Abstract:
Provided are an optical lens (110) and a lens module (10), the optical lens (110) comprising an optical part (1) used for imaging and a supporting abutting part (2) arranged around the optical part, the support part (2) comprises an object-side supporting abutting face (21) adjacent to the object side and an image-side supporting abutting face (22) arranged opposite to the object-side supporting abutting face (21), and the object-side supporting abutting face (21) and/or the image-side supporting abutting face (22) are provided with at least two recesses (24) distributed sequentially in the radial direction of the optical lens (110); the object-side supporting abutting face (21) comprises an object-side abutting face (211) connected to the optical part (1) the image-side supporting abutting face (22) comprises an image-side abutting face (221) connected to the optical part (1), two adjacent recesses (24) are spaced apart to form an end face, the object-side abutting face (211) on the same side as the end face is flush with the end face, and the image-side abutting face (221) on the same side as the end face is flush with the end face. Thus the optical lens (110) can reduce stray light caused by a long supporting abutting part without affecting the flatness of the object-side supporting abutting face (21) and/or the image-side supporting abutting face (22), improving the imaging quality of the optical lens (110).
