青少年配镜扩瞳验光的主要目的,是确定其真正的屈光状态。因为大多数青少年,由于长时间看近距离目标,可使睫状肌持续收缩、痉挛,致使晶状体凸度增加,物像落在视网膜前,造成假性近视或者使原来的远视眼呈近视状态。充分散瞳后,睫状肌痉挛状态解除,青少年眼睛到底是近视、远视还是散光,便一目了然。部分家长对散瞳药有恐惧感,担心散瞳对青少年眼睛不利是毫无科学根据的。散瞳后暂时近距离视物不清、畏光等症状,会随药物作用消失逐渐消失,而不会影响青少年学习。 Teenage glasses dilated optometry main purpose is to determine its true refractive status. Because most young people, due to long-term close look at the target, the ciliary muscle can continue to shrink, spasm, resulting in increased lens convexity, like falling in front of the retina, resulting in pseudo-myopia or the original hyperopia was myopia state. Full dilation, the ciliary muscle spasm release, young people in the end is myopic eyes, hyperopia or astigmatism, it is clear at a glance. Some parents have a sense of fear of mydriatic, fear of mydriasis on the eyes of young people is not scientifically based. Mydriasis after the temporary short-sightedness, photophobia and other symptoms, disappear with the disappearance of the role of drugs will disappear, without affecting young people learning.
