Why aspheric lenses are better
As aspheric lenses are much more expensive than spheric lenses,someone may feel it worth not that money,however,in fact,aspheric lenses are indeed better than conventional lenses.Conventional lenses have a front surface that is sphrical,that means it has the same curve across its entire surface,much like a baseball.On the contrast,aspheric lenses have a more complex front surface that gradually changes in curvature from the center of the lens out to the edge.That`s the reason why aspheric lenses have better visiual conditions than conventional lenses
