Many individuals thought that plastic 3D glasses were all the same. Actually, they are not. They come in three major categories: the anaglyph 3D glasses, the polarized 3D glasses and the active shutter glasses. Each category of glasses is used differently. Their functions vary as well. To know more, here is a detailed description of each category.
Anaglyph 3D glasses
Anaglyph plastic 3D glasses are the most common ones among the other categories. Its 3D effect is achieved when each eye encodes images of different colors. The colors that are often used are cyan and red. Images on Anaglyph 3D are filtered with different colors, one for each eye. When such images are viewed using this type of 3D glasses, each eye will receive the two images intended for them. This will expose a unified stereoscopic image. The brain’s visual cortex will process the image and produce a view of a three-dimensional scene.
Polarized 3D glasses
To create an illusion of a three-dimensional image, this polarized plastic 3D glasses uses polarization. These polarization glasses prohibit the light from reaching into each eye. Two images are projected to place over onto the same screen in order for them to produce a stereoscopic images and film. The lens of each glasses used by the viewer’s contains different polarizing filters. The images seen by each eye are different. This is because the light that enters the eye is restricted. As a result, the eyes are deceived into seeing one 3D image.
Active shutter 3D glasses
Active shutter plastic 3D glasses work by having each eye receive an image intended for them only. So the left eye is presented an image while blocking the view of the right eye and vice versa. This process is rapidly repeated so that the viewers are unable to detect any interruptions. As a result, the fusion of the two images that are seen by each eye produces one single 3D image. To allow the glasses to effectively block each eye and then the other when receiving the images, these glasses are being controlled by a time signal. The signal synchronizes the refresh rate of the screen. This signal is sent via a wired or wireless infrared frequency transmitter. This type of 3D system is commonly used in 3D films.
These three categories of Plastic 3D Glasses are being produced on the market. Holiday specs are known to sell such glasses. They offer the best deals and their prices are affordable. The products they produce are of good quality, hence you do not have to worry about it being a one-time use only. You can use it any time as long as you pack it carefully and place it in an area where it is safe. Plus, they have customized glasses as well and you can choose whatever designs you want.
