Ambient light penetrates the routed blinds causing reflection on your television - nothing is more annoying then trying to watch a television show during the day, and having a horrible light reflection on your screen. Privacy is limited at night; people can see through the routed holes on a traditional mini blind.
The View From Outside During The Day
From outside they do offer privacy due to the fact that the light outside is much brighter than the light inside. As you can see from the picture the person in the room can not be seen. However you can notice the items on the sill due to their close proximity to the blind.
So, can neighbors see through your blinds? It's unlikely that your neighbors will see through your blinds as long as you tilt them up. Blinds usually offer privacy and temperature control. But they may be able to see shadows through blinds if the light is on.
If a window shade allows you to see through them during the daytime, you will be able to see into the room at night. With screen shades you are able to see from the darker side of the shades into the light. During the daytime you will be able to see out but harder to see in.
This means that when it comes to the solid fabric of the blind itself, you cannot see through blackout blinds from outside at night, or during the day for that matter either. Blackout blinds then do provide privacy at night, and won't let either light in or out, nor the sight of things best kept private.
Sheer curtains offer little during the day and almost none at night. The moment the sun goes down and lights come on inside the house, sheer curtains can completely expose you to outsiders. Semi-sheers are less translucent and their weave is denser.
Contra Vision® White 24/7 Concealed Vision™ is a one way window film that works at night. Most one-way vision films can only provide privacy during the daytime. At night the films become see-through if the inside is illuminated and blinds or curtains are needed.
The direction — up or down — to close blind slats is a matter of personal preference, but if you want more privacy, tilt them up, with the rounded side facing out. With window blinds tilted up, passers-by can't see in: The convex side faces the window, creating less space through which to view.
No one will see your silhouette through wooden curtains or blinds. Anyone outside can see your shadow while blocking the source of light, but the shadow will not be a silhouette. It will not even be recognizable as the shape of a human.
Turn your blinds up. This direction is better for improved privacy too, as minimized gaps between the slats don't allow curious passersby to view the inside of the house.
If your neighbor is on your property, and staring through your window, they're breaking two laws. They're trespassing, as no one enters a neighbor's home through their window. And, by peering into your home, they are known as a voyeur, or “Peeping Tom.”
To minimize light leakage and ensure privacy the blind should overlap the window opening by 4" on each side for a total of 8" on entire width. 2) Measure distance from where the top of the blind will be located to the window sill. The blind should overlap the window opening on the top and the bottom by at least 3".
Privacy and Light Control
On the other hand, horizontal blinds are not as good as the vertical option for light control and energy-efficiency. The reason is that when the sun shines downward, the sunlight can easily pass through the cracks between the horizontal slats.
Blinds are still effective even for blocking thermal camera drones from seeing indoors, and the thicker the curtain, the fewer chances there are to see through them.
Sheer and voile roller blinds are window dressings that are made of a see through. These see through blinds have a transparent weave which allows you to see the view outside but to protect you from prying eyes outside.
Looking through a window with binoculars can be problematic. Windows are nowhere near optically perfect. Many of us are looking through double glass windows and the older ones in particular can cause a noticeable loss of resolution due to "mini refractions".
Privacy blinds, or “routeless” blinds, do not have a lift cord that passes through the center of each of the slats. Because they don't have holes allowing this cord to pass through, they give you additional privacy and control the light a little better. You can still lift privacy blinds.
Light and Privacy
Vertical blind slats are thicker than horizontal blinds. This blocks sunlight more effectively providing UV protection and can also keep heat from escaping during the cold seasons. Not only do vertical blind slats help with sunlight, but they also give you the ultimate privacy when completely closed.
Zebra Shades are a very modern alternative to a horizontal blind. Zebra Shades are Roller shades that allow you to transition between sheer and privacy. The blinds can be adjusted so that the 3" zebra stripes line up-offering privacy, light control, and insulation.
Fencing for Privacy
The most simple solution and the start of any garden boundary is to install a fence for the surround. Not only will it protect your property from intruders, but you will also block out your neighbours' view directly from their garden into yours.
If you believe your right to privacy is being violated by your neighbor's security camera, you should contact a lawyer to figure out how to proceed. For the vast majority of cases, however, there is no legal violation. Your neighbor most likely is not invading your privacy with their security cameras.
