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 positive refractive power; and
a fifth lens having a negative refractive power,
wherein the camera optical lens satisfies following conditions:
0.90≤f1/f≤1.30;
-5.00≤f3/f≤−2.50;
10.00≤d1/d2≤25.00; and
0≤(R7+R8)/(R7−R8)≤0.90,
where f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, f3 denotes a focal length of the third lens, R7 denotes a curvature radius of an object side surface of the fourth lens, R8 denotes a curvature radius of an image side surface of the fourth lens, d1 denotes an on-axis thickness of the first lens, and d2 denotes an on-axis distance from an image side surface of the first lens to an object side surface of the second lens.
