The present disclosure relates to optical lens, and provides a camera optical lens including from an object side to an image side in sequence: a first lens having a positive refractive power, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens; wherein the camera optical lens satisfies the following conditions: 0.95≤f/TTL; −4.00≤f2/f≤−1.90; and 0.25≤(R15+R16)/(R15−R16)≤0.90. The camera optical lens can achieve good optical performance while meeting design requirements for a long focal length and ultra-thinness.
