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