这是面凸面镜。
As a result, aberration of convex hyperboloid mirror is well corrected, so it is convenient for testing.
从设计的结果可以看出，凸双曲面反射镜的像差已经得到了很好的校正，从而使检验变得更加方便。
Easy View does not block rear visibility and does not need to be positioned directly over a child. The shallow convex shape offers the largest, clearest reflection of any back seat mirror.
后座反射镜，视野宽阔，不会阻碍后视镜的能见度，也不需将孩子直接对着后视镜，凸透镜最大最清晰地映射出所有后座镜子的情况。
