maybe next time don't quote something author made up and quote actual study: > One study led by Cassie Ludwig, an ophthalmologist at the Byers Eye Institute at Stanford University, tracked 148 babies born at Lucile Packard Children's Hospital in California, recording their iris colour at birth. Nearly two-thirds of babies were born with brown eyes, and one-fifth with blue. > Two years later, Ludwig and her colleagues found that of the 40 blue-eyed babies in the study, 11 had brown eyes by the age of two, three had hazel, and two had green. Of the 77 brown-eyed newborns, almost all (73) still had brown eyes at the age of two. Most of the children (2/3) in study were born with brown color, pretty much none of these 2/3 changed the color. There was rare group (1/5) born with blue eyes where 40% (2/5) changed color. So TLDR only when you start with blue color* *for nitpickers - there is extremely small chance you will change color, if you start with color other than brown or blue Of course it depends on country, in many European countries blue/grey is very common and brown definitely doesn't amke 2/3 of newborns. But it's truth same as with hair you don't go from dark to light, it's possible only the other way. I was born with completely blonde hair, now I have light brown and from what I see other kids blonde baby is pretty much standard, but seeing blonde adults it's relatively rare.
