It allows the lens to go closer to the subject than before and to achieve a larger image scale.

The optical magnifying lenses are diopters for close up photography, which shorten the close focusing distance of the lens. Lenses can be used individually or in combination for maximum effect.(E.g.+1 plus +2 to make a +3 effect or + +2 to make a +6 effect.)
