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 having a refractive power;
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≤90.00;

−5.00≤f2/f≤−1.50;

1.50≤(R5+R6)/(R5−R6)≤30.00;

−6.00≤R12/R11≤−1.20; and

−20.00≤R13/R14≤−3.00,

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;
R11 denotes a central curvature radius of an object-side surface of the sixth lens;
R12 denotes a central curvature radius of an image-side surface of the sixth lens;
R13 denotes a central curvature radius of an object-side surface of the seventh lens; and
R14 denotes a central curvature radius of an image-side surface of the seventh lens.
