Lens = transparent eye structure that focuses light rays falling on: made up of relatively soft tissue, capable of adjustments the retina that facilitate a process called accommodation, accommodation = curvature of lens adjusts to alter visual focus, focus on close object (cid:224) lens rounds itself, focus on distant objects (cid:224) lens flattens itself.
