I think you have your answer from the others, which doesn't help you necessarily. You may want to consider frosting or staining your windows so you can allow light in without people seeing inside. Another option if you have space is to put in some kind of hedge, trellis, sunshade or other attractive feature that obscures the view of your window but still allows you to keep a view.
We live very far from our neighbors so we don't even have blinds, but a few years ago we built a house for my mom. Her front porch is ten feet from my bathroom window where our cats like to sit and watch the birds. My mother doesn't have visitors so it's not a problem now, but when the day comes that we are using it for a vacation rental (hopefully a long time from now) we'll have to come up with a solution. I'm thinking about frosting the window in a diamond pattern so the casual observer won't see in, but the cats can still peek outside.
