Diverging Lens or Concave Lens
Human Eye
Human Eye: Its lens is a transparent structure made of proteins. The focussed image falls on a screen behind the lens, called the retina. Retina consists of two types of photoreceptor cells:
I. Rod cells: They are responsible for black and white vision, night vision and peripheral vision. They are more in number.
II. Cone cells: They are responsible for colour vision. They are less in number
The retina sends electrical signals to the brain through the optic nerve so that we perceive objects. The cornea is a transparent spherical structure that refracts light into the eye. The iris is a dark muscular assembly that controls the size of the pupil, the opening that regulates the amount of the light entering the eye. When the light is very bright, the pupil becomes very small, while in a dim light it opens. up fully through the relaxing of the iris. The light through the cornea and pupil falls on the lens, which focuses it on the retinal screen. The retina has an enormous number of light-sensitive cells. These get activated upon illumination and generate electrical signals that are sent to the brain through the set nerves. The brain interprets these signals as the sense of light.
