Abstract
(EN)

The present disclosure relates to the field of optical lenses and provides a camera optical lens. The camera optical lens satisfies following conditions: 62.00<R7/f4<70.00; 0.10<R1/R2<0.40; and −0.50<R3/R4<−0.30, where f4 denotes a focal length of the fourth lens; R1 denotes a curvature radius of an object side surface of the first lens; R2 denotes a curvature radius of an image side surface of the first lens; R3 denotes a curvature radius of an object side surface of the second lens; R4 denotes a curvature radius of an image side surface of the second lens; and R7 denotes a curvature radius of an object side surface of the fourth lens.
