Camera optical lens
Provided is a camera optical lens including, sequentially from an object side to an image side: a first lens having a positive refractive power; a second lens having a negative refractive power; and a third lens having a positive refractive power. The camera optical lens satisfies: −0.80≤f1/f≤1.10; 0.30≤d3/d5≤1.00; −20.00≤(R5+R6)/(R5−R6)≤−10.00; 5.00≤R2/f≤50.00; and −10.00≤(R3+R4)/(R3−R4)≤−4.00, where f and f2 denote focal lengths of the camera optical lens and the first lens, respectively; R2, R4 and R6 denote curvature radiuses of image side surfaces of the first, second and third lenses, respectively; R3 and R5 denote curvature radiuses of object side surfaces of the second and third lenses, respectively; d3 denotes an on-axis thickness of the second lens; and d5 denotes an on-axis thickness of the third lens. The camera optical lens can achieve high optical performance while satisfying design requirements for ultra-thin, wide-angle lenses.
