摘要
根据光学理论导出焦深与眼的瞳孔大小和眼的等效屈光力之间的关系式，利用模型眼的数据证明了焦深对球面屈光不正的影响，从而阐明了使用针孔镜的原理。
In this paper reported that the formula of relation between the focus depth and the size of human pupil in deduced from optical theory.Using the data of phantom eye the affects of focus depth on spherical ametropia are testified and the principle of use of pin hole is explained.
