Abstract
The present disclosure relates to optical lens, and provides a camera optical lens including eight lenses, from an object side to an image side in sequence: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a negative refractive power, a fourth lens, a fifth lens having a positive refractive power, a sixth lens having a negative refractive power, a seventh lens having a positive refractive power, and an eighth lens having a negative refractive power; wherein the camera optical lens satisfies the following conditions: 0.95≤f/TTL; −4.50≤f2/f≤−2.00; and −0.90≤(R13+R14)/(R13−R14)≤−0.25. The camera optical lens can achieve good optical performance while meeting design requirements for a long focal length and ultra-thinness.
