1. A lens module, comprising:
a first lens having a refractive power;
a second lens having a convex object-side surface;
a third lens having a convex object-side surface;
a fourth lens having a refractive power;
a fifth lens having a refractive power; and
a sixth lens having a refractive power,
wherein the first to sixth lenses are sequentially disposed from an object side to an imaging plane,
wherein a thickness along an optical axis of the third lens is greater than a thickness along an optical axis of the fourth lens, and
wherein 20<V1−V2<45, where V1 is an Abbe number of the first lens and V2 is an Abbe number of the second lens.
