When you were born, you likely had blue eyes. Melanin is a pigment that gives your eyes, skin, and hair their color. Once your body became exposed to light, it started to produce melanin, which in turn changed the color of your hair, skin, and eyes. However, genetics also factor into skin, eye, and hair color.
For example, if your parents have darker skin and hair, then you likely had those same dark pigments in your skin and hair when you were born. Your eye color, however, probably took a little more time to develop. The longer your eyes were exposed to light, the more melanin pigments your irises produced. But depending on your genetics, your eyes could have turned dark brown. So regardless of how much or little light exposure you have, your genes determine how light or dark your eye color is.
However, several factors can influence your eye color and whether or not it changes to a different pigment. As previously mentioned, exposure to light causes your body to produce more melanin. An untreated eye infection can become severe and possibly lead to blindness. Learn more: Chronic dry eye and contact lenses ». Iris implant surgery was first developed to treat traumatic eye injuries and medical conditions.
These include aniridia, when the entire iris is missing, and coloboma, when part of the iris is missing. During this procedure, the doctor makes a small incision in the cornea and inserts a silicone-based artificial iris, folded to fit into the slit. They then unfold the artificial iris underneath the cornea so that it covers the natural iris. Despite its medical purposes, the procedure has become increasingly popular for cosmetic reasons.
Many people opt to undergo surgery to change their eye color, even though their natural iris functions normally. Research shows that people who have had cosmetic iris implant surgery are more likely to experience complications. Cosmetic iris implant surgery is a relatively new and controversial practice that has yet to be scrutinized fully by medical researchers. There is little to no evidence proving the procedure is effective and safe.
Because of this, people must travel overseas to get this surgery. Another controversial practice to permanently change your eye color from brown to blue includes the use of a low-energy laser. This laser removes pigment from the layer of interlaced tissue in the iris, known as the stroma. Gregg Homer, a scientist who founded the Stroma Medical Corporation in , developed this technique. The short answer: no.
The pigment melanin determines your eye color. Eyes with a lot of melanin will be naturally darker. For the most part, your eye color will stay the same from infancy.
This is because eye color is determined by your genes and the melanin level on your body. As you grow up, the melanin level increases around your pupil, making the eye darker.
Exposure to the sun Melanin production can be activated through solar exposure , meaning that a prolonged time exposure to the sun could make your eyes darker. Emotions Certain emotions can change the size of your pupil and the iris color. When you are happy, angry, or sad, your body releases a hormone that makes your pupil size change.
Clothing and makeup Darker clothes as well as some color makeup on your eyelids, or white eyeliner, are all things that can make your eyes look more vibrant and brighter.
This is just a matter of perception, not reality, but your eyes will definitely pop a bit more than usual! Your diet They say you are what you eat, and for the eyes this is entirely true! The type of diet you keep will influence your eye color. Pigmentary Glaucoma: In this type of glaucoma, the pigment on the back of the iris is disrupted and the loose pigment granules collect on the back of the cornea.
This loose pigment could also collect on the front of the iris, changing the color. During this time, the body produces a darker pigment, known as melanin.
People sometimes notice that their eye color lightens with age. This is natural and should not be a cause for concern. Visibility lenses are tinted to help people see whether their lenses are in their case. The tinting also helps a person to find them if they are accidentally dropped. They do not fully alter the color of the eye, but they can intensify it, making it stand out more.
On these lenses, the iris is colored in fully, allowing a person to change their eye color completely. As with corrective lenses, decorative lenses have certain risks. Failing to clean and care for contact lenses can, in some cases, result in blindness, as well as other eye issues. This means that all contacts, even decorative lenses, sold legally are fitted by an optometrist or ophthalmologist, to reduce the risk of complications.
The organization warns that buying lenses without a prescription increases the risk of developing:. Whether they are tinted or clear, purchase contact lenses from sources that require or offer a prescription and are FDA-approved.
Also, the FDA recommend using the same care toward decorative lenses that a person uses on corrective lenses. This will help to avoid complications. It was developed to repair or replace the iris following illness or trauma.
However, because it can provide a permanent change in eye color, it is becoming popular among people seeking purely cosmetic changes.
