3D glasses are a new phenomenon that allows us to view any object from different angles. 3D Glasses is just an improvement on normal glasses, in fact it may turn out to be the next big thing in the eyewear industry. three-dimensional glass uses polarized glasses to produce the illusion of three dimensional images using just the press of a button. Once the glasses have been installed in your eyes, you will start to see three dimensional objects right in front of you.
The three-d effect is made possible because the light entering your eyes are horizontally polarized. The light entering your eye is also not polarized vertically but rather horizontally. If we were to use ordinary glasses we would only be able to see straight either way but with the help of 3d glasses we will be able to see the object from both the top (horizontal) and bottom (vertical) perspective. Since the light entering our eyes is horizontally polarized, it will seem as though the object is situated in the middle of the lens.
How do 3d glasses work exactly? In order to understand how 3d glasses work, we first need to understand the nature of an image. Every image has two different perspectives depending on whether you are looking at it up, down or sideways. If we take a photograph of a tree below us we will see it from below. If we look at the same photograph from above then we will see it from the other side.
Now since an object that has a halo around it is not visible from our point of view and hence we cannot see it from its perspective, we need to add an additional source of information. This additional source of information comes in the form of lenses. The two unique perspectives of a 3d glasses are the two different prescription glasses that come with it. Prescription glasses are specially designed lenses that are used to correct vision for nearsightedness, farsightedness and astigmatism.
The prescription glasses help to correct these problems by splitting the optical image into two images. The inner image is what we see with our prescription glasses, while the outer image is what we see when looking through the appropriate lenses. To get the best 3d viewing glasses we need to use two different prescription lenses. One lens is for the nearsightedness condition and the other lens is for the farsightedness condition. Each pair of glasses comes with their own focusing system which is very important to consider.
Another way to add depth and dimension to your 3d glasses is by adding a stereo effect to it. The stereoscopic effect is done by displaying one picture as a movie theater screen while combining the images of both lenses onto a single LED panel. For example, if you are using a Focal Reducer with a progressive eye tracking camera then your image will be projected onto a thin layer of foam placed behind the 3d glasses. Using this technology the depth and dimension of your display will be completely realistic and the depth of field effect created will be absolutely perfect.
