Abstract
An optical imaging lens, including a first lens element and a second lens element arranged in sequence from an object side to an image side along an optical axis. Each of the first lens element and the second lens element includes 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 image-side surface of the second lens element is concave, and a periphery region of the image-side surface of the second lens element is convex.
