How to I add privacy to large picture windows and still see out?

I have this same issue. I have installed mini blinds on all my windows. When open, they let light in during the day but no one can see inside (unless there are lights on inside). If you don't like the look of mini blinds, hanging sheer curtains is another option.

Thank you. But mini blinds still let everyone see inside if they are opened. And sheer curtains let the light in but I still can’t SEE out. Consider me the neighborhood watch guard. I need to be able to watch outside without being in a fish bowl.

Window films may be a good choice, they have the mirrored ones that allow you to see outside, but not inside from the outside.

Wonderful! Where can I find them?

Nancy is has the best solution. Gila Films has all kinds of window films. They make a one way mirror type so you can see out but no one can see in.
