3D glasses: 3D glasses adopt the most advanced "time division method" today, which is realized by the synchronous signal between 3D glasses and the display. When the display outputs a left-eye image, the left-eye lens is in a light-transmitting state and the right-eye lens is in a light-transmitting state, while when the display outputs a right-eye image, the right-eye lens is light-transmitting and the left-eye lens is not light-transmitting, so that two glasses can see different game pictures and achieve the purpose of deceiving eyes.

VR glasses: VR head display, virtual reality head display equipment. VR head display is to use head-mounted display equipment to close people's vision and hearing to the outside world and guide users to feel in a virtual environment. Its display principle is that the left and right eye screens display the images of the left and right eyes respectively, and the human eye will have a stereoscopic impression in its mind after obtaining these different information.

3D glasses can only change the scene that users see, but not the user experience. For users, VR glasses have a stronger experience than 3D glasses.

Extended data:

The principle of VR glasses is similar to our eyes. Two lenses are equivalent to eyes, but far less "smart" than human eyes. In addition, VR glasses generally divide the content into two screens, cut them in half, and achieve superimposed imaging through lenses. At this time, the center of the pupil, the center of the lens and the center of the screen (after split screen) are often not in a straight line, which makes the visual effect very poor and leads to many problems such as unclear and deformation.

In an ideal state, the eye pupil center, lens center and screen center (after split screen) should be in a straight line (as shown in the following figure). At this time, it is necessary to adjust the "pupillary distance" of the lens to coincide with the pupillary distance of the human eye, and then adjust the center of the picture with software to ensure 3 points 1 line, so as to obtain the best visual effect. Some domestic devices are adjusted by physics or software, such as Storm Mirror, whose pupil distance needs to be adjusted by the knob above, and SVR Glass needs software to adjust the pupil distance.
