The side of a lens is curved. The middle part of some lenses is thicker than the edge. In other lenses, the edge is thicker than the middle part.
透镜的面是曲线型的，有些透镜的中间比边缘厚，有一些透镜的边缘比中间厚。

Some are flared-that is, thicker at the rim than in the center, like a concave lens.
有些呈喇叭形──即边缘较中心厚，类似凹透镜。
8.
It's an easy matter to observe chromatic aberrations, with a thick, simple converging lens.
用一厚的简单会聚透镜很容易观察色差。
