3D Glasses with Active Shutter have been exclusively designed to work with 3D Projections to provide the wearer a real feel of 3D entertainment. Love 3D? Then you will love these active shutter 3D glasses that have been designed to work with 3D DLP projectors. The reason for these glasses to have active shutter is that some active shutter 3D systems usually require active shutter 3D glasses to work well. The 3D glasses have a liquid crystal layer in each eye's glass that has the property of becoming dense when voltage is applied, being otherwise transparent. These 3D glasses are controlled by a timing signal that allows the glasses to alternately block one eye, and then the other, in synchronization with the refresh rate of the screen. Feel like you are being carved up by the Texas Chainsaw maniac or actually kissing Jenna Jameson’s extra lips? These 3D glasses will make it possible.
