Abstract
Present embodiments provide for a mobile device and an optical imaging lens thereof. The optical imaging lens comprises four lens elements positioned sequentially from an object side to an image side. Through controlling the convex or concave shape of the surfaces and/or the refracting power of the lens elements and designing an equation, the optical imaging lens shows better optical characteristics and the total length of the optical imaging lens is shortened.
