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

−20.76≤f8/f≤21.17;

−62.90≤(R15+R16)/(R15−R16)≤6.24; and

0.06≤d15/TTL≤0.25,

where
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 the image side surface 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.
