Spherical aberration is a visual effect that occurs when increased refraction of light rays strike a lens or a mirror.In laymans' terms, a spherical aberration is when your eyes see spheres around lights bouncing off reflective or magnifying surfaces, resulting in an imperfection of the produced image.Spherical aberrations can occur from changes in the eye's anatomy or physiology.onnect with local specialist for a.

Spherical Aberration. For lenses made with spherical surfaces, rays which are parallel to the optic axis but at different distances from the optic axis fail to converge to the same point. For a single lens, spherical aberration can be minimized by bending the lens into its best form. For multiple lenses, spherical aberrations can be canceled by overcorrecting some elements. The use of symmetric doublets like the orthoscopic doublet greatly reduces spherical aberration.
