The human body has two eyes that help it to see the objects around it with a stereoscopic vision, that is, it is able to describe the dimensions, size and depth of the image with finite precision. However, this precision decreases as the distance between the object and the eye increases. The precision also decreases when a weakness or abnormality occurs in one eye.
Scientists note that the stereoscopic vision of the human eye depends on the distance between the eyes and the 5 cm, allowing each eye to see the objects around the perspective of different than what the second eye, so the brain works to merge the resulting images and obtain a three-dimensional image.
With the production of three-dimensional films, the director uses two cameras to film the scene from all dimensions, and then merge the images with each bite. By viewing such films with three-dimensional glasses allows each eye to receive a particular image, and then the brain merges these images to produce a three-dimensional image.
Now, let’s take a look at how you can make your very own 3D glasses at home.
How to make 3D glasses
To make 3D glasses you must prepare the following tools:
- Cardboard in white or black
- Sharp scalpel
- Plastic reinforced and transparent (colorless)
- Wide red and blue crayon pen
- Transparent adhesive tape
- Colored cellophane paper in blue and in red.
1. Draw the Glasses
Use the pencil, draw the shape of the glasses on a cardboard size of the appropriate size, and then empty the glasses using the scalpel, and empty the place of the lenses in a rectangular and identical size in both directions.
2. Cut Them Out
Using the sharp scalpel, two lenses are cut in a rectangular form of transparent plastic, provided they are a few millimeters larger than the size of the lens vacuum in the glasses, to facilitate gluing.
3. Coloring In
Color one of the two lenses resulting from the previous step by red coloring from one of its sides, and color the second lens with blue in the same way.
4. Adding Lenses
Using the adhesive tape, the lenses are pasted on their inner blanks on the inside of the glasses, provided that the colored side is internally oriented and that the adhesive tape is on the outside of the lens and not on the middle or on the inner sides.
5. Adding Cellophane: Red
Cut the red cellophane paper to a size that corresponds with the size of the red lens and stick it over the colored side of the red lens using the adhesive tape and pasting it on the outside of the lens.
6. Adding Cellophane: Blue
The blue paper is cut to a size identical to the size of the blue lens, pasted in the same way. Your brand new 3D glasses are ready for use.
