The brain then translates this into a picture of what we see.In general the eyes of all animals resemble simple cameras in that the lens of the eye forms an inverted image of objects in front of it on the sensitive retina, which corresponds to the film in a camera.Focusing the eye,is done by a flattening or thickening of the lens in the eye. This process is known as accommodation. In the normal eye, accommodation is not needed for seeing distant objects. The lens, when flattened by the suspensory ligament, brings distant objects to focus on the retina. For nearer objects the lens is increasingly rounded by ciliary muscle contraction, which rela
