1. An optical imaging lens assembly, comprising, sequentially along an optical axis from an object side to an image side:
a first lens, having a positive refractive power, an object-side surface of the first lens being a concave surface;
a second lens, having a negative refractive power, an image-side surface of the second lens being a convex surface;
a third lens, having a refractive power;
a fourth lens, having a refractive power;
a fifth lens, having a refractive power;
a sixth lens, having a refractive power;
a seventh lens, having a refractive power; and
an eighth lens, having a refractive power;
wherein 1.0<f6/R11<2.0,
wherein f6 is an effective focal length of the sixth lens, and R11 is a radius of curvature of an object-side surface of the sixth lens.
