There are two layers to your iris that cause the color of your eyes, and this depends on how much melanin you have in these layers. Most people have at least some in the back layer, and depending on the concentration of melanin in the front, this impacts how light or dark your eye color is. People with more have darker (most likely brown) eyes, while those with less have blue or gray eyes.
Your eye color is one of a kind. That’s right – no one else in the world has the exact same eyes as you. Although brown is the most common eye color—shared by about half the population—no two shades are exactly alike. Though eye color can run in the family, you will still see variations in color between your eyes, your siblings, your parents and your ancestors. This is because a variety of genetic factors determine your eye color, and the color may even change over your lifetime.
So, does your eye color impact your vision or eye health?
Lighter eyes can be more sensitive to the sun and bright lights while brown eyes are more likely to develop cataracts. Other vision issues are often genetic, so even if you did not get your parents’ eye color, you may have inherited their eye conditions.
Medications and medical conditions may also change your eye color. Usually this is not a sign of anything dangerous or negative, but you should notify your doctor so that symptoms and side effects continue to be monitored.
To protect your eyes, make sure you wear sunglasses when you are outside. If you work in construction, manufacturing, or trades where flying dust and debris are common, safety glasses are a daily necessity. They should also be worn during any home maintenance and repair projects. Similarly, if you play contact sports, standard everyday glasses aren't enough—always opt for shatter-proof, sport-specific eye protection.
Speak with your doctor about any changes or concerns regarding your eyes and vision. Getting regular eye exams can help maintain good eye health and overall health.
