1. An optical lens, characterized by comprising:
a first lens having a first surface on an object side and a second surface on an image side, wherein a central area of the first surface protrudes toward the object side to form a protrusion portion, and a top surface of the protrusion portion forms an optical area for imaging, and the first surface further has a first structure area surrounding the protrusion portion, and a side surface of the protrusion portion extending upwards from and perpendicular to the first structure area connects the optical area and the first structure area; and
a second lens component including a second lens barrel and at least one second lens mounted inside the second lens barrel, wherein the at least one second lens and the first lens together form an imagable optical system, and a top of the second lens barrel has an extension portion formed by extending inwardly, and a center part of the extension portion is formed with a light inlet hole of the second lens component, and the topmost second lens of the at least one second lens has a third surface on the object side and a fourth surface on the image side, and the third surface includes an optical area at center, an inner structure area surrounding the optical area, and an outer structure area surrounding the inner structure area, and the outer structure area bears against a bottom surface of the extension portion, and the inner structure area is exposed outside the extension portion;
wherein, the first lens is adhered with the second lens component,
a diameter of a cross section of the protrusion portion is 1.0-2.0 mm,
a height of the protrusion portion is 0.3-1.5 mm, and
a ratio of the diameter of the cross section of the protrusion portion to an aperture of a light inlet hole of the second lens barrel is 0.3-0.6.
