Around the age of 77 years old, Joe Biden's eyes suddenly chnaged from very blue to brown.

I've mentioned this to people and they just shrug their shoulders and say "must be eye cintacts."

So all if his 77 years of life he was happy with bright blue eye and as he's approaching 80 he thinks "brown is better." So he buys brown contacts and never skips a day going back to blue.

Have you ever heard of such a thing before?
