A childhood belief about eyes

In our family, my mother, sister, and I all have green eyes, while both of my brothers and my father have brown eyes. Naturally I concluded that brown eyes were for boys, and that girls didn't have them. The same was true in reverse for green eyes, which were for girls. Blue eyes, I suppose, could go either way, but nobody in my family has them. Also, since my mother wore glasses and my father did not, I assumed that wearing glasses was a woman thing, not for men.
