I remember having blue eyes when I was still a baby, then while growing up, my eye colour changed to grey! I used to think that it was due to magic and something incredible!

when i was a baby,


and when i was 20 years old,


Look how beautiful my grey eyes are! Ain't I pretty now? =)

But, while having my usual eye check-up, I asked my optician why the eye colour of babies will change as they grow older. He said it was because of the exposure to light after birth which triggers the production of melanin in the eyes. By three years of age, the baby's eyes will produce enough melanin to indicate the natural shade of their eyes. But the doctor also said that eye colour change can happen to adults too! This is caused by the exposure to the sun.

Also, pigment in the stroma gives the iris color. Iris color can lighten if the number of pigment granules in the stroma decreases or if the granules produce lighter pigment. The iris can also lose color if the stroma pigment degrades.

The pupil changes size to regulate the amount of light entering the eye. If the iris contains pigment on both the front and back surface, the incident light that reflects off the iris is brown. Sometimes there is little or no pigment on the front surface. The light interacts with the gray iris fibers and the iris stromal cells and reflects as blue. The size and spacing of the fibers and stromal cells determines the "blueness" or "greenness' of the reflected light.

So don't be surprised if your eye colour changes even if you're 50 now! its a natural thing especially for us Caucasians because we have a paler skin!
