The surface of the aspherical lens is “not spherical.” Its curvature is slightly changed in the radial direction, and if you look at a cross-section of the lens, you’ll find some depression in the lens rim. This shape enables light passing through the lens to converge onto one point, thereby producing a sharp, clear image.
