1. An optical imaging lens, comprising a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element, and an eighth lens element sequentially along an optical axis from an object side to an image side, wherein each of the first lens element to the eighth lens element comprises an object-side surface facing the object side and allowing imaging rays to pass through and an image-side surface facing the image side and allowing the imaging rays to pass through;
the second lens element has negative refracting power;
a periphery region of the object-side surface of the third lens element is concave;
an optical axis region of the image-side surface of the fourth lens element is concave;
an optical axis region of the object-side surface of the fifth lens element is concave;
the seventh lens element has positive refracting power, wherein
lens elements of the optical imaging lens are only the eight lens elements, and the optical imaging lens satisfies a condition of D52t81/D41t52≥3.000 and a condition of V3+V4+V5≤125.000, where D52t81 is a distance from the image-side surface of the fifth lens element to the object-side surface of the eighth lens element on the optical axis, D41t52 is a distance from the object-side surface of the fourth lens element to the image-side surface of the fifth lens element on the optical axis, V3 is an Abbe number of the third lens element, V4 is an Abbe number of the fourth lens element, and V5 is an Abbe number of the fifth lens element.
