Abstract
Present embodiments provide for an optical imaging lens. The optical imaging lens comprises a first lens element, a second lens element, a third lens element, and a fourth lens element positioned in an order from an object side to an image side. By controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least one inequality, the optical imaging lens may exhibit better optical characteristics and an enlarged field angle, and the total length of the optical imaging lens may be shortened.
