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 positive refractive power;
a fourth lens having a negative refractive power;
a fifth lens having a 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:
2.90≤v1/v2≤4.50;
4.00≤f3/f≤10.00;
1.50≤d1/d2≤4.00; and
