Myopia glasses, parents are most worried about these six common problems

Abstract: because the ciliary muscle of children’s eyes has strong regulation ability, it will not relax the ciliary muscle without mydriasis, and the real refractive power may be covered up. Through mydriasis, we can diagnose the types of ametropia, namely myopia, hyperopia and astigmatism, and obtain accurate diopter.

pseudomyopia is functional and mostly occurs in adolescents. Vision can decline in a few weeks or one or two months, and can recover to some extent after appropriate rest. Many parents have illusions that their children are just pseudomyopia.

question 1: why mydriasis?

because the ciliary muscle of the child’s eye has a strong ability to regulate, without mydriasis, the ciliary muscle will not relax, and the true diopter may be covered up. Through mydriasis, we can diagnose the types of ametropia, namely myopia, hyperopia and astigmatism, and obtain accurate diopter.

question 2: is mydriasis safe?

mydriasis does no harm to the eyes. On the contrary, it can also rule out pseudomyopia.

question 3: what is the fast dispersion method?

and

are rapid mydriasis, which are mainly suitable for children and adults. The method is to close your eyes and sit still. The doctor drops the rapid mydriasis solution every 5 minutes. After dropping it four times in a row and resting for 20 minutes, you can do the initial optometry. After mydriasis, it returns to normal 6 ~ 8 hours, and then go for a retest the next day.

question 4: is it true myopia or false myopia?

true myopia is an organic change and cannot recover naturally. If the child’s poor eyesight lasts for half a semester or several months, it is likely to be true myopia. Pseudomyopia is functional, mostly in adolescents. Vision can decline in a few weeks or a month or two, and can recover to some extent after appropriate rest.

many parents have illusions that their children are just pseudomyopia. In fact, to judge whether a child is pseudomyopia or true myopia, you can know by doing one thing: regular mydriatic optometry. After mydriatic optometry, if there is no myopia, the diopter is false myopia, and if there is myopia, the diopter is true myopia.

teenagers must have mydriatic optometry for the first time.

question 5: does myopia need glasses?

once suffering from true myopia, you must wear appropriate glasses for correction. At present, the methods suitable for correcting myopia include frame glasses and contact lenses. For children, wearing frame glasses is a way to correct myopia. There is also a kind of corneal shaping lens worn at night, commonly known as OK lens, which is generally used in children and adolescents in the growth and development period. Wearing glasses at night has a special “shaping” effect on the cornea, which can appropriately delay the progress of juvenile myopia. Parents should be reminded that the fitting of any type of glasses requires professional technology. It is recommended to carry out it under the guidance of ophthalmologists and optometrists.

question 6: can the degree of myopia be reduced?

with the growth and development of children, the diopter of myopia will only increase but not decrease. Teenagers are generally axial myopia. As the eye axis becomes longer, the degree of myopia gradually increases. Generally, for every 1 mm increase in the length of the eye axis, the degree of myopia will increase by 300 degrees. In adulthood, the degree of myopia can be stabilized within a certain range because the axial length of the eye is no longer increased. No method can make the lengthened eye axis shorter and lower the degree, but we can control it.

how to correctly fit corneal shaping lens?

1. Corneal shaping lens must be checked and matched in medical institutions above grade II;

  2、 Doctors and technicians (optometrists) for fitting corneal shaping lenses must have intermediate titles or above, and must be completed with the cooperation of ophthalmologists;

3. The fitting process of corneal shaping lenses is rigorous, and they can only be matched after strict ophthalmic examination, medical optometry and trial wearing;

4. The State Food and drug administration stipulates that at present, China has approved the listing of corneal shaping lenses with a maximum corrected diopter of 500 degrees, and requires that the description of such products must be marked as prohibited for children under the age of 8.
