You may have learned in biology class that your eye color is determined by the genes you inherited. (Genes are essentially “sets of recipes” that are provided in our DNA.) Along with that, you were probably taught about dominant and recessive genes. For eyes, the dominant gene for the color brown always won over the recessive gene for blue eyes. Unfortunately, that information isn’t right. In the past decade, scientists have discovered the influence of genes on eye color is a little more complicated.

A number of different factors define a person’s eye color, the most important of which is eight different color-related genes. The genes control how much melanin, or color pigment, exists in the iris of your eyes. For instance, a gene called OCA2 controls almost 75 percent of the blue-brown color spectrum. Other genes can overrule OCA2, but that rarely happens. This can explain why green eyes are a rarity throughout the world.

But consider that more than 80% of a child’s learning happens through vision, and it’s easy to understand how an undiagnosed vision problem could impact learning and performance, grades, self-esteem, and more. That’s why regular eye exams are so important for your child. Sometimes, undetected vision problems are mistaken for a learning disability, such as dyslexia or ADD.

Are Contact Lenses OK for Your Child?
There are many factors to consider when determining whether or not your child is ready for contact lenses. To help you make the right decision, here are three key questions to you need to ask yourself: 

1. Are contact lenses safe?
Physically speaking, contact lenses are safe for children at a younger age than you might realize. In some cases, infants are fitted with contact lenses for conditions that are present at birth. And unlike adults, children are less likely to suffer from dry eyes, which makes them better candidates for wearing contact lenses. 

2. Is my child ready for the responsibility?
The answer to this is obviously subjective. Only you know if your child is ready to take care of his or her contact lenses. Think about how they handle current responsibilities, such as homework and chores. Are they having issues with that? If so, contact lenses might not be in their best interest until they can properly manage these aspects of their life.
