Naturally, eye colour change is because of the level of melanin in the body. Ever notice how a baby’s eyes sparkle, as does its skin?
Well, the ever-enlarging database of science has added to its collection the reason why this glow soon fades as the baby grows up.
The low level of melanin in a baby is the cause; consequently, when a child starts growing, chances are the child will be exposed to sunlight, which enlarges the melanin levels in the body.
Thus changing the colour of the body parts, including the eyes. With this in mind, it becomes easy to understand that the longer your eyes are exposed to light, the more melanin pigments your irises produced.
However, it is important to note that genetics is also a major factor in influencing the skin, eye, and hair color.
Here are the potential causes of changes in eye colour:
1. Sun exposure
Exposure to light can make your body produce more melanin, which will lead to a change in your eye color. Sunlight can reveal colours that were already in your eyes, and because natural sunlight is mostly brighter than artificial lights, being exposed to it might let you see colors in your irises that you never recognized before.
2. Changes in pupil size
As unbelievable as it sounds, your pupils’ size can also affect the color of your eyes. When your pupils shrink or dilate, the color actually changes. For instance, if your pupils widen, your irises will not be totally exposed, and the remaining irises will appear darker.
3. Heterochromia
It is possible that you have developed heterochromia, a rare condition when your eyes changes colour significantly. Heterochromia is a condition where every iris has a different color. And if you did not know, this condition can be gotten from Eye surgery, Eye bleeding, Eye swelling and Eye injury.
4. Tumors in the iris
Research has shown that some of these tumors can have damaging effects on your ocular and general health. If you suspect a drastic change in your eye color as an adult, you should see an ophthalmologist or optometrist to find out exactly what is wrong.
5. Glaucoma
This is an eye condition that damages the optic nerve, the health of which is vital for good vision.
