Normal-sighted (Emmetropia)

While we have the most fashionable eyewear, it is our utmost concern to make sure that your overall eye health is well cared for.

In a normal eye rays of light coming from infinity focus at a point on the retina giving us a perfect image. This eye does not require any correction. This condition is called ‘Emmetropia’. Light enters the eye via the cornea and the amount is controlled by the iris, the coloured part of the eye.

The iris contracts and dilates automatically depending on how bright or dim the light is. The crystalline lens then focuses the light on the retina. The retina converts the light into nerve impulses which are communicated to the brain via the optic nerve.

Most vision problems occur when the eye cannot focus the image onto the Retina. Here are a few of the most common problems:

  • Myopia (Near-sightedness)
  • Hyperopia (Farsightedness)
  • Astigmation
  • Presbyopia


When you look at something, three things must happen :

  • The image must be reduced in size to fit onto the Retina.
  • The scattered light must come together that is, it must focus at the surface of the Retina.
  • The image must be curved to match the curve of the Retina.

As shown in the image below, light passes through the cornea and Pupil, is bent (refracted) by the lens, and comes to a point (focus) on the Retina, where the image is formed.
