Abstract: An optical imaging lens including a front lens element group, a minimum-aperture light-shielding sheet and a rear lens element group sequentially arranged along an optical axis from an object side to an image side is provided. The front lens element group includes a first lens element. The first lens element includes a first surface facing the object side and a second surface facing the image side. The first surface includes an object-side surface allowing imaging rays to pass through and a non-optical effective area. The second surface includes an image-side surface allowing imaging rays to pass through and a non-optical effective area. The optical imaging lens further includes a light-absorbing layer disposed on the non-optical effective area of the second surface and an optical film disposed on a first surface of the minimum-aperture light-shielding sheet. The optical imaging lens satisfies the conditions of 2.200?RLavg/RS0avg and RLavg?3.000%.
