, at least slow down the process. It
was on slowing the progression of myopia and its complications prevention and
treatment directed to teenagers.
Without glasses does
Myopia
necessarily adjusted - even with a small "minus" image loses clarity,
the child is uncomfortable. European
ophthalmologists recommend adjusting even a quarter diopter. We prescribed
for the correction of myopia of more than 1 diopter.
The main
method of correction are glasses, well-chosen. Almost
all children revealed the weakness of accommodation - adaptive functions for
the eyes at close range, so, for example, reading glasses "to give"
them uncomfortable. For
this reason, children may appoint a bifocal (two foci - for distance and near),
and more recently, the "progressive" (multifocal) glasses. In Research Institute. Helmholtz
recently developed a method of selection of such glasses for children. It
turned out that a properly fitted glasses allow retard the progression of
myopia.
If a
child is involved in sports or just very active and need to wear glasses all
the time, you may want to think about contact lenses.
What to choose?
In
addition to traditional points today, there are many other methods of vision
correction. How effective are
they?
Soft contact lenses. Especially
effective and even essential for the correction of congenital and unilateral
myopia in children. Also,
they can recommend to children active and involved in sports.
Night lenses - orthokeratology (OK-lens). During
the night they gradually change the shape of the cornea, making a flatter
optical zone. During
the day, the cornea retains the acquired form, and the image focused on the
retina, like a man with a perfect vision. By
evening, the cornea returns to its previous, short-sighted form. The
lenses are made of polymeric materials, they also have a diopter is selected
using the visual acuity in children. In
some cases, night lenses can significantly inhibit the growth of myopia.
Perforating glasses. This
glasses simulators that are on the plate a few holes 1-2 mm in diameter. When
the eye is looking through the small hole, the pupil narrows and the magnitude
of the focal length increases. However,
the child will be good to see, as long as these glasses as soon as they
withdraw - the visual acuity will be the same.
Eye drops with atropine - a substance that is
instilled in the eye by a routine examination to improve pupil. According
to studies, regular instillation of atropine eyeball does not increase, that
is, short-sightedness is not growing. True,
there is a side effect of atropine - it degrades the focus at close range, and
the child will have to read the book already in glasses "for near
vision." This
method was thirty years ago popular in recent years because of its side effects
hardly applicable.
Scleroplasty. This
procedure is recommended if vision continues to fall by 1-1.5 diopters per
year. Its
essence is this: in the eyeball, a special plate which prevents the further
growth of the eye. Moreover,
it also has a therapeutic effect: promotes vascular eye sclera improves power,
thereby strengthening it.
Badminton instead of a computer
And
still have a smaller sit at the computer and other electronic gadgets. Our
visual system is not geared to considering pictures on the computer. The
image on the monitor glowing consisting of individual dots
- Pixels,
not in the book - from the solid lines to the same picture on the computer
continuously blinks. Reading
these signals - an enormous burden for the eyes. So that the
printed text - preferably electronic.
And to
compensate for the rest of the books physical activity. Sports,
games, dancing, walking in the fresh air - all this is slowing the progression
of myopia.
- The
last two years we do monitor the impact of regular exercise on badminton for
myopia, - says Elena Tarutta. -
These activities lead to increased accommodation (the one that needs to read
and because of the poor performance which begins nearsightedness), improves
blood flow to the eye tissue. When
the eyes are on constantly moving ball or shuttlecock, there is a natural
training accommodative muscle, providing clarity of vision.
