In optics, aberration is a property of optical systems, such as lenses, that causes light to be spread out over some region of space rather than focused to a point. Aberrations cause the image formed by a lens to be blurred or distorted, with the nature of the distortion depending on the type of aberration. Aberration can be defined as a departure of the performance of an optical system from the pr… WebThe IPure is a modified spherical aberration lens, and it has the benefits of both a spherical and a negative aspheric IOL.
