Abstract: mydriasis can help the optician determine whether there is pseudomyopia, adjust the far and near visual refraction of the eye, and the eye has the ability of self-regulation. Therefore, even patients who have been myopia for many years may have pseudomyopia., Every summer is the peak period of student lens matching. When the child is nearsighted, the first reaction of parents is to equip the child with glasses. However, after a period of time, it is often found that children’s myopia is not controlled, but deepened. Why does the degree deepen after glasses?, Reminder 1: all kinds of optical parameters are very important. A pair of qualified and comfortable glasses depends on two factors: one is whether the optometry is accurate, and the other is whether the glasses preparation is qualified. In addition to accurate optometry, various technical parameters should be met when matching glasses. For example, pupil distance is one of the keys to prepare qualified glasses. Inaccurate measurement of pupil distance is easy to cause many problems such as deviation of optical center distance and vertical deviation of optical center. Wearing such glasses will not eliminate visual fatigue, but will cause visual object deformation, reduced definition, even dizziness, nausea, vomiting, eye swelling, etc., Reminder 2: materials, production and optometry are equally important. After optometry in formal medical institutions, some consumers often buy glasses in other places with optometry degree in order to buy cheap glasses. Here, we need to remind you that glasses materials, production and optometry are equally important. Therefore, it is best to match glasses at the same time after optometry in professional institutions to ensure the quality of glasses., Reminder 3: mydriatic optometry is one of the important steps in medical optometry. Mydriatic optometry can help optometrists determine whether there is pseudomyopia, adjust the far and near visual refraction of the eyes, and the eyes have the ability of self-regulation. Therefore, even patients who have been myopia for many years may have pseudomyopia. For myopic patients with stable vision but decreased vision recently, and students who have just experienced heavy learning, do not ignore the step of mydriasis before fitting glasses, so as to eliminate false myopia. Generally speaking, children under the age of 12 usually have to dilate their pupils for 3-5 days before they can wear glasses, and it takes about 60 minutes for others to dilate their pupils., Reminder 4: it’s better for students to wear glasses with resin.
is the peak of students’ glasses every summer. When the child is nearsighted, the first reaction of parents is to equip the child with glasses.

reminder 3: mydriatic optometry is one of the important steps in medical glasses.
mydriatic optometry can help opticians determine whether there is pseudomyopia, adjust the far and near visual refraction of the eyes, and the eyes have the ability of self-regulation. Therefore, even patients who have been myopia for many years may also have pseudomyopia. For myopic patients with stable vision but decreased vision recently, and students who have just experienced heavy learning, do not ignore the step of mydriasis before fitting glasses, so as to eliminate false myopia. Generally speaking, children under the age of 12 generally have to dilate their pupils for 3-5 days before they can wear glasses, and the time for others to dilate their pupils takes about 60 minutes.
reminder 4: it is better for students to wear glasses or resin
at present, all kinds of optical resin lenses have been widely used in ophthalmic clinical glasses preparation. Their advantages are light material, strong resistance to all kinds of radiation, clean surface, easy protection, wear resistance and scratch resistance. They have high light perspective index and high refractive index, and are safe The impact resistance is also very high. Among them, PC resin materials have high toughness and excellent protection ability. They are called “unbreakable and unbreakable” glasses optical materials, and their impact resistance is more than 10 times higher than that of ordinary resin lenses. As children and teenagers are more active, it is recommended to use resin lenses when matching students’ glasses.
children with myopia often have the following manifestations:
when looking at distant objects, they often narrow their eyes, otherwise they can’t see clearly;
the distance between reading and watching movies and TV has become closer, especially when watching TV, I always like to be close to the TV;
and
tend to frown when looking at objects.
should check the eyes in several stages:
1-3 years old: ask a doctor to have a simple eye and vision examination.
3-5 years old: visual acuity examination (naked vision is normal only when it is more than 0.6).
before primary school: check your eyesight and check for ametropia, strabismus and amblyopia.
and
students (6-18 years old): do regular visual examination every six months.
