Has your child’s eyeglasses been dilated? Did you choose the best lenses for your child’s glasses? Has your child’s poor vision been examined by an eye specialist? Have you ever given your child contact lenses? These questions may seem simple, but not every parent pays much attention to them. We interviewed many children and parents with visual impairment and found it necessary to clarify some of the misconceptions about children’s eyeglasses. Nanjing Aier Eye Hospital experts believe that the “glasses family” should avoid some of the concept of misunderstanding, to protect the child’s eyesight must start from the details. Misconception 1: “Children can be equipped with glasses without pupil dilation” The holiday season, busy parents, many parents seize the time to arrange a variety of classes for their children, but the child’s eyesight is not good, glasses need to be dispersed in the hospital to check the pupils, due to the pupil dilation of the child can not participate in a variety of classes, so some parents take the initiative! The first thing you need to do is to choose a computerized optometrist for your child. This is very wrong, clinically low children must be dilated pupil optometry, so as to reflect the real visual acuity of the child’s eyes, not through the dilated pupil optometry only rely on the results of the computer monitoring glasses will cause a lot of harm to the child’s eyes. Myth 2: “Expensive eyeglasses must be the most suitable for children”. At present, there are many varieties of frames and lenses on the market, and the prices vary greatly. Many parents in the selection of lenses for children, the pursuit of expensive, that only expensive glasses is the best, the most expensive glasses are suitable for the development of children’s eyes. The main prerequisite for students to choose glasses should be suitable for themselves, do not just pursue fashion to pick rimless frames or perforated frames. The first thing to consider when choosing lenses for your child is resin hardened eyeglass lenses, glass lenses are fragile and can easily cause damage to your child’s eyes. Resin lenses mainly require accurate astigmatism axis position, the optical degree must be accurate, there should be no scratches on the lens, there should be no air bubbles and impurities, the degree of preparation of the child’s eyeglasses lenses must comply with the quality testing standards issued by the state. The error of the refractive error should be within the requirements of the national standard. Myth 3: ” For the sake of the beauty of the child’s eyes, you can give the child to wear contact lenses” Some parents think that once the child puts on the frames, the child’s eyeballs will protrude, affecting the beauty of the child’s eyes, and therefore give the child to wear contact lenses. This is a cliché, and he advises that when choosing to wear contact lenses, one should consider whether his or her child specifically needs them. There is no need for students to wear contact lenses because their safety requires a high level of use, and unscientific methods of use can cause serious damage to the cornea. Especially the younger children can not wear contact lenses, due to the will not be very good care, the domestic wear contact lenses lead to severe keratitis cases are not uncommon. Myth 4: “Children’s glasses must emphasize the same degree in both eyes” Many parents blindly pursue the same degree in both eyes in order to achieve beautiful corrective effect. In fact, this is not true. The refractive error of both eyes of each child is not the same, clinically we call the refractive error of both eyes of the child more than 100 degrees – 150 degrees refractive error, of which more than 100 degrees of astigmatism and more than 150 degrees of spherical lens of the refractive error, may cause the child’s two eyes image is not the same, resulting in a decline in the quality of vision, the hospital’s optometrists for the child’s optometry, pediatric ophthalmologists must also be based on the child’s eyes. The pediatric ophthalmologist will also try the glasses according to the specific condition of the child’s eyes, and the degree of tolerance of refractive error in both eyes is different for each child. Based on years of clinical experience, experts believe that children with refractive error should be equipped with glasses as early as possible. Experts emphasize that the difference between the two eyes of a child can be up to 100-2000 degrees, the younger the child, the better the degree of tolerance, the greater the degree of tolerance. Therefore, it is wrong for parents to blindly pursue the same prescription for both eyes, which is not conducive to the visual development of both eyes of the child. Myth 5: “Children can only with glasses without eye examination” Many parents found that the child’s vision is not good, often in order to save trouble, take the child to the street optical store with a computerized optometry, the child hastily with glasses. Some parents think that their children’s glasses are just glasses and do not need to go to the hospital to check their eyes. There are many causes of vision loss in students, and sometimes it is not necessarily caused by myopia and myopic astigmatism. Some fundus lesions also show up as vision loss.
