Camera optical lens comprising seven lenses of ++−−+−− or ++−−−+− refractive powers
The present disclosure discloses a camera optical lens including a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The camera optical lens further satisfies following conditions: 1.51≤f1/f≤2.50; 1.70≤n5≤2.20; 0.00≤f3/f4≤2.00; 3.00≤(R13+R14)/(R13−R14)≤10.00; and 1.70≤n6≤2.20; where f denotes focal length of the optical camera lens; f1 denotes focal length of the first lens; f3 denotes focal length of the third lens; f4 denotes focal length of the fourth lens; n5 denotes refractive index of the fifth lens; n6 denotes refractive index of the sixth lens; R13 denotes curvature radius of an object side surface of the seventh lens; and R14 denotes curvature radius of an image side surface of the seventh lens.
