Claim 2:
3. The camera optical lens as described in claim 1, wherein the camera optical lens satisfies:

0.5≤f2/f≤5.80;

−8.28≤(R3+R4)/(R3−R4)≤0.19; and

0.02≤d3/TTL≤0.16,

where f denotes a focal length of the camera optical lens, f2 denotes a focal length of the second lens, R3 denotes a central curvature radius of an object-side surface of the second lens, R4 denotes a central curvature radius of an image-side surface of the second lens, d3 denotes an on-axis thickness of the second 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.
