远视眼是自然界的平行光线经过眼的屈光作用后,成像在视网膜后方,不能在视网膜上形成焦点。发生远视眼的原因多由于眼球发育不良,眼球前后轴较正常者短所致。儿童或青少年的轻度远视可以由于调节作用而被代偿。婴幼儿的眼球都属于远视,经过发育才逐渐成为正视眼。 远视眼的治疗可配凸球镜矫正,使平行光线在未进入眼内前,先变成集合光线,使焦点落在视网膜上,形成清晰的物像。轻度远视无症状者则不需配镜;如有眼疲劳症状者应配镜矫正。远视眼配镜前应散瞳验光。 老花眼也称老视眼,随着年龄的增加,约在45岁前后,眼的调节能力逐渐减弱,对近处平行光调节不佳,出现近处视物模糊,
Hyperopia is the natural parallel light through the eye refraction, imaging in the retina behind, not in the retina to form the focus. Occurrence of hyperopia and more due to poor eye growth, ocular axis than normal due to short. Mild hyperopia in children or adolescents can be compensated for by regulatory effects. The eyes of infants and young children belong to hypermetropia, after development has gradually become a face eye. Treatment of hyperopia can be equipped with convex spherical correction, the parallel light before entering the eye, first into a collection of light, so that the focus on the retina, the formation of a clear image. Mild hyperopia asymptomatic who do not need glasses; if symptoms of eye fatigue should be corrected glasses. Presbyopia glasses should be cycloplegic optometry. Presbyopia, also known as presbyopia, with age, around the age of 45, the ability to regulate the gradual diminution of the eye, poor regulation of the parallel light near the emergence of near blurred vision,
