An article by Douglas Belkin in the Boston Globe goes further into research studies on the subject, and also discusses one other thing I found interesting. Eugenicists in the 1930s were already noting the decline of blue-eyed people, and used it "as a rallying cry to support immigration restrictions." They even went so far as to create maps of the country, highlighting the regions with the largest and smallest percentages of blue-eyed individuals.
Blue eyes are a recessive trait, but our family must have a particularly hardy variation. Despite my father's beautiful brown eyes, my siblings and I all have blue or green eyes, and my three children all have blue eyes as well. Guess we're doing our part to make sure blue eyes don't disappear forever...

It’s a wise child that knows his father…….
