Eye Care :

The significance of Vision and Eye care lies behind the fact that, of the total impressions through various senses received by the brain, 75% is through sight. Therefore, extra care and attention to this sense which is vital in our every day activities becomes important. Proper eye care hinges on two things:
  • Basic knowledge about the eye and its function.

  • Regular check ups by a qualified Optometrist / Ophthalmologist and prompt consultation at the first sign of trouble.
The human eye works very much like a camera, but is much quicker to respond to light. It is connected to the brain by the OPTIC NERVE. When the eye views an object, the light reflected from the object passes through the curved, transparent surface in the front called CORNEA. It then travels through a body of fluid known as the AQUEOUS HUMOUR to reach the LENS that converges the rays to pass through a gel called VITREOUS after which an inverted image is formed on the RETINA (a screen at the back of the eye).

This is carried by the OPTIC NERVE to the BRAIN where the image is made 3 Dimensional and erect.

Directly in front of the lens is the IRIS, which is responsible for the colour of the front of eyeball. In the center of this is the PUPIL, a hole which allows light to enter the eye. In bright light, it becomes small, allowing less light to enter the eye and in dim illumination it becomes larger to allow more light to enter the eyeball.
The ability of the eye to focus on close and distant objects is called ACCOMMODATION. This is a function of the CILIARY MUSCLE that holds the lens in place.

Now that you have been briefly introduced to the eyeball and its important structures, we now move on to the problems.
