Just after the start of the school season, I have to summarize some common phenomena of student glasses. The student glasses we are talking about here include young children, aged 3-18 years old. The student's vision problem is basically a problem of refractive error. Refractive error content is mainly myopia, hyperopia, astigmatism. Some of these children are wearing glasses for the first time, and some are re-reviewing the degree.
Below we will say that parents often ask a few questions from Xiao Yu.
Q1: My child's myopia is not because of my younger age. I have not worn glasses. I usually give my child eye drops before the optometry. The purpose of dilation is to paralyze the ciliary muscles, relax and adjust, thus resulting in the most realistic vision. Therefore, the myopia detected after dilation is true myopia, not pseudo-myopia. It is enough to do it once, and you don't have to do it every time.
Q2: Doesn't it mean that wearing glasses can “correct” myopia? Why is my child's myopia still increasing? This is a relatively common cognitive misunderstanding. The function of the glasses is to correct the refractive error, and to make up for the defects of the human eye's refraction through professional and precise optical lenses, so that people can see things clearly. (Alber Vision) thus protects the eyes from the correct use of the eyes. A big change has taken place. Glasses are used to correct refractive errors, not "corrected."
Q3: Children rarely play mobile phones and watch TV. Why is myopia increased? The root cause of myopia is improper use of the eye. The main situation is that the eyes are used for a long time at a close distance, the illumination is insufficient, and the posture for reading a work is not correct.
Q4: Can children still wear glasses later? Once the refractive error is discovered, it is recommended to perform the correcting of the optic as soon as possible. Myopia can lead to farsightedness. 3 to 8 years old is a critical period of visual development. If the refractive problem is not corrected during this period, there is a risk of amblyopia.
Q5: Is the child's glasses stopped and worn, or is it always worn? How to wear a mirror, we must consider vision and eye position, for each person to analyze. In the absence of eye position abnormalities, low-degree (within -2.00 degrees) myopia, you can look at the distance to wear a mirror, look at the near is not wearing, in principle, look at things blurry wear glasses. Medium-high myopia suggests wearing glasses all the time. When myopia is accompanied by an external oblique, the degree of myopia is always worn regardless of the number. For the hyperopia of the medium height, you must always wear a mirror. When the astigmatism is >0.75D, it is also recommended to wear the mirror all the time.
Q6: What problems should children pay attention to after wearing glasses? After wearing glasses, myopia children should pay attention to the time of using the eyes at close range. Control the time of writing, less contact with electronic products, more outdoor activities, more exposure to natural light, and choose a table lamp that is close to the natural spectrum.
