Advantage of aspheric lenses is that they can more precisely control the path of light within the lens, sometimes allowing a single aspheric lens to replace the effect that would otherwise require multiple standard lens elements. This results in lenses that are lighter and more compact.Aspheric lenses are widely used in high-end optical systems, including camera lenses, telescopes, contact lenses, rifle sights, and missile guidance systems. They are particularly useful in combating astigmatism and are often used in spectacle lenses.
