Abstract An optical imaging lens including at least one lens element and an optical ring element sequentially along an optical axis from an object-side to an image-side is provided. The optical ring element is located on a side facing the image-side of the lens element closest the image-side has an object-side bearing surface facing the object side and in contact with the closest lens element. The object-side bearing surface has an object-side outer periphery and an object-side inner periphery, and the object-side inner periphery is located between the optical axis and the object-side outer periphery. The object-side bearing surface has at least one groove, and the at least one groove extends in the radial direction to the object-side inner periphery.
