Camera optical lens

A camera optical lens, comprising:

• seven lenses, being sequentially from an object side to an image side, comprising:
• a first lens having a negative refractive power;
• a second lens having a positive refractive power;
• a third lens having a positive refractive power;
• a fourth lens having a negative refractive power;
• a fifth lens having a refractive power;
• a sixth lens having a positive refractive power;
• and
• a seventh lens having a negative refractive power;
• wherein, a field of view of the camera optical lens in a diagonal direction is denoted as FOV, a refractive index of the second lens is denoted as n2, an abbe number of the third lens is denoted as v3, an abbe number of the fourth lens is denoted as v4, a center curvature radius of an object side surface of the sixth lens is denoted as R11, a center curvature radius of an image side surface of the sixth lens is denoted as R12, an image height of the camera optical lens is denoted as IH, a total optical length of the camera optical lens is denoted as TTL;
• and the camera optical lens satisfies following relationships:
• 155.00°≤FOV;
• 1.70≤n2≤220;
• 2.80≤v3/v4≤4.20;
