Camera optical lens

A camera optical lens, comprising, 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 positive refractive power;
• a fourth lens having a negative refractive power;
• a fifth lens having a positive refractive power;
• a sixth lens having a negative refractive power;
• wherein the camera lens satisfies the following conditions:
