When the multi-lens magnifier and case is not in use, the cover 80 can be configured to protect the first lens 30 and the second lens 50 received in the housing 10.

The third lens 90 can be substantially flat and can be received in the window 137 of the top wall 13. In at least one embodiment, the third lens 90 can be a plane mirror.

When in assembly, the second lens 50 can be stacked on the first lens 30 and the first coupling hole 31 can be aligned to the second coupling hole 51. The first operation 33 of the first lens 30 can be received in the sliding slot 53 of the second lens 50. The first lens 30 and the second lens 50 can be put into the receiving chamber 18. The first through hole 131, the first coupling hole, the second coupling hole 51, and the second through hole 133 can be aligned to each other. The sliding slot 53 can be aligned to the first guiding slot 133. The first operation portion 33 can be received in the sliding slot 53 and the first guiding slot 133. The second operation portion 55 can be received in the second guiding slot 135. The pivoting member 20 can be inserted into the first through hole 131, the first coupling hole 31, the second coupling hole 51, and the second through hole 151. Thus, the first lens 30 and the second lens 50 can be rotatably coupled to the housing 10. The side cover 80 can cover the opening 11. The third lens 90 can be mounted on the window 137 of the top wall 13.

FIG. 4 illustrates that the side cover 80 can be moved away from the housing 10 and the first lens 30 can be rotated to expose from the housing 10. Thus, the first lens 30 can be configured to shrink text size. FIG. 5 illustrates that the second lens 50 can be rotated to expose from the housing 10. Thus, the second lens 50 can be configured to enlarge text size.

In at least one embodiment, the third lens 90 and the side cover 80 can be omitted. The first lens 30 can be a convex lens and the second lens 50 can be a concave lens. The first lens 30 or the second lens 50 can be other types of lens, such as a sunglass.
