yeah, right, only with blue eyes > 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.
