Holographic glasses are specially designed to give points of light a three-dimensional (3-D) prism effect. The term can also be used to describe novelty glasses that have a three-dimensional image embedded in the lens. While originally designed for entertainment purposes, the technology used to create these types of glasses has also been used to develop holographic military goggles.
The main purpose of most holographic glasses is entertainment. The glasses generally have paper or plastic frames and are similar in appearance to 3-D glasses found in many movie theaters. The effects generated by the glasses, though, are more intense and detailed than the types of images generated by 3-D glasses.
Due to the way the lenses in these glasses are designed, normal light displays are viewed as stunning, three-dimensional illusions. For instance, many people enjoy viewing fireworks displays through holographic glasses because of the added vibrant, multidimensional aspects. Similarly, many places that offer seasonal holiday displays may provide guests with holographic glasses to enhance the lights with enchanting prism effects.
Certain novelty glasses with holographic images embedded in the lenses are also called holographic glasses. These products don’t necessarily alter the wearer’s view of objects. Instead, they provide a comical effect for people looking at the person wearing them. For instance, the lenses of the glasses might contain very realistic images of a woman’s eyes, complete with eyelashes and makeup, and when worn by a man, the effect can be quite amusing.
Both types of holographic glasses are available at many toy and novelty stores and are relatively inexpensive. They can also be found online. In addition, quite a few companies and restaurants have offered free holographic glasses in order to entice customers and promote certain products or services.
Aside from entertainment, the technology used to create these types of glasses has been used by the military in order to develop certain eyewear and goggles to be worn by soldiers. The holographic capabilities can enhance the wearer's perception and allow computer-generated images to be projected onto the goggles. These aspects can assist military personnel in assessing field conditions and identifying potential hazards and targets.
Holographic technology continues to evolve. When holographic movies and television shows are available, viewers will likely use holographic glasses in much the same way as they use 3-D glasses. Video and computer games may also utilize holographic technology to enhance gaming, resulting the glasses becoming necessary to fully enjoy the experience.
