Myopia in children can be corrected, but this correction simply brings the child's vision to a normal level and does not mean that true myopia can be reversed. Myopia can be divided into true myopia and false myopia. False myopia can be restored to normal vision through appropriate rest and a series of relieving recoveries. However, if diagnosed with true myopia, there is currently no method available to reduce the degree of myopia and restore the child's normal vision. Moreover, once true myopia occurs, it will not stop and typically increases every year until the child reaches adulthood, when it gradually stops. Therefore, before the child reaches adulthood, it is worth considering using methods such as wearing glasses and developing good eye habits to control the increase in the child's degree of myopia and to achieve the purpose of correcting the child's vision.

At what degree of myopia do you need to wear glasses?

Myopia is a refractive state in which, when the eye's accommodation is relaxed, parallel light rays from the outside, after passing through the eye's refractive system, focus in front of the retina, this condition is called myopia. The occurrence of myopia is influenced by a combination of various factors including genetics and environment. Common clinical symptoms of myopia include decreased vision, which also affects normal daily life. It is recommended to wear glasses regardless of the degree of myopia if it impacts daily activities.

What is the uncorrected visual acuity of high myopia?

Myopia can be classified as mild myopia from 200-400 degrees, moderate myopia from 400-600 degrees, and high myopia as above 600 degrees. What is the uncorrected visual acuity for high myopia? There is no clear pattern for this because a visual acuity of 0.1 may be corrected to 1.0 with just 50 degrees, or it might not reach 0.5 even with 1000 degrees. Therefore, uncorrected visual acuity is not a standard measure for high myopia. The level of uncorrected visual acuity depends on the condition of the eye's axial length and diopter. If the change in the axial length is not significant, a minor uncorrected visual acuity is not crucial, and the required correction might be very low. Conversely, the longer the axial length, the higher the correction needed might be.

Does nearsightedness surgery require hospitalization?

Myopia surgery does not require hospitalization; it is completed on an outpatient basis. Before the surgery, routine blood tests, screenings for infectious diseases, and specialized eye examinations are conducted. If the pre-operative examinations are thorough and there are no contraindications for surgery, the procedure can be performed on an outpatient basis. After the surgery, patients can go home and must return to the surgical hospital the next day for a follow-up examination. Post-operative medication should be used as prescribed by the surgeon, and regular follow-up appointments should be scheduled.

Can 600-degree acquired myopia be inherited?

A myopia of 600 degrees is considered high myopia, and it can be inherited by the next generation. Moreover, eyes with high myopia are prone to other complications at the back of the eye, such as retinal breaks, macular holes, and posterior staphyloma. Therefore, it is crucial to pay attention to high myopia and have regular check-ups. If both parents have high myopia, there is an 80% chance that their children will tend to be myopic. If one parent has high myopia, there is a 50% chance that their children will tend to be myopic. Even if neither parent is myopic, there is still about a 20% chance that their children will be myopic.

Is a child's vision of 4.7 considered nearsighted?

Children's vision at 4.7 does require a comprehensive analysis to determine if they are nearsighted. Generally, a child with a vision of 4.7 is likely to be nearsighted, but this single parameter should not be used to diagnose myopia. It's necessary to differentiate whether the child has true myopia or false myopia. Additionally, the issue could be amblyopia, astigmatism, or farsightedness. Moreover, the child's age also plays a significant role in assessing vision. For instance, a vision of 4.7 might indicate nearsightedness in a child aged seven or eight, but for a child around three years old, a vision of 4.7 is considered normal. Parents are advised to take their child to the hospital for a dilated refraction test to ascertain the specific condition.
