Blue eyes are fairly common. I don't see that they are becoming rare. The eye color is controlled by a set of alleles. If both alleles have the blue gene in them, then the child will have blue eyes. If both alleles have the brown gene, then the eye color will be brown. There are lots of people born with one brown allele and one blue allele. This happens when one parent has blue eyes and the other parent has brown eyes. SO...it is possible for a brown eyed person to possess one blue and one brown allele. This means that a brown eyed person CAN have children with blue eyes. If two brown eyed people were to have a child...and BOTH have one brown allele and one blue allele each. It's very possible that they can have blue eyed children. I once knew a family like this...both parents were brown-eyed...but two of their children only inherited the blue alleles and are blue eyed. Blue eyed people almost 100% of the time only have blue eyed children. This is because to be blue eyed, you only have blue alleles...so a blue eyed couple would only have blue eyed children. But, blue eyed people are not becoming that much of a rarity. My siblings are brown eyed and only had blue eyed children...not a brown eye among the bunch.
