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

0.49≤f3/f≤1.96;

−0.71≤(R5+R6)/(R5−R6)≤−0.20; and

0.04≤d5/TTL≤0.13,

where
f3 denotes a focal length of the third lens;
R5 denotes a central curvature radius of an object side surface of the third lens;
R6 denotes a central curvature radius of an image side surface of the third lens;
d5 denotes an on-axis thickness of the third 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.
