WebPhysically, spherical lenses have a front surface that is spherical, meaning the curve is the same from top to bottom and left to right – like a portion of a sphere. Aspheric lenses, on the other hand, have curves that deviate from the regular spherical curve. 2. Aspherical lenses are much more challenging to manufacture.
