Abstract

An optical imaging lens includes a first lens element to an eighth lens element, and each lens element has an object-side surface and an image-side surface. An optical axis region of the image-side surface of the first lens element is concave, the third lens element has negative refracting power, and a periphery region of the object-side surface of the third lens element is concave, the sixth lens element has negative refracting power, and an optical axis region of the object-side surface of the sixth lens element is convex, the seventh lens element has positive refracting power, and a periphery region of the object-side surface of the seventh lens element is concave. Lens elements included by the optical imaging lens are only the eight lens elements mentioned above, and the optical imaging lens satisfies the following conditions: |V2−V3|≤5.000, and D12/(G45+G67)≤4.100.
