This distortion can cause images to appear blurred. By using an aspheric lens, this distortion can be corrected. shoprite from home chester nyWebMost optical lenses have spherical surfaces, because those are most easily fabricated. That surface shape, however, is not ideal for imaging; the outer parts of the lens are then too strongly curved. This results in so-called spherical aberrations which can seriously degrade the image quality. shoprite from home ewing nj
