Abstract: the refractive state of human eyes will show dynamic changes with different age States, so it should be checked regularly. For example, teenagers can be checked for half a year. In addition, the lens will affect the visual quality due to aging and surface coating wear. The mirror frame will also be deformed, resulting in correction deviation. Therefore, we should pay attention to regular optometry and glasses. Misunderstanding 1 of
: children under 3 years old do not need to check their eyesight.
high myopia. In addition to the acquired causes, many will have congenital eye diseases and abnormalities. If your baby is less than 3 years old, but has the following conditions, please see a doctor as soon as possible.
(1) it is found that the black pupil area of children shows white and yellowish white reflection;
(2) children have obvious photophobia and tears;
(3) children can’t look at the object in front of them or follow the light to rotate their eyes;
(4) When covering one eye, the child has no response, but when covering the other eye, it will immediately cause the child to be agitated and cry; like to look at things askew, etc.
even if your baby seems to have normal vision, bring the child to professional ophthalmology for a simple general screening for about half a year. Because there may be congenital eye diseases or abnormalities (such as retinopathy of prematurity, retinal tumor, congenital cataract, congenital glaucoma, etc.), it is difficult for parents to observe clues, but ophthalmologists can find and deal with these eye diseases in time to avoid permanent visual damage.
misunderstanding 2: Children’s optometry and mydriasis have side effects.
mydriasis (ciliary muscle paralysis) optometry is one of the important optometry methods to check the refractive state of children’s eyes, but most parents are worried about side effects. Experts explain that mydriatic optometry is to drop special ciliary muscle paralysis eye drops into the eyes to make the ciliary muscles of the eyes completely paralyzed and reach the most relaxed state, and then perform optometry without any damage to the eyes.
If there is no mydriasis, the child before the age of 6 has very strong eye regulation ability, that is, his vision will be “fake” during the examination, and there is no hidden danger. In particular, it is very difficult to judge hyperopia, strabismus and amblyopia. Once missed, the child will miss the key correction period before the age of 6. Misunderstanding 3 of
: astigmatism doesn’t matter and doesn’t need to be corrected. When parents take their children to glasses stores, they often hear that astigmatism doesn’t matter and doesn’t need to be corrected. In fact, this should be treated differently. First, astigmatism can be divided into light, medium and high. About 80% of them are mild astigmatism, about 15% are moderate astigmatism and about 5% are high astigmatism. If astigmatism is mild and asymptomatic, it does not need to be corrected, but if there are symptoms such as visual fatigue, squinting and torticollis, it should be corrected accurately. Medium and high astigmatism usually must be corrected. Misunderstanding 4 of
: you can’t take off your glasses if you wear them, and you can’t wear them if you can. Many parents don’t want to match their children’s myopia with glasses because they are worried that their children can’t take them off once they wear them. So they seek methods such as massage, traditional Chinese medicine acupuncture, therapeutic instrument training, eye exercises, health drugs and so on. In fact, these methods can not reverse or control the occurrence and development of children’s myopia. Because there are genetic factors and a large number of acquired environmental factors in the occurrence and development of myopia, myopia in adolescents and children will still show a deepening trend after wearing glasses, which is not the fault of wearing glasses. Myth 5 of
: it’s good to see clearly with glasses. There is no need to replace
regularly. The refractive state of human eyes will change dynamically with different age states. Therefore, it is necessary to check regularly. For example, teenagers can check for half a year. In addition, the lens will affect the visual quality due to aging and surface coating wear. The mirror frame will also be deformed, resulting in correction deviation. Therefore, we should pay attention to regular optometry and glasses. Misunderstanding 6 of
: if myopia is allowed, it is better to do myopia laser in adulthood.
juvenile myopia is irreversible. If it is not treated, it will lead to high myopia and bring many eye complications. Even if myopia laser correction is done in adulthood, it will be much more difficult. Therefore, myopia should be actively treated and develop good eye habits. Otherwise, it will be inherited and make the next generation more myopic.
myth 7: the more expensive the glasses, the more fashionable the better
a good pair of glasses is not the high price, but whether it is suitable for you. For some exaggerated and fashionable large frame glasses, due to the heavy frame, large and heavy lens diameter, incorrect optical center shift of the lens, unstable wearing position, etc., it is easy to lead to inaccurate optical correction, prism effect and increase of aberration, resulting in visual fatigue and decline of visual quality. In particular, some young people with small face shape, small pupil distance and deep degree are not recommended to choose large frame optical glasses. Misunderstanding 8 of
: wearing glasses will cause eye “protrusion”
many people think that wearing glasses for myopia will cause eye deformation and protrusion, resulting in some people with high myopia who are very taboo to wear glasses with accurate height. In fact, it is myopia that deepens and the axis of the eye grows, which leads to the deformation and prominence of some people’s eyes, rather than wearing glasses. The growth of myopia is due to the prominent deformation of the eyes, while inappropriate glasses with significantly low degrees are just more prone to visual fatigue, which may promote the deepening of myopia.
