Claim 1:
2. The camera optical lens according to claim 1 further satisfying following conditions:

−3.48≤(R1+R2)/(R1−R2)≤−0.76; and

0.05≤d1/TTL≤0.18;
where
R1 denotes a curvature radius of an object-side surface of the first lens;
R2 denotes a 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 the object-side surface of the first lens to an image surface of the camera optical lens along an optical axis.
