The reason you can't see through them is due to the eye's ability to fill in missing information. if the inside of your screen is painted WHITE and it is dark outside, you won't see anything. Tape off a rectangular section of the INSIDE of your security screen and paint it FLAT BLACK. When you answer the door, have the lights INside down low or off, and the light OUTside on, preferably TWO lights, one on each side of the door so the person on the other side is evenly illuminated. With this setup, you'll see through that door as if it wasn't there. Alternatively, you can paint the whole inside surface black or dark gray, and the outside surface white. This will make it difficult for a person outside to look in, while you have a nice view OUT.

To paint the doors two different colors, you have to use a nearly dry roller with a very short nap, or even use a rubber roller with NO nap, so the paint rolls on like a an ink roller. When you paint one side of the metal, you want the paint to be so little that it will not ooze through and run on the other side. Do two coats if necessary rather than trying to cover the surface in one coat. Spray does not work well, because the air current will put black paint on the white side, and vice versa.

You can also cut out a section of your security door and replace it with a sheet of 3/8" Lexan. Pop rivets through a thin aluminum strip, then through the Lexan, then through the metal screen door, then through another thin strip of aluminum will give you an unbreakable window in your security door that is as secure as the metal it replaced. Alternatively, a welder can cut out a window frame and edge it with 3/4" x 3/4" angle iron, allowing you to attach the Lexan directly to it with small screws or rivets.
