While 3D glasses have been around for a few decades, you might be surprised to hear that the majority of advances have only occurred in the last few years. This technology is most commonly used for entertainment for both movies and TV shows, but some advances target more sophisticated markets for professionals. Here are the five most recent innovations for 3D glasses and 3D technology in general.
The majority of passive 3D glasses use red and blue lenses to create the illusion of an image popping from the screen. If you have ever used these glasses, then you know that they often reduce color visibility while also giving many users headaches. There are now several different color combinations that create a similar effect with better results.
Two of the best are treated white lenses and amber with dark blue. The latter is easier to make and allows for nearly full color perception. The former is more expensive and requires specific filters to work, but allows for full color perception because there is only a tiny bit of color in the lenses.
Scientists are working on a screen that projects a 3D image without the use of glasses. While it hasn’t been released to the public yet and will probably first be used for marketing, the results have been fantastic. The effect is achieved by using mirrors that direct the image across the left and right eye to split it up and force the mind to perceive a 3D image.
The problem with most 2D representations of molecules, cells and other microscopic structures is that the designer has to sacrifice some of the true shape or architecture to create a flat image. Anaglyph 3D images allow scientists to see these structures as they are supposed to be, which can help with future advancements.
Active 3D is easily considered the best type of 3D glasses because it reacts to the image on the screen. Unlike passive glasses that remain a specific color, these glasses will keep changing so that you retain full color perception. The problem is that this technology requires batteries and is much heavier. New advancements have allowed these glasses to become much more comfortable, which is leading to widespread acceptance and use.
Many new video games now come with a 3D option that allows players to experience complete engagement with the use of specialized 3D glasses. Some report that the results were mixed initially when this was first done in 2010, but the effect has gotten much better since then. These games often use the white lenses that allow full color perception to ensure that players can easily see everything on the screen.
