What are 3D sunglasses?

three -dimensional (3D) sunglasses are an entertainment accessory that uses our binocular vision and is able to create a specially prepared two -dimensional image that appears to be three -dimensional. Binocular vision is a term used to describe an image resulting from two eyes that are used at the same time as humans. When a picture or film was ready for use with 3D sunglasses, it actually consists of two pictures, one designed for each eye. 3D sunglasses force each eye to see only one of the pictures, and the brain combines two, creating the illusion of a three -dimensional image of a "pop -up" from the surface on which the image or film looks. This is a useful ability that creates a wide field of vision, increased depth perception and threadness see weak or distant objects more easily than if the viewer had only one eye. This is the primary driving force of 3D sunglasses that filter different images into each eye. Binocular fusion causes the brain of this pictureY unifies so that while there are two pictures, the viewer perceives only one picture.

There are several different ways of 3D sunglasses insulation of each image for each eye, but the most commonly used are lenses and polarized lenses. The lenses in sunglasses with dual color are usually red and blue or red and green. A picture that has been ready to view sharing these colors. Polarized lenses use light polarization, a process in which light waves are created in only one direction. Each polarized lens detects one light source.

Pictures or movies for viewing 3D sunglasses will have two different images that have been slightly apart, either in colors that correspond to those on two -color 3D glasses or as light patterns designed to view polarized 3D sun glasses. Polarized images are generally povelLive for better than double -color images because they allow full color. Because dual colors of 3D sunglasses use color to separate images, quality and richness of color is significantly reduced.
