Accommodation  is the process by which the vertebrate eye changes optical power to maintain a clear image or focus on an object as its distance varies.Accommodation acts like a reflex, but can also be consciously controlled. Mammals, birds and reptiles vary the optical power by changing the form of the elastic lens using the ciliary body (in humans up to 15 dioptres). Fish and amphibians vary the power by changing the distance between a rigid lens and the retina with muscles.
