Here, what we are talking about "3D Glasses" is a kind of glasses made of LC Shutter Glasses. They are different from the glasses which are made of polarizer and the anaglyph glasses which are made of red and blue color filter. Generally, they can only work for CRT Display, i.e. CRT Monitor, CRT Projector and TV. We offer many kinds of LC Shutter Glasses. According to different applications, they can be used on education, entertainment, presentation, scientific research, ...etc. All of our Eye3D LC Shutter Glasses are developed as a versatile PC 3D/VR system, especially for those who need to implement stereo 3D images which are formed in "Interlaced", "Page-Flipping" and "Above/Below". For hardware itself, it is a device of VGA card independent. So, it can be widely used on most PC 3D/VR applications.
