... When light hits the boundary of two mediums, some of the light is reflected and some passes into the new medium. Since the ray of light will be traveling at a different speed, its path is bent. This is called refraction. Bending Light - Index of Refraction, Light, ...

Light Rays
... The optical centre is the centre of a lens. Light rays passing through it do not change direction. The principal axis is the line passing through the optical centre and perpendicular to the lens. Rays parallel to the principal axis converge to or diverge from the focus or focal point of a lens. ...

Optical aberration
.svg?width=300)
An optical aberration is a departure of the performance of an optical system from the predictions of paraxial optics. In an imaging system, it occurs when light from one point of an object does not converge into (or does not diverge from) a single point after transmission through the system. Aberrations occur because the simple paraxial theory is not a completely accurate model of the effect of an optical system on light, rather than due to flaws in the optical elements.Aberration leads to blurring of the image produced by an image-forming optical system. Makers of optical instruments need to correct optical systems to compensate for aberration.The articles on reflection, refraction and caustics discuss the general features of reflected and refracted rays.
