Additional information

What is vision

  1. The human vision is a very complex process. Vision is a result of the two eyes working almost simultaneously with large portions of the brain to produce the sensation of vision.
  2. The first step in the process is the stimulation of the light sensitive receptors in the eye. This information of the image is then converted into electrical signals which are transmitted by the optic nerve to the brain where it undergoes a lot of pre-processing before reaching the visual cortices in the cerebrum. It is at the end of this process that we have a sense of vision.
  3. We must remember that the eye is actually an extension of the brain and is only one tool in the entire process of vision.

Useful websites

This website has a lot of information on the structure of the eye, the mechanism of vision and eye problems.

Reference Books

  1. NCERT Textbook Chapter Light
  2. NCERT Textbook Chapter Reflection and Refraction
