Claim 3:
4. The camera optical lens as described in claim 1, wherein the camera optical lens further satisfies following conditions:

0.53≤(R3+R4)/(R3−R4)≤2.97; and

0.02≤d3/TTL≤0.08,

where
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.
