Remember back to the last time you experienced the birth of a baby. What was one of the most common questions people asked? Most likely, "WHAT COLOR ARE HIS EYES?,” was right up there.
What makes the color of our eyes appear as they do? What role do genetics play? What if you don’t like your eye color–can you change it? Are there any medications that can change the eye color? Get ready to explore the science behind eye color by starting at the beginning…….
Baby’s eye color can change. A baby can start out with blue eyes, for example, that change to brown as she ages. It’s all dependent on a brown pigment called melanin which develops as a child grows. The more melanin present, the darker the eye color. Brown eyes have the most pigment saturation, green/hazel eyes have less melanin, and blue eyes have the least pigment. The color of eyes is dependent upon genetics. Genetics are complicated, but generally speaking brown trumps blue if there is a brown-eyed parent. This is because darker pigment is the dominant trait in genetics. This isn’t to say that two brown-eyed parents could not have a blue-eyed child……it's just not very common.
So what if you don’t like your eye color? Can you change it? Yes, you can. The most common way is through cosmetic colored contact lenses. It’s possible to change almost any eye color, even changing brown to blue. A special colored dye is injected into the contact lens material, creating magnificent colors. There are also surgical methods for changing iris color but the risks far outweigh the benefits, so it is not recommended. Furthermore, contact lenses are medical devices that alter cellular tissue, so only get contacts by obtaining a prescription from an eyecare practitioner.
Some medications can change eye color. A class of medication called prostaglandins, used to treat glaucoma, has a side effect of darkening the iris color. This same class, in a weaker strength, is used to lengthen eyelashes. Studies have shown that in a certain percentage of patients, light blue and green eyes have turned brown.
So maybe Crystal Gayle was looking into a crystal ball when she sang "Don’t It Make My Brown Eyes Blue," predicting eye color changing medications to come.
Only future science holds the key to permanent eye color change. But in the meantime, genetics, medication, and cosmetic colored contact lenses can enhance and change the color of your eyes.
