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 from an object side to an image side along an optical axis, each of the first, second, third, fourth, fifth, sixth, seventh and eighth lens element 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:
a periphery region of the image-side surface of the first lens element is concave;
the second lens element has negative refracting power;
the seventh lens element has negative refracting power;
lens elements included by the optical imaging lens are only the eight lens elements described above; and
a thickness of the first lens element along the optical axis is represented by T1, a thickness of the second lens element along the optical axis is represented by T2, a thickness of the third lens element along the optical axis is represented by T3, a thickness of the fourth lens element along the optical axis is represented by T4, a distance from the image-side surface of the first lens element to the object-side surface of the second lens element along the optical axis is represented by G12, 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 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, an abbe number of the first lens element is represented by V1, an abbe number of the second lens element is represented by V2, an abbe number of the third lens element is represented by V3, an abbe number of the fourth lens element is represented by V4, an abbe number of the fifth lens element is represented by V5, and the optical imaging lens satisfies the inequalities:
(T1+T2+T3+T4)/(G12+G23+G34)≥3.800, and V1+V2+V3+V4+V5≥235.000.
