Claim 8:
9. The camera optical lens as described in claim 1, wherein the camera optical lens satisfies:

−2.71≤f8/f≤−0.18;

1.18≤(R15+R16)/(R15−R16)≤4.11; and

0.03≤d15/TTL≤0.10,

where f denotes a focal length of the camera optical lens, f8 denotes a focal length of the eighth lens, R15 denotes a central curvature radius of an object-side surface of the eighth lens, R16 denotes a central curvature radius of an image-side surface of the eighth lens, d15 denotes an on-axis thickness of the eighth lens, and TTL denotes a total optical length from an object-side surface of the first lens to an image plane of the camera optical lens along an optic axis.
