How to make 3D glasses?

3D movies have become so popular and interesting,that you want to watch them not only at the cinema, but at home. And for this you need a large screen, so that it's spectacular, and of course, special 3D glasses. Where to get these glasses? You can buy, but you can do it yourself for free or literally for a penny.

For those who do not want to spend their money and want to get points as quickly as possible, we'll talk about how to make 3D glasses. There is nothing complicated in this, and it takes just a few minutes. Let's get started!

What you need for 3D glasses

1. Old unnecessary sunglasses in a plastic frame. If there are none, buy the cheapest. Their main quality is the comfort of wearing.
2. Transparent dense plastic. Need such as, for example, from the badge.
3. Two markers - red and blue.
4. Good scissors.

Instructions - how to make 3D glasses

1. Take the sunglasses and carefully take out of them both lenses.
2. Each lens is applied to the plastic and we cut out the plastic lens from its shape.
3. Take the blue marker and paint it well.plastic lens designed for the right eye. After that, paint the lens for the left eye with a red marker. The main thing is not to confuse anything, otherwise the 3D effect will not work!
4. Gently attach new lenses to the right places.

In front of you - ready self-made 3D glasses! Of course, they are not as steep as those that are distributed in cinemas, but they also give the desired effect. Perhaps, at first it will be inconvenient and unusual for you to look through them. Over time, you will get used to and will be able to not only watch 3D movies in these glasses, but also surf the Internet, which is very interesting in 3D glasses.

Effect from 3D glasses

What is so special about these glasses? After all, they look very simple, the only difference from conventional - the presence of a red and blue lens. Let's try to figure this out.

In the fact that we see images in three dimensions,stereoscopy is to blame. Stereoscopy - any technical means that can record information in three-dimensional form or create depth in the image. A stereo image is a kind of picture or video that uses two images superimposed on each other. So, a well-known movie "Avatar" can be called a stereo image.

Why to watch 3D movies need specialglasses? The fact is that each of the lenses in the 3D glasses is a kind of filter, through which only one of the images enters the eye of the beholder. One lens takes one image, the second - another. The brain works so that the resulting pictures are connected, and the person receives a whole three-dimensional image. To adapt to a true perception of a 3D movie, a person needs only 30 seconds. If you wear these glasses for a long time, then for some time, the perception of colors may be disturbed.

The perception of the film does not change if the person turns his head in every way. And if you watch three-dimensional movies without special glasses, then the image will be fuzzy, slightly vague.

In addition to 3D movies, you can find a large number of 3D images on the Internet. Most often these are macro images or specially converted to a three-dimensional photo system.

In general, watching 3D movies and exploring three-dimensional images is really interesting. And how to achieve a 3D effect, you already know!
