Giving the lens an a-spherical shape (such as a paraboloid, hyperboloid or ellipsoid), we can correct this unwanted side effect. That advantage is especially useful in zoom-lenses.

Sep 12, 2024 — The meaning of MAGNIFIER is one that magnifies; especially : a lens or combination of lenses that makes something appear larger.

The production process of the a-spherical lens form is more complicated than that of the regular convex. That is why the prices of aspherical lenses are so much higher.

A normal lens, also called ‘sphere’, has an even convex shape. The disadvantage of this is that an image distortion called spherical aberration can occur: the parallel light rays that pass through the glass do not all end up at exactly the same focal point, resulting in a distorted reproduction.
