    Observers do not need eyeglasses to compensate for near- or far-sightedness, since telescopes can focus out these limitations. Further, other eyeglass characteristics, such as bi-focal, tri-focal, or vari-focal (progressive) designs are severely detrimental when trying to view a large field at infinity.
