Your eyes are like the windows of your body. They are among the five channels that your body uses to communicate with your external world. And just like the other senses, your eyes are integrated with other parts of your body, like your brain. Your eyes are linked to and reliant on your brain to understand and translate what it sees.

Another great analogy for your eyes is that it functions the same way a camera does. Rather, it is said that the camera was fashioned to resemble and function like your eyes. How you see is determined by the transmission of light into your eyes. Like a camera shutter, your eyes adjust either to the increase or decrease of light that passes through them by opening up to allow more light into them or by shutting to prevent excess light from interfering with them.

Different components make up your eye, but the three popular parts we see are the iris, sclera and pupil.


This is the coloured part of your eyes, and it controls how much light gets into your eyes.


This is the white part of your eyes surrounding the iris. It helps maintain the shape of the eye, and it also protects it from injury.


This is the dark dot-like part in the centre of your iris. It changes in size to adjust for the surrounding light. It gets smaller when there is a lot of light and gets bigger when the light is dim or low, just like the aperture does in a camera.

Your eyes are more than just the parts you see. However, it is important to know at least the parts that you can see. If you notice something odd about them, immediately seek professional help from your eye doctor. We are more than able to help you manage any eye problems.
