Claim 0:
1. A camera optical lens, with six lenses, comprising from an object side to an image side:
a first lens having a negative refractive power;
a second lens having a positive refractive power;
a third lens having a positive refractive power;
a fourth lens having a negative refractive power,
a fifth lens having a positive refractive power; and
a sixth lens having a negative refractive power;
wherein the camera optical lens satisfies following conditions:

−0.75≤(R1+R2)/(R1−R2)≤0.01;

0.04≤d1/TTL≤0.16

60.00≤v1≤90.00;

60.00≤v3≤90.00; and

1.00≤d10/d11≤5.00;

where
R1 denotes a central curvature radius of an object-side surface of the first lens;
R2 denotes a central curvature radius of an object-side surface of the first lens;
v1 denotes an abbe number of the first lens;
v3 denotes an abbe number of the third lens;
d1 denotes an on-axis thickness of the first lens;
d10 denotes an on-axis distance from the image-side surface of the fifth lens to the object-side surface of the sixth lens;
d11 denotes an on-axis thickness of the sixth lens; and
TTL denotes a total optical length of the camera optical lens.
