定义
一种屈光误差,由于眼球前后距离过短,平行于视轴进入眼睛的光线在视网膜后聚焦。它也被称为远视,因为近点比在调适幅度相同的情况下的远点更远。
A refractive error in which rays of light entering the eye parallel to the optic axis are brought to a focus behind the retina, as a result of the eyeball being too short from front to back. It is also called farsightedness because the near point is more distant than it is in emmetropia with an equal amplitude of accommodation.
