What Gives Eyes Their Colour?

It's often said that your eyes are the window to your soul, and some even believe that the colour of your eye reflects certain attributes you might possess, but the truth behind it all is much more interesting.

The colour of your eyes depends on how much of the pigment melanin you have in your iris–the coloured part of your eyes. The more pigment you have, the darker your eyes will be. Blue, grey, and green eyes are lighter because they have less melanin in the iris.

Most people in the world will end up with brown eyes. The next most common colours are blue and grey, and green is the rarest colour.

Besides giving our eyes colour, melanin helps protect them from the sun. Light eyes are much more sensitive to the sun's harmful rays than darker eyes because they have less pigment.

Ever-Changing Colours

Newborn babies don't have melanin in their eyes, so they begin life with blue or almost colourless eyes. The melanin gradually increases, and by about three years of age, their eyes will have darkened to their true colour.

Disease, trauma, and aging can lead to changes in eye colour. In fact, our eyes begin changing from the moment we're born.

Superstitions about Eye Colour

Some interesting personality traits attributed to eye colour are:

  • Blue-eyed people have rich imaginations.
  • Those with green eyes have sharp minds.
  • Hazel eyes indicate passionate souls.
  • People with brown eyes are calm but have underlying passion.

No matter your eye colour, it's important to always protect your eyes when outdoors whether you need prescription or not. Make sure you're well equipped with a pair of sunglasses to reflect the sun's harmful rays. Click here to check out the range of sunglasses at your nearest VSP network optometrist.
