When people view anaglyphs with the use of appropriately colored glasses, each eye becomes able to see a slightly different image. Just like in a red and blue anaglyph, the eye that is covered by the red filter gets to view the red colored parts of the image like as if they are white. On the other hand, the eye that is covered with the blue filter sees the images as black. The brain is just so simply amazing that the brain correlates both images and provides a certain adaption to the different colors.

This way, a regular stereograph image is produced without requiring the viewer to cross eyes just to be able to interpret the differences that are results of varying distances.

About the Filters

A pair of anaglyph 3D glasses usually has two filters of the exact same colors. And, no matter how complicated the anaglyph 3D system may seem initially, the eye only gets to see the point of view that it is supposed to see.

Resurgence of 3D Technology

Today, a lot of manufacturing companies are coming up with their very own rendition of anaglyph 3D glasses. The main reason for this is because 3D technology is booming at present, and this resurgence started right after Avatar was dubbed as the new all-time largest grossing blockbuster, a title that used to be owned by a fellow James Cameron film, Titanic.

Also, uncorrected gel glasses or simple paper glasses cannot actually compensate for the two hundred and fifty nanometer differences that have been readily installed with the red and cyan filtered anaglyph 3D glasses.  With paper 3D glasses, the images that are filtered through the red lens are oftentimes blurry. The reason for this is because upon viewing a computer screen that is relatively close or a printed mage, the focus of the retina differs from the image that can be viewed through the cyan-colored filter. The images that are viewed on the blue lens are actually the ones that dominate the eyes’ abilities to focus.

Features

The anaglyph 3D glasses that are being invented today have been readily installed with fantastically molded acrylic glasses that are of better quality. These new glasses are able to employ a good compensation of the differential diopter power, otherwise known as spherical correction, in order to balance the focus shifting that is associated with the red filter. This balance is actually relative to that of the cyan filer, as it reduces the innate softness as well as the diffraction that is involved with the light filtered through the red lens.

The 3D technology associated with today’s set of anaglyph 3D glasses work naturally well with black and white colored images. However, this does not mean that they will not work with other colors since they have excellent results whenever such glasses are used for conforming images that are relatively anachrome-friendly.

Using Them

Today, the US Geological Survey makes use of thousands up on thousands of these full-color anaglyph 3D glasses, as it depicts geological figures and scenic features wonderfully.
