Using the property of our vision to perceive with each eye individually an image from a certain angle, the scientists created stereo photos and stereo films. That is, for the 3D format, the image is taken in two versions, which are then processed by overlaying one on the other. As a result, with the naked eye you can see a picture with two contours, blurry and with additional contours of either red or blue color around the objects.
In order for the 3D effect to take effect, special glasses are required. In cinemas where a stereo film is shown, at the entrance, polarized devices are necessarily given to each viewer. But, unfortunately, at the end of the session they have to be returned. At home, I also really want to sometimes watch a 3D video or a 3D photo. What to do in this case?
Such a simple device can be bought, or you can make it. And how to make 3D glasses at home, we will tell in this article. In order to enjoy films in this format, lying on the couch in your room, multi-colored glasses, also called anaglyphic, are great.
The advantages of such devices are that they are very cheap, since you can make 3D glasses from ordinary cardboard and two pieces of transparent plastic. True, two more alcohol markers will be needed: one is blue and the other is red. The entire manufacturing process will take only a few minutes. And the master will not need special skills: even a third grader may well cope with this matter.
The second plus should be noted their effectiveness. But the minus is that such glasses physically cannot provide the correct transmission of color stereo images. However, the nervous system copes well with the interpretation of such a picture. A person needs 30 seconds to adapt, and then he will feel comfortable. If for a long period to be in such glasses, then for some time color perception is impaired.
Now on the Internet you can find a huge mass of three-dimensional video. It will be much more pleasant and interesting to watch stereo films with special glasses. So, we offer the reader instructions on how to make 3D glasses yourself.
To work, the master will need:
1. transparent plastic or film;
2. cheap plastic glasses (the frame can be made of cardboard);
3. red alcohol marker;
4. blue alcohol marker;
5. scissors.
The sequence of actions is as follows:
1. If you decide to use old glasses with a plastic frame, then you need to remove the lenses from them; if cardboard glasses are conceived, then two identical parts are cut out, which will play the role of a frame.
2. Cut out from a transparent plastic film a semblance of lenses suitable in shape to the frame.
3. Paint one film in blue and the other in red.
4. The red lens must be inserted on the left side of the glasses, and blue - on the right.
There is another option how to make 3D glasses from the top face of the drive box. First you need to drop a piece of packaging for a few seconds in sufficiently hot water, but not in boiling water. This will make the material plastic, cut with ordinary scissors, but not crumbling.
You need to cut the front part of the glasses, consisting of two ovals, which are connected by a jumper. The edges after cooling the plastic must be cleaned from burrs with sandpaper.
The left side of the monocle is painted over with a red alcohol marker, and the right side with blue. It is very important to observe the rule of arrangement of colors, otherwise there will be no effect. Now the question is how to make 3D glasses, so that they can be used successfully? After all, this option does not provide for the bow to adapt.
A variant of the monocle device is proposed when it is attached with one edge to a long stick. Surely in old films, each of us paid attention to ladies from high society who used monocles in theaters or at balls.
And the easiest option is how to make 3D glasses from ordinary ones with transparent plastic lenses. True, such glasses are more often with diopters. But you can buy with ordinary lenses. Plastic glasses are painted over with markers according to the same scheme as is done in the above methods.
