Abstract: our eyes are adaptive. We should also form the habit of wearing glasses. Except that we don’t have to wear glasses when we are near low myopia, we should usually wear them often, so that we can see things effortlessly and benefit our eyes., Myopia refers to a refractive state in which the focus falls in front of the retina after the parallel light is bent through the refractive system of the eye without adjustment. Therefore, myopia can not see the distant target. If the target is gradually moved closer to the eye and the light emitted is scattered to a certain extent, the focus will move backward. When the target moves closer to a certain point in front of the eye. The closer this point is to the eye, the deeper the degree of myopia. When optometrists provide optometry glasses for ametropic patients, they often ask the patients to wear glasses often or under what circumstances. This is based on the specific situation of the patients, not generalize., Does myopia need to wear glasses often?, For young people with medium and low myopia, the main reason is that they can’t see far clearly. Therefore, myopic glasses must often wear glasses when they see far., Because our eyes are adaptive, we should also form the habit of wearing glasses. Except that we don’t have to wear glasses when we are near low myopia, we should usually wear them often, so that we can see things effortlessly and be good for our eyes. If you wear it for a period of time and stop for a period of time, your eyes will not adapt to it, which is easy to make your eyes tired, and the degree of myopia is also easy to deepen. The effective farthest distance (farthest distance) that can be seen clearly for myopia is derived from the formula: F = 1 / d. According to the formula: 1. The furthest effective distance that 00D myopia can see is 1m, 3. 00D myopia was 33 cm. Therefore, 3. Low myopia below 00D can not wear glasses when there is no need to look far, especially when reading and writing for a long time. Because, when low myopia sees near, it rarely uses adjustment force or does not use adjustment force, it can see near objects clearly; Wearing glasses makes you feel uncomfortable. Especially when wearing glasses with high degree, it will induce the development of myopia if you use it to look close., For patients with moderate myopia (- 3.00 ~ – 6.00D), the effective distance to see is between 15 ~ 30cm, which depends on their actual working distance and eye adjustment ability. They decide whether to wear it or not, but they must wear it often when looking far. If the near depth is not as clear as the shallow glasses, it should be equipped with a pair of distance glasses and a pair of near glasses, so as to be suitable for the purpose of being able to see from far and near, and it is also very good for eye health care. For patients with high myopia (above 1.6.00d), because their distant point is only more than ten centimeters or even a few centimeters in front of them, if they do not wear glasses, the whole outside world will become blurred. Therefore, such patients must wear glasses often regardless of distance. But do not match enough brightness, because high myopia can significantly reduce the fundus image, and the affected eye feels uncomfortable. For those who specialize in close work, a pair of shallow proximity mirrors shall be specially equipped., In addition, the diopter of astigmatism is 0. Those with more than 75D (including 0.75D) and self-conscious symptoms should wear glasses. After wearing glasses, they must wear them often regardless of looking close and far. If it is complex astigmatism, myopia can reduce the degree of spherical lens when looking close; The telescope can increase the degree of the spherical mirror. However, the degree of astigmatism can’t be changed whether you look near or far, and you should wear it often.,
