Camera optical lens

A camera optical lens comprising, from an object side to an image side in sequence:

• a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens;
• wherein the camera optical lens further satisfies the following conditions:
• −10f1/f−3.1;
• 1.7n12.2;
• 1.7n22.2;
• 1f6/f710;
• −10(R1+R2)/(R1−R2)2;
• where
• f:
• the focal length of the camera optical lens;
• f1:
• the focal length of the first lens;
• f6:
• the focal length of the sixth lens;
• f7:
• the focal length of the seventh lens;
• n1:
• the refractive power of the first lens;
• n2:
• the refractive power of the second lens;
• R1:
• the curvature radius of object side surface of the first lens;
• R2:
• the curvature radius of image side surface of the first lens.
