What are passive 3D glasses?

Passive 3D glasses, also known as polarized 3D glasses, are glasses that allow viewers to watch movies or television in 3D without actively changing the picture as it appears through the lenses, as the film progresses. These types of glasses include both paper frames with red and blue plastic lenses that were used in children's magazines, as well as top plastic and metal frames that resemble sunglasses. Red and blue surrounding paper glasses are disposable and remained a specialized form of 3D technology. Passive 3D glasses that come with 3D TVs are repeatedly usable and have lenses that look exactly the same and have no different colors.

Active 3D glasses have circuits that work in accordance with the TV to actively - hence the name - change the way the lenses represent a view of the wearer's eyes. This process continues throughout the film or program, with instructions from television to glasses to change in undetectable additions. Passive glasses have this name,Because there is no activity in lenses or frames. Any activity that allows the wearer to see 3D effects is in the eyes and brain of the wearer. Glasses do nothing.

There are a number of advantages for using passive 3D glasses instead of active 3D glasses have a number of advantages, but not least of them are cheaper and lighter weight. Goggles do not require any energy or moving parts, so the cost of their production is significantly smaller than the cost of active 3D glasses. Passive glasses that cost a lot are those that have bells and whistles such as lenses or special style. The lack of circuits contributes to the light nature of the glasses, which makes it easier to wear for a longer period of time. Instead, some brands of passive glasses look like an ordinary spectacle from the Sci -Fi movie.

One of the disadvantages of these types of glasses is that the video can appear slightly fragmented, as if the lines were running over the screen. Scope, in jaThis happens, differs from brand to brand, so consumers have to test every model when they buy a couple rather than just go by price and style. Another disadvantage is that passive 3D glasses can worsen the image quality due to the optical effects of lenses.
