A lens module includes an optical prism. The optical prism includes a prism body and at least one recess structure. The prism body includes a first surface, a second surface, a third surface and a fourth surface, wherein the first surface and the third surface are opposite, the second surface and the fourth surface are opposite, the first surface is adjacent to the second surface and the fourth surface, and the third surface is adjacent to the second surface and the fourth surface. A light beam enters the prism body through the first surface, undergoes multiple total internal reflections in the prism body, and leaves the prism body through the fourth surface. The recess structure is formed on the prism body, and extended from the surfaces of the prism body to the interior.
