Abstract

The present disclosure relates to the technical field of optical lens and discloses a camera optical lens satisfying following conditions: 65.00≤v1≤95.00; −6.00≤f2/f≤−1.80; and −30.00≤(R5+R6)/(R5−R6)≤−1.50; where v1 denotes an abbe number of the first lens L1; 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; and R6 denotes a central curvature radius of an image-side surface of the third lens. The camera optical lens provided in the present disclosure satisfies design requirements of large aperture, wide angle and ultra-thinness while having good optical functions.
