Camera optical lens

A camera optical lens, comprising five lenses in total, wherein, the five lenses are, 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 positive refractive power;
• and
• a fifth lens having a negative refractive power;
• wherein, the camera optical lens satisfies the following conditions:
• 0.95≤f1/f≤1.15;
• 5.70≤R7/R8≤31.00;
• 1.05≤d5/d6≤2.00;
• and
• 1.25≤(R9+R10)/(R9−R10)≤5.00;
• where,
• f denotes a focus length of the camera optical lens;
• f1 denotes a focus length of the first lens;
• R7 denotes a central curvature radius of an object side surface of the fourth lens;
• R8 denotes a central curvature radius of an image side surface of the fourth lens;
• R9 denotes a central curvature radius of an object side surface of the fifth lens;
• R10 denotes a central curvature radius of an image side surface of the fifth lens;
• d5 denotes an on-axis thickness of the third lens;
• and
• d6 denotes an on-axis distance from an image side surface of the third lens to the object side surface of the fourth lens.
