Point spread function (PSF)
Often used in wavefront diagnostic analysis. A single round spot of light becomes diffused when it passes through an aberrated element such as a human eye. Aberrations cause some of the light to spread beyond the boundaries of the light source, causing the dot of light to appear fuzzy. Analysis of the diffusion of light (spread) helps doctors determine what changes may be made to remove aberrations causing the diffusion.
