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

−4.12≤(R1+R2)/(R1−R2)≤−0.33; and

0.04≤d1/TTL≤0.15,

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 the object side surface of the first lens to an image plane of the camera optical lens along an optic axis.
