Pronunciation[edit]
Noun[edit]
spherical aberration (plural spherical aberrations)
 (optics) A type of lens aberration which causes blurriness, particularly away from the centre of the lens.
 1991, Virendra N. Mahajan, Aberration Theory Made Simple, page 27,
 For p = 1, the values of q giving minimum spherical aberration (q = 0.71) and zero coma (q = 0.8) are approximately equal to each other.
 2002, Michael J. Kidger, Fundamental Optical Design, page 151,
 If the refractive index is low, the minimum spherical aberration is not greatly affected by the fact that the second lens operates in a converging beam, and the spherical aberration is approximately equal to h^{4}K^{3}.

 Conventional spherical intraocular lenses (IOLs) have positive spherical aberration.
