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 and a seventh lens element sequentially from an object side to an image side along an optical axis, each of the first, second, third, fourth, fifth, sixth and seventh lens elements having an object-side surface facing toward the object side and allowing imaging rays to pass through and an image-side surface facing toward the image side and allowing the imaging rays to pass through, wherein:
the first lens element has positive refracting power, and a periphery region of the image-side surface of the first lens element is concave;
the third lens element has positive refracting power, and a periphery region of the object-side surface of the third lens element is concave;
the fifth lens element has positive refracting power, and an optical axis region of the image-side surface of the fifth lens element is convex;
the sixth lens element has positive refracting power, and an optical axis region of the object-side surface of the sixth lens element is convex;
an optical axis region of the object-side surface of the seventh lens element is convex;
lens elements of the optical imaging lens are only the seven lens elements describe above; and
an Abbe number of the third lens element is represented by V3, an Abbe number of the seventh lens element is represented by V7, a sum of the thicknesses of all seven lens elements along the optical axis is represented by ALT, a distance from the image-side surface of the second lens element to the object-side surface of the third lens element along the optical axis is represented by G23, a thickness of the third lens element along the optical axis is represented by T3, a distance from the image-side surface of the third lens element to the object-side surface of the fourth lens element along the optical axis is represented by G34, and V3, V7, ALT, G23, T3 and G34 satisfy:
V3+V7≤100.000 and ALT/(G23+T3+G34)≤2.700.
