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

−3.50≤(R1+R2)/(R1−R2)≤−0.72; and

0.05≤d1/TTL≤0.19,

where
R1 denotes a central curvature radius of an object side surface of the first lens;
R2 denotes a central curvature radius of an image side surface of the first lens;
d1 denotes an on-axis thickness of the first 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.
