Optics and Vision Science

The eye is an optical system comprising of a cornea and a lens. The crystalline lens of the eye changes its shape to focus light from objects over a great range of distances on the retina. The basic optic function of the eye is to form an image of whatever object being looked at on the retina. The focus length of this lens is adjustable by the muscles attached to it according to the distance of the object so that its image is always formed on the retina in normal situation.
