The lens may be a clear, bulging structure within the eye that, at the side of the tissue layer, helps to refract light-weight to be centered on the tissue layer. The lens, by dynamical form, functions to vary the focal length of the attention in order that it will target objects at varied distances, so permitting a pointy real image of the thing of interest to be fashioned on the tissue layer. This adjustment of the lens is thought as accommodation.
