Myth 1: The more you wear glasses, the deeper they get? Many people believe that wearing glasses will cause myopia to deepen. In fact, the cause of myopia deepening is mainly related to eye distance and continuous eye time, and not much related to wearing glasses. Myopia in adolescents deepens faster, mainly due to the fact that children of this age are in the growth period, growing taller, and their eyes are also developing and growing. The eye is equivalent to a camera, the original imaging can be clearly focused, will become blurred due to the increase in the length of the front and rear diameter of the eye, need to increase the number of degrees to form a new focus. After the age of 18, myopia stabilizes slowly as growth and development stabilize. As you can see, the deepening of myopia is related to growth and development. In addition, myopia deepens faster with children reading, writing, watching the computer, etc., is not wearing glasses, its myopia will also increase. Myth 2: Glasses can not be worn? Some parents are reluctant to give their children glasses because they are worried that once the child wears glasses, myopia will become more and more serious and can never be taken off again. Wearing glasses to correct vision can make your child’s vision develop normally, and can prevent amblyopia, or help amblyopia recovery. Myth 3: Computerized optometry is accurate? Many optical stores are “computerized optometry, immediately available” as a means of attracting customers. In fact, the ciliary muscle of the eyes of the optometrist has a near-perceptive adjustment force, so the results of the optometry can easily deviate from the actual refraction of the affected eye. Especially for adolescents, whose ciliary muscle adjustment force is stronger, the deviation from computerized optometry is even greater. In addition, computerized optometry is objective and does not require subjective judgment by the person being examined. Although refractive error is an objective basis, it is also a subjective feeling of the person. Therefore, standardized optometry requires subjective optometry on the basis of objective optometry. The results of computerized optometry can only be used as the initial data and the basis of subjective optometry, but not directly as the reference data for prescription lenses. Myth 4: Wearing glasses will cause eye deformation? Many people feel that wearing glasses will cause eye deformation, so many people insist on not wearing glasses even though their eyes have long been myopic. In fact, the longer the length of the eyeball, the higher the prescription for glasses, which is not related to glasses. In other words, it is the deformation of the eyeball that causes myopia, not the glasses that cause the deformation of the eyeball. Myth 5: You don’t need to do eye exams with glasses? Many people often go to the optician for simple optometry and prescription glasses by themselves after they find that their vision is bad. I don’t know that many diseases can affect vision, such as glaucoma, cataract, macular degeneration whose early performance is vision loss. If you only do the optometry and prescription, but ignore the eye examination, you will easily miss the opportunity of early detection of other diseases. Therefore, medical optometry eye examinations should be done first when vision loss is detected. In the exclusion of organic eye lesions, confirmed vision loss is indeed caused by refractive error, and then medical optometry prescription. Myth 6: Astigmatism can be corrected or not? Some opticians do not correct astigmatism because they do not fit astigmatism or do not have the appropriate astigmatic lenses. And some parents give up to save money for students to correct astigmatism. In fact, astigmatism without correction can easily cause visual fatigue, and as long as there is no discomfort in the trial, all need to be fitted with astigmatism. Young children with high astigmatism may cause amblyopia if not corrected, so it is even more important to have early checkups and prescription glasses. Myth 7: You can see clearly with glasses on? Many people use whether or not they can see clearly as an indicator of how well their glasses are fitted. In fact, seeing clearly is only one of the indicators, and the other two indicators determine whether you can see clearly and comfortably for a long time. For example, for presbyopes, they can see clearly with several degrees, but only the degree that is comfortable and long-lasting for the wearer is the most appropriate. Myth 8: You can adjust your own frame when it is deformed? Because often take down and wear, some parts of the articulation of glasses often loose, some people will adjust themselves. In fact, the adjustment of the frame is very technical, the distance between the mirror eye will affect the effective degree of the lens, so the adjusted distance between the mirror eye needs to be maintained at 12-14 mm, the optical center of the lens should be aligned with the position of the pupil, nasal bracket, mirror legs and nose and ear contact parts to match, no pressure pain, etc.. Therefore, it is best to ask a professional fitter to adjust the frame. Some special lenses (such as gradient multifocal glasses) require regular adjustment of the frame.
