Rays Of Light, Being Reflected From Object, Get

Rays of light, being reflected from object, get in an eye and, passing(taking place) Through a crystalline lens, are focused on a retina of an eye. The RETINA- The analogue of a photosensitive film in a camera is thin The environment covering(lining) an internal surface of an eye. The basic Function of a retina is transformation light - in a nervous impulse which then is transferred(transmitted) in a brain for The subsequent interpretation. The traditional approach to functioning an eye is connected with The theory of German scientist Herman Gelmgoltsa. We shall consider(examine) Work of an eye in a view of its(his) doctrine. According to theory , the adaptation of an eye to - on various distances occurs(happens) by change Curvature of a crystalline lens. Curvature of a crystalline lens varies by - Actions of a special muscle which refers to . Look at figure 2. A normal eye, as shown In figure 2, has the spherical form and in rest it is adapted For sight afar. Thus the rays of light going from removed Objects, are precisely focused on a retina.
