Approximately 50% of Caucasian babies are born with blue eyes. However, this can vary depending on the specific ethnicities within the Caucasian population. For example, in some European countries, such as Finland and Estonia, the percentage of babies born with blue eyes is much higher, at around 80-90%.
Additionally, the percentage of babies born with blue eyes can vary within families, as eye color is determined by multiple genes and is not always predictable. Over time, the color of a baby’s eyes may also change as they develop and produce more or less of the pigment that determines eye color.
