The present disclosure relates to a method for making a lens. In step 1, a first light pervious substrate and a second light pervious substrate are provided. The first light pervious substrate includes a first surface and an opposite second surface, and the second light pervious substrate includes a third surface and a fourth surface. In step 2, a first optically active part is formed on the first surface of the first light pervious substrate. In step 3, a second optically active part is formed on the third surface of the second light pervious substrate. In step 4, the fourth surface of the second light pervious substrate is attached to the second surface of the first light pervious substrate in such a manner that the first and the second optically active parts have a common optical axis.
