1. A camera optical lens comprising from an object side to an image side in sequence: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens; wherein the camera optical lens satisfies the following conditions:
0.95≤f/TTL;
−4.00≤f2/f≤−1.90;
1.50≤d10/d11≤3.00; and
0.25≤(R15+R16/(R15−R16)0.90;
where
TTL denotes a total optical length from an object-side surface of the first lens to an image surface of the camera optical lens along an optical axis;
f denotes a focal length of the camera optical lens;
f2 denotes a focal length of the second lens;
d10 denotes on-axis distance from the image-side surface of the fifth lens to the object-side surface of the sixth lens,
d11 denotes an on-axis thickness of the sixth lens,
R15 denotes a central curvature radius of an object-side surface of the eighth lens; and
R16 denotes a central curvature radius of an image-side surface of the eighth lens.
