Beschreibung
Zusammenfassung:	The invention relates to a lens (100), which comprises a basal body (1) and a plurality of sub lenses (2) which are formed on the basal body (1), wherein each sub lens (2) is connected with adjacent sub lenses (2). The lens is characterized in that the sub lenses (2) are provided with random boundary outlines, light rays produce light spots with the random boundary outlines after passing each sub lens (2), the light spots are at least partially overlapped and/or connected with one another, and uniform light distribution can be obtained. In addition, the invention also relates to a manufacturing method of the lens and a lighting device provided with the lens.
