1. An optical imaging lens, sequentially comprising a first lens element, a second lens element, a third lens element, and a fourth lens element along an optical axis from an object side to an image side, wherein each of the first lens element to the fourth 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;
an optical axis region of the object-side surface of the first lens element is convex;
the second lens element is a glass lens element;
the third lens element has negative refracting power; and
an optical axis region of the image-side surface of the fourth lens element is convex; wherein
lens elements of the optical imaging lens are only the four lens elements, and the optical imaging lens further satisfies the following conditional expressions: HFOV/TTL≥15.000 degrees/mm, 0.500≤|RLGmin|/TG and (V1+V2+V3)/V4≤3.000, where HFOV is a half field of view of the optical imaging lens, TTL is a distance from the object-side surface of the first lens element to an image plane on the optical axis, RLGmin is a radius of curvature of a smaller one of absolute values of radius of curvatures of the object side surface and the image side surface of the glass lens element of the optical imaging lens, TG is a thickness of the glass lens element on the optical axis, V1 is an Abbe number of the first lens element, V2 is an Abbe number of the second lens element, V3 is an Abbe number of the third lens element, and V4 is an Abbe number of the fourth lens element.
