Claim 6:
7. The camera optical lens as described in claim 1, further satisfying following conditions:

−0.16≤(R7+R8)/(R7−R8)≤1.44; and

0.05≤d7/TTL≤0.17,

where
R7 denotes a central curvature radius of an object side surface of the fourth lens;
R8 denotes a central curvature radius of an image side surface of the fourth lens;
d7 denotes an on-axis thickness of the fourth 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.
