The degree of myopia getting worse results in two reasons: generally
speaking, children's myopia degree will increase 50 to 75 degrees in one year or
two, and the one of adult will increase 50 to 75 degrees in two or three years.
There are usually two reasons for causing continuous deepening of myopia. One is
pathological myopia in which pathological changes happen within the eyes. It is
genetic, with the manifestation of continuous deepening of myopia and rapid
progress. If myopic degree grows more than 100 degrees within one year, even up
to over 200 degrees, or the myopia which total degree is up to 2000 degrees,
this is maybe pathologic myopia.
There is no effective method to cure pathological shortsightedness nowadays.
At present, the main treatment for scleral staphyloma is scleral reinforcement.
A wide fascial strip is used to hold the posterior sclera in this operation. On
one hand,it strengthens the support force of posterior sclera, preventing the
continuous development of posterior scleral staphyloma.
On the other hand, it will shorten the diameter of eyeball, which, to a
certain extent, can reduce the myopia degree. The other reason is that people do
not pay attention to eye health or have the bad habit of using eye. For example,
lighting being too bright or too dark, looking for too long time, or getting
trichiasis, ptosis, keratitis and other eye diseases which did not be in timely
medical treatment.
With stress of women glasses:Inappropriate
glasses may also increase the myopia. Once you found that your girls eyewear
were not suitable for you, you should check your eyes in normal
hospital to rectify and change your glasses, recheck it regularly. Young people
under 12 years of age, preferably make optometry six months or a year one time,
and you can use omydriasis optometry so that the eyes of the ciliary muscle can
fully relax. It can also eliminate the inaccuracy caused by pseudo-myopia. And
you should timely wear women eyewear to correct. The
adults who's age are no more than 40 years old.
If you are the first optometry, also need omydriasis optometry , and at the
same time need a detailed fundus examination to rule out retinal disease and
conditions such as crystal defects. Paying attention to eye hygiene is very
important. The author thinks "Do not overuse the eyes" is very important on how
to use eyes correctly. When people are growing, the time for eyes is limited.
Excessive consumption will cause pathological change, even myopia.
Someone compared vision to battery in the flashlight, the shorter you used it
at one time, the more times you can use it, the longer its life is. A long-time
application at a time will lead to the shortening of operational life because of
acute consumption. Therefore, the eyes should be given reasonable time of
rest.
Make sure do such points: 1. Keep the time under 6 hours to see nearby
things. 2. When studying, listen more to take place of seeing and reduce the
burden of eyes. 3. It is better to put the desk in a place where no objects are
blocking the window. 4. If you are using a incandescent lamp, 25 to 40 watts
would be much better and the light should not reach the eyes directly 5.
Maintain a sufficient distance from the
