Understanding Changing Eye Color

eye colorIf you are a new parent and are wondering if your baby’s eyes are going to change color anytime soon, then you are right in thinking so. In fact, did you know that most babies are born with blue eyes and they can change up until they are around three years old? And so although you may think that your baby’s eyes are going to stay that striking blue forever, you are likely wrong. Read on to learn more about changing eye color.

How Eye Color Develops
Most babies are born with blue eyes because the iris of their eye lacks melanin, a pigment that colors the eye as a baby ages. Over time, your baby’s eyes will develop more melanin which could keep their eyes blue or change them to green or even hazel. But if you and your spouse both have brown eyes and your baby has blue eyes, are they bound to get your brown eyes as they age?

Is It Genetic?
In order to fully understand the correlation between eye color and genetics, you need to be aware of the fact that every parent has two sets of chromosomes that they may, or may not, pass onto their offspring. So, although brown is typically viewed as a more dominant gene, it is not always guaranteed that if you have brown eyes, your baby will have brown eyes too. However, it’s fairly safe to say that darker colored eyes beat out lighter colored eyes most of the time. For instance brown beats out green, and green beats out blue.

When Will They Change Colors?
Unfortunately there is no exact science in determining exactly at what age your child’s eyes will change color. However, it is fairly safe to assume that by the time your child reaches the age of 3, their eye color will stay the same for the rest of their life. If you start to notice a streak of a darker looking pigment in your child’s eye, then this is usually an indication that they are developing melanin and that their eyes will in fact change color in the near future.
