Abstract: the adjustment ability of the eyes in adolescence is very strong, which makes the ciliary muscles tense for a long time. Due to the excessive use of adjustment and eyes, the refractive power of the eyes increases and forms pseudomyopia. Full mydriasis with cycloplegic agent can distinguish false myopia from true myopia., The eyeballs of teenagers aged 7 ~ 18 are not fully developed. In the face of a large variety of electronic products, it is urgent to protect children’s eyes! Parents need to strictly control the use of electronic products and have a visual examination every 2 ~ 3 months, so as to achieve early detection and early treatment; Try to spend more time with your children, go out more, watch the natural scenery and participate in sports. For children to have a clear world, work together., What are the common refractive errors in adolescents?, Expert interpretation: the common refractive errors of teenagers include myopia, astigmatism, hyperopia and anisometropia. Myopia is the most common., How much myopia do you need to wear glasses?, Expert interpretation: in principle, there is no need to wear glasses within 100 degrees, but it should be combined with the naked eye vision. If the naked eye vision can reach 0. 7～0。 8. Do not wear glasses temporarily, but observe closely., What is pseudomyopia and how is it different from true myopia?, Expert interpretation: the adjustment ability of the eyes in adolescence is very strong, which makes the ciliary muscles tense for a long time. Due to the excessive use of adjustment and excessive use of the eyes, the refractive power of the eyes increases, forming pseudomyopia. Full mydriasis with ciliary paralysis can distinguish between pseudomyopia and true myopia. Pseudomyopia occurs when there is no obvious diopter after mydriasis and the visual acuity is improved; If there is a certain diopter after mydriasis and it must be corrected with a lens in order to improve vision, it is true myopia.,
7-18-year-old teenagers’ eyeballs are not fully developed. In the face of a large variety of electronic products, it is urgent to protect children’s eyes! Parents need to strictly control the use of electronic products and have a visual examination every 2 ~ 3 months, so as to achieve early detection and early treatment; Try to spend more time with your children, go out more, watch the natural scenery and participate in sports. For children to have a clear world, work together.
what are the common refractive errors of teenagers? Expert interpretation of
and
: the common refractive errors of teenagers include myopia, astigmatism, hyperopia and anisometropia. Myopia is the most common.
how much myopia do you need to wear glasses? Expert interpretation of
and
: in principle, glasses are not required within 100 degrees, but they should be combined with the naked eye vision. If the naked eye vision can reach 0. 7～0。 8. Do not wear glasses temporarily, but observe closely.
what is pseudomyopia and how is it different from true myopia? Expert interpretation of
and
: the adjustment ability of the eyes in adolescence is very strong, which makes the ciliary muscles tense for a long time. Due to the excessive use of adjustment and eyes, the refractive power of the eyes increases and forms pseudomyopia. Full mydriasis with ciliary paralysis can distinguish between pseudomyopia and true myopia. Pseudomyopia occurs when there is no obvious diopter after mydriasis and the visual acuity is improved; If there is a certain diopter after mydriasis and it must be corrected with a lens, the person whose vision can be improved is true myopia.
why do you check the ocular axis before optometry for myopia? What is the degree value of the normal ocular axis? Expert interpretation of
and
: myopia is divided into axial myopia and refractive myopia, and refractive myopia is divided into curvature myopia and refractive index myopia. Axial measurement can understand whether the child’s myopia type is axial myopia or refractive myopia. At the same time, it can understand the type of children’s myopia progress and select the appropriate correction method according to the type of myopia. Generally, the normal value of ocular axis after 5 years old is 23. 5～24mm。 Can
and
myopia be treated? Expert interpretation of
and
: if it is confirmed to be true myopia, the existing means cannot be cured, but it can be corrected by optical methods, including wearing frame glasses, Corneal shaping lens (OK lens), rigid contact lens (RGP), corneal refractive surgery (after the age of 18), etc. myopia is easy to grow in adolescence. Cultivating correct eye habits and wearing appropriate refractive corrective glasses are recognized methods.
why does the degree of myopia increase, how can the degree of myopia increase be controlled? There are several control methods?
Expert interpretation of
: the growth of myopia is related to the following factors: 1. Genetic factors; 2。 Optical imaging factors, such as accommodation lag related to close eye use and hyperopia defocus of peripheral retina, are easy to cause myopia; 3。 Lack of outdoor activities. Genetic factors are uncontrollable. Wearing progressive multifocal glasses can reduce close-up overuse, and appropriate use can alleviate the progression of myopia. Wearing orthokeratology lens (OK lens) and rigid contact lens (RGP) can reduce the blurred image of peripheral retina, change the imaging position of peripheral refraction, and delay the progression of myopia.
The method of visual training can improve the lag of adjustment function, alleviate the visual fatigue of teenagers, and also alleviate the progress of myopia. Increasing the time of outdoor exercise can also alleviate the progression of myopia. It is suggested that teenagers go to professional ophthalmic medical institutions for detailed examination and choose the corresponding methods to alleviate the progress of myopia.
