Changing eyes

At left, my son at ages 5 months (top) and nearly 4 years (bottom), and at right, his little brother at 5 months. Will the baby keep his blue eyes? (Sarah Kelber / May 31, 2012)

I've always been fascinated by eye color, especially as it changes after a baby is born.

As happens with most caucasian babies, both my sons were born with blue eyes, but I haven't expected it to last -- my eyes are blue, but my husband's are brown. My 5-month-old's eyes are still quite blue, albeit with a few streaks around the middle of the iris. I was trying to remember when his big brother’s eyes changed, so I went through some old pictures the other night, and at 5 months, his eyes were already very greenish-brown. (In the photo above, that’s him on the left age 5 months old and nearly 4 years old; baby brother is on the right at 5 months.)

I was thinking maybe my blue-eyed genes might survive in my younger son, then, but the more I looked into it, the more it looks like it’s too soon to tell. Most resources suggest that babies' eyes continue to change up to about 1 year old.


So I guess we’ll have to wait and see.

In case you're wondering why the eyes change, eye color depends on genes and melanin -- melanin responds to light, and since at birth, a baby's eyes haven’t been exposed to light, it takes times for the cells to react to light and have their color be fully expressed.
