Snell’s regulation governs the imaging Qualities of lenses. Light rays passing by way of a lens are bent at both surfaces of your lens. With suitable layout of the curvatures from the surfaces, a variety of concentrating consequences may be recognized. For instance, rays originally diverging from some extent supply of light could be redirected by a lens to converge at some extent in space, forming a concentrated picture. The optics in the human eye is centred around the concentrating Houses on the cornea and the crystalline lens.
