Abstract

The present disclosure provides a camera optical lens, which includes, from an object side to an image side in sequence: a first lens having a positive refractive power; a second lens having a positive refractive power; a third lens having a positive refractive power; a fourth lens having a refractive power; where the camera optical lens satisfies following conditions: 10.00≤d5/d6≤25.00; 2.00≤f2/f≤9.00; 3.00≤(R7+R8)/(R7−R8)≤25.00; and −2.00≤f4/f≤10.41. The camera optical lens satisfies a design requirement of a large aperture, ultra-thinness and a wide angle while having good optical functions.
