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

65.00≤v1≤95.00;

−6.00≤f2/f≤−1.80;

−30.00≤(R5+R6)/(R5−R6)≤−1.50; and

(R9+R10)/(R9−R10)≥2.00;

where
v1 denotes an abbe number of the first lens;
f denotes a focal length of the camera optical lens;
f2 denotes a focal length of the second 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;
R9 denotes a central curvature radius of an object-side surface of the fifth lens; and
R10 denotes a central curvature radius of an image-side surface of the fifth lens.
