Abstract: Based on the law of refraction of light,An accurate formulate of single-spherical refraction of non-paraxial light ray was established. 引言：非近轴光线经光学系统后不再聚于一点，即产生了球差。

To cause(light rays, for example) to diverge; deflect. 使（如光线）发散；使偏离
Light rays show the path and direction of light traveling in. 光线:表示光的传播路径和方向的带箭头的直线.
Do light rays travel in the same direction after reflection? 光线在反射后会沿着相同的方向传播吗？
Each structure has its own refractive index, and when a light ray crosses an area where the index changes, the light scatters, creating a degree of opaqueness. 每个构造都有各自的折射率，当光线穿越折射率不同的区域时，便会散射而造成某种程度的不透明。
