青少年眼屈光不正是常见病、多发病。且发病率目前有上升的趋势,影响着青少年的身心健康。我们在临床中发现,有些青少年在验光配镜时,没有进行散瞳验光,结果配戴眼镜后不合适,甚至给眼睛带来损害。正常人眼在眼球调节静止状态下,来自5米以外的平行光线经过眼的屈光后,焦点恰好落在视网膜上,从而形成清晰的像。如果眼屈光不正,则不能形成清晰的像。临床上屈光不正分为近视、远视及散光三大类。正常人眼都具有调节作用,以适应来自不同距离的光线。调节作用是 Refractive disorders is common in young people, frequently-occurring disease. And the incidence of the current trend of rising, affecting young people’s physical and mental health. We found in the clinic, some adolescents in optometry, there is no mydriasis optometry, the result is not appropriate after wearing glasses, and even bring damage to the eyes. Normal eye in the regulation of the eye at rest, from 5 meters away from the parallel light through the eye refraction, the focus just falls on the retina, resulting in a clear image. If the eye refractive errors, you can not form a clear image. Clinical refractive error is divided into myopia, hyperopia and astigmatism three categories. Normal human eyes have a regulatory role to adapt to light from different distances. Regulatory effect is
