A dark ring around the iris of the eye is called a limbal ring. Limbal rings can vary in darkness and thickness and are more pronounced in some individuals than in others. In general, having a limbal ring is considered a normal variation and is not a cause for concern. In fact, a dark and well-defined limbal ring is often considered a sign of attractiveness, as it can enhance the appearance of the eyes and make them appear brighter and more youthful.

However, if you notice any sudden changes or abnormalities in the appearance of your limbal ring or any other part of your eye, it's always a good idea to consult an eye doctor to rule out any underlying medical conditions or eye diseases.

So, in summary, yes it is normal to have a dark ring around the iris of your eye.
