Abstract
Present embodiments provide for a mobile device and an optical imaging lens thereof. The optical imaging lens comprises an aperture stop and four lens elements positioned sequentially from an object side to an image side. Through 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 shows better optical characteristics and the total length of the optical imaging lens is shortened.
