An optical imaging lens, which may comprise, in sequence from the object side to the image side along the optical axis, a first lens (E1), a second lens (E2), a third lens (E3) and a fourth lens (E4) which have optical power; the first lens (E1) may have positive optical power, an object side surface (S1) thereof may be a convex surface, and an image side surface (S2) thereof may be a concave surface; the second lens may have negative optical power; the third lens (E3) may have negative optical power, an object side surface (S5) thereof may be a convex surface, and the image side surface (S6) thereof may be a concave surface; the fourth lens (E4) may have positive optical power or negative optical power; an air interval T23 of the second lens and the third lens on the optical axis and the distance TTL from the object side surface of the first lens to an imaging surface of the optical image lens on the optical axis may meet: 0.5<(T23/TTL)*10≤1.0.
