Diffraction

Diffraction can be described as a visual effect where as a result of pupil dilation, some light sources which hit the lens of the eye will appear spread into a larger range of the spectrum, rather than a consolidated wavelength. This results in the experience of rainbows and spectrums of colour embedded across the brighter parts of one's visual field and can be a common experience during day to day life for some people.
