How to choose myopia glasses.如何选择近视眼镜
When buying glasses, to choose a regular professional mirror point, and to consider the following points to buy the right glasses for themselves.
购买眼镜的时候，要选择正规专业的配镜点，并且要考虑以下几点去购买合适自己的眼镜。
(1) The light is to be accurate.
验光要准确。
The photorescopy is the main basis for the mirror. The accuracy of the light examination is directly related to the success rate of the matching glasses. The first degree of optometum should be accurate, and the difference between the upper and lower should not exceed 12.5 degrees of the prescription for the mirror; Secondly, the astration axis should be accurate, and the general axial difference should be limited to positive and negative l 1 3 degrees; Again, the pitch should be accurate, requiring that the pitch be equal to the lens optical heart distance. If the photography does not pay attention to the above-mentioned clearance, the glasses made will appear blurred visual imaging, long-term visual fatigue, dizziness, nausea, and even the appearance of adverse reactions such as resention. Optomet testing is best to go to a professional ophthalmology hospital, children's optometum or the first time with glasses, must use scattered light, so as to be accurate.
验光是配镜的主要依据。验光的准确与否，与配制成的眼镜成功率有直接关系。验光首先度数要准确，其上下差距不应超过配镜处方的12.5度;其次散光轴向要准确，一般轴向差异应限制在正负l一3度之间;再次瞳距要准确，要求瞳距要等于镜片光心距。如果验光不注意上述的把关，配制成的眼镜片会出现视物成像模糊、久视疲劳、头晕、恶心，甚至出现复视等不良反映。验光最好要到专业的眼科医院去，儿童验光或者第一次配眼镜，一定要用散瞳验光，这样才准确。
(2)Mirror selection.
配镜选择。
After the examination, you will take a good photo x-ray to the eyeglass shop with glasses. Note that the eyeglass shop has professional qualifications. In addition, the sophisticated shop will also measure the nose height, nose width, eye and ear distance, frame forward inclination, these are also indicators of whether the glasses wear comfortable. After wearing, it is recommended to try on, try on a longer time, in order to determine whether the glasses are suitable.
验好以后就要带好验光单去眼镜店配眼镜了。注意眼镜店具有专业的资质。另外，考究的店还会测鼻高、鼻宽，眼耳的距离、镜框的前倾角，这些也是眼镜戴起来是否舒适的指标。配好之后建议试戴，试戴时间要长一些，这样才能确定眼镜是否合适。
(3) Mirror frame selection.
镜架选择。
The choice of frame is not only beautiful and good-looking, but also has a great relationship to whether the worn-in glasses can be worn correctly. Therefore, when selecting the frame, pay special attention to the pupil distance and the optical center of the spectacle lens should be placed in a suitable position, and should also match the face shape, so that the matching glasses are not only beautiful and generous, wear it will feel comfortable. How to choose the frame? After all, glasses are worn on the face, there is decorative effect, so still want to see whether it is suitable for their own face shape, in addition to light weight, the size of the frame to be suitable, it is best to measure the pitch, otherwise easy to produce squint and diagonal situation.
镜架的选用不单是美观好看，而且对磨成的眼镜能否正确配戴关系很大。因此配镜选镜架时要特别注意，把瞳孔距离与眼镜片的光学中心要摆在相适应的位置上，并且还应与脸型相匹配，这样配成的眼镜不但美观大方，戴起来会感到舒服。怎么选择镜架呢?眼镜毕竟是戴在脸上的，有装饰作用，所以还是要看是否适合自己的脸型，另外重量要轻、镜架大小要适宜，最好测量一下瞳距，否则容易产生斜视和对视的情况。
(4)New mirror adaptation.
新配镜适应。
Every time with new glasses, just put on when there will always be some dizziness, although the shop always said that this is normal, but in fact glasses must wear comfortable to be good, put on can not have obvious dizziness or visual deformation. Don't let the eyes fit the glasses, be sure to make the glasses fit our eyes.
每次配新眼镜，刚戴上的时候总会有些头晕，虽然店家总是说这是正常的，但其实眼镜一定要佩戴舒服才算好，戴上后不能有明显的头晕或视物变形。不能让眼睛适合眼镜，一定要让眼镜来适合我们的眼睛。
Correction of myopia.近视矫正
The corrective methods of myopia are divided into three main categories:
近视的矫正方法主要分为三大类：
(1) The first category is to wear frame glasses, once found that the child appears true myopia should be timely to give your child frame glasses to correct vision. Frame glasses lenses are divided into a variety of types, a variety of functional lenses have their own advantages. The rate of myopia development can be controlled to some extent.
第一类是佩戴框架眼镜，一旦发现孩子出现真性近视就应该及时给孩子验配框架眼镜来矫正视力。框架眼镜的镜片分为多种类型，各种功能镜片有自己的优点。可以从一定程度上控制近视发展的速度。
(2) The second corrective method is to wear corneal plastic mirror, some children have myopia growth too fast or not suitable for wearing frame glasses, parents may consider wearing corneal plastic mirror for their children to control the development rate of myopia. At present, the most effective way to control the development rate of myopia clinically is to wear corneal plastic mirror.
第二种矫正方法为佩戴角膜塑形镜，某些孩子出现近视度数增长过快的情况或者不适合佩戴框架眼镜的情况，家长可以考虑给孩子配戴角膜塑形镜来控制近视发展速度。目前，在临床上控制近视发展速度最有效的方法即为佩戴角膜塑形镜。
(3) The third method is surgical correction of myopia, but it is not suitable for minor period. You usually need to be at least18 years old before you think about it. Now the technology is also very advanced, has reached the stage of all-flying second laser surgery, in fact, the principle is to cut on the cornea or make a lens, so that parallel light into the eye after the focus falls on the retina, so you can see the distant things clearly.
第三种方法为手术矫正近视，但是手术矫正近视这种方法不适合在未成年时期进行。一般都需要年满，18周岁之后再考虑。现在技术也非常的先进，已经到了全飞秒激光手术的阶段，其实这个原理就是在角膜上进行切削或者制作一个透镜，使平行光线进入眼睛后焦点落于视网膜上，于是就能看清楚远处的东西。
