Abstract
The present disclosure relates to the field of optical lenses, and discloses a camera optical lens. The camera optical lens includes eight lenses, and the eight lenses includes successively from an object side to an image side: a first lens having negative refractive power, a second lens having positive refractive power, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens. An object side surface of the eighth lens is a convex surface at a paraxial position, an image side surface thereof is a concave surface at a paraxial position, and at least one of the first lens to the eighth lens includes a free-form surface. The camera optical lens of the present disclosure has good optical performance while meeting design requirements of a large aperture, ultra-thinness, and a wide angle while.
