With the diversification of video terminals and the increasing pressure of learning among teenagers, the incidence of myopia among teenagers is increasing year by year. The impact of myopia on adolescents is self-evident, as it affects learning due to blurred vision, visual fatigue, aesthetics due to skewed eye position, and even amblyopia. Therefore, it is necessary to master the science of myopia correction method, today mainly to talk about the correction method of myopia. Medical optometry To solve the problem of myopia correction, you must first undergo a medical optometry to confirm whether it is pseudomyopia or true myopia, to determine the best prescription for glasses, so that the wearer can see more clearly, see more comfortably, and see more permanently. Medical optometry steps will not be detailed, in the medical eye doctors will pay special attention to the following 7 issues, if you go to the hospital or opticians do not have these links, that your prescription is likely to be inaccurate. 1, pay attention to the ophthalmic history inquiry and eye examination, through the medical history inquiry, can understand the patient’s past prescription, eye habits, etc., eye examination can rank whether the patient has other eye diseases, such as corneal disease, cataract, fundus disease, so that the patient can get the best treatment. 2. Check the dominant eye (primary eye) to keep the same before and after wearing the lens. Changing the dominant eye before and after the prescription will make the patient have to readjust to it, thus creating an uncomfortable feeling. 3, must check the eye position, because the eye position determines whether the prescription is undercorrected or overcorrected, in general, the internal oblique myopia is undercorrected, the farsighted eye is fully corrected, the external oblique myopia is fully corrected, the farsighted eye is fully corrected. 4. Adjustment power is also an indicator that must be measured. Usually, if the adjustment power is strong, the myopia will be undercorrected, the hyperopia will be overcorrected, and if the adjustment power is weak, the opposite will happen. 5.Check the visual function of both eyes, especially when the degree of both eyes are not equal, must pay attention to the balance of both eyes. 6. Pay attention to the astigmatism axis, accuracy is necessary, in addition, parsimonious astigmatism is generally undercorrected, retro-regular astigmatism or oblique axis usually must be fully corrected. 7, accurate measurement of the pupillary distance, in order to maintain the center of the visual axis of both eyes and the optical center of the glasses consistent. Myopia correction methods can be divided into two categories: non-surgical methods and surgical methods in the general direction. Since adolescents are under 18 years old and their eye conditions are not fully developed and stable, we mainly introduce non-surgical methods. Non-surgical methods Frame glasses – is the simplest and most affordable method of correction for adolescents, and is currently the primary method of myopia correction. The advantage is that they are convenient and affordable, but the disadvantage is that they affect the aesthetics and movement, and they shrink the image. Corneal contact lenses are divided into soft corneal contact lenses, which are often referred to as contact lenses, and rigid oxygen permeable corneal contact lenses, or RGP, which make up for the shortcomings of frame glasses and can stop the development of myopia to a certain extent. lacking. Corneal shaping lenses are the only effective way to improve naked eye vision without surgery, and can be worn at night without glasses during the day, and can effectively control the development of myopia in youth.
