Children with myopia must not match glasses indiscriminately. Be sure to check the “true and false” first!

Abstract: mydriasis does no harm to the eyes. Only in a small part of the population (mostly the elderly) due to abnormal eye anatomical characteristics, mydriasis leads to high intraocular pressure and induces the onset of angle closure glaucoma, but it is very rare in children. Why does

have mydriasis?

mydriasis will be safe? Is


faster than slower?

will my child be pseudomyopia?

does myopia need glasses?

can eye protection reduce the degree of myopia?

parents with these questions are definitely not a few

to listen to the answers of the eye hospital!

question 1: why mydriasis?

first of all, we should clarify the role of mydriasis. Because the ciliary muscle of children’s eyes has a strong regulatory ability, not mydriasis will paralyze the ciliary muscle, and the true diopter may be covered up.

therefore, mydriasis can not only diagnose the types of ametropia (i.e. myopia, hyperopia and astigmatism), but also obtain accurate diopter.

question 2: is mydriasis safe?

mydriasis does no harm to the eyes. Only a small number of people (mostly the elderly) have abnormal anatomical characteristics of the eyes, High intraocular pressure caused by mydriasis induces the onset of angle closure glaucoma, but it is very rare in children.

question 3: just disperse quickly? Slow dispersion is not good?


are called “rapid mydriasis”, which are mainly suitable for older children and adults.


are called “slow mydriasis”, which are suitable for young children, especially those with hyperopia, astigmatism, strabismus and amblyopia.


are not good or bad. It depends on the child’s age and actual eye conditions!

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 and mostly occurs in adolescents. Vision can decline in a few weeks or 1 ~ 2 months, 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! That is – regular mydriatic optometry!

after mydriatic optometry,


have no myopia. The diopter is pseudomyopia.

if there is myopia, the diopter is true myopia.

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 the main way to correct myopia. Contact lenses are divided into soft and hard. What we contact most is soft, which needs to be worn during the day.


hard glasses are divided into two categories: one needs to wear RGP to correct vision during the day and the other needs to be worn at night; Contact lenses worn during the day mainly play the role of correcting vision similar to frame glasses; The glasses worn at night are called corneal shaping glasses. They are generally used in children and adolescents in the growth and development period. They play a special “shaping” role in wearing glasses at night on the cornea. They can effectively control the progress of juvenile myopia and restore normal vision during the day.


need to remind parents 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 eye care reduce myopia?

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. Any method can not make the lengthened eye axis shorter, so eye protection will not reduce the degree of myopia, but only alleviate fatigue.

question 6: how can we effectively alleviate the growth of myopia?

keratoplasty is one of the effective methods to control the progress of myopia.

keratoplasty is a very effective non-surgical correction of myopia. It changes the curvature of the anterior surface of the cornea by wearing it at night, and has clear vision without wearing glasses the next day. It is recognized as one of the effective means to control the development of myopia because it can improve visual quality, effectively remove peripheral retinal blurred images and inhibit the growth of ocular axis to a certain extent.

warm tips

1. Some children will have symptoms such as red face, fever, eye discomfort and rapid heartbeat after using atropine. Generally, they can subside by themselves without worrying too much. If you feel unwell for a long time or have fever above 38 ℃, please stop taking the medicine and see a doctor.

2. Children will have photophobia and other symptoms during mydriasis. They can wear sunglasses to protect them when going out.

3. Once diagnosed as true myopia, it should be corrected. Wearing glasses that meet the diopter can not only correct vision, alleviate eye fatigue, but also prevent the excessive growth of diopter.

4. For small patients with ordinary myopia, optometry is generally required every six months to one year, and mydriasis optometry is required every time in order to obtain the true diopter.
