Why does our eye colour change

Eye colour is something that we develop over time. Newborn babies usually have a blue or blue-grey colour. As babies get older, more pigment is produced, creating a stronger colour. Did you know that it’s not just a baby’s eyes that change colour but also an expectant mothers?

Changes can also occur as our age progresses, which will affect around 10 – 15% of people. This occurs because the pigment of the iris begins to breakdown, lightening the colour of the iris. The darker the iris, the less likely this is to occur to such an extent.

There are several conditions that can change the colour of the eyes, such as Fuchs’ Heterochromic Uveitis. This is an inflammation of the front part of the eye and will usually change the colour in the affected eye.

Another condition called Horner’s Syndrome occurs when the eyelid becomes droopy and the pupil becomes smaller than usual. It is most likely to affect babies, resulting in one eye being lighter than the other.

If you have any questions or would like more information about conditions that could affect changes in your eye colour, talk to your local Specsavers optometrist.
