There are these inventions called drapes and blinds. Use them. The thing to be cognizant of is more about acoustical privacy. Too many designs back the master straight up to the family room or kitchen, or other public area. You need buffer space between public and private zones. Hearing mommy and daddy exercise is no one’s idea of family entertainment.

My house is a U shape and one side of the U is my master with a window and door leading to the outside. The middle of the house is all glass sliders so yes one can see into the bedroom. In fact one can see into the bedroom also from the other side of the U. Shades work beautifully when privacy is needed.
