Abstract
An optical imaging lens including a first lens element to an eighth lens element arranged in sequence from an object side to an image side along an optical axis is provided. A periphery region of the image-side surface of the first lens element is concave. An optical axis region of the object-side surface of the fourth lens element is convex. The sixth lens element has positive refracting power. An optical axis region of the object-side surface of the seventh lens element is convex, and an optical axis region of the image-side surface of the seventh lens element is concave.
