3D glasses

Abstract

The invention discloses 3D glasses which are flexible in adjustment and strong in adaptability. With the 3D glasses, the audience can clearly watch a movie. The 3D glasses can overcome the defects that by wearing 3D glasses in the prior art, the audience can not clearly watch movies due to an improper interpupillary distance, an improper watching distance and other factors. The 3D glasses comprise glass feet and a nasal support. The two ends of the nasal support are provided with a pair of polarized lens frames which are connected with the glass feet. Polarized lenses are arranged in the polarized lens frames. Multiple pairs of auxiliary lens frames are arranged on the polarized lens frames. Adjusting lenses which are connected with the auxiliary lens frames in an inserted mode are arranged in the auxiliary lens frames. The adjusting lenses are convex lenses. The nasal frame comprises a left half frame and a right half frame, wherein the left half frame and the right half frame can move relative to each other. The 3D glasses are applicable to occasions where conventional 3D glasses are used before and have the advantages that the interpupillary distance is adjustable, the 3D glasses can adapt to the motion rule of the eye balls of the human body and use comfort is high.

Description

technical field [0001] The invention belongs to the field of glasses, in particular to 3D glasses. [0002] Background technique [0003] 3D glasses are often used when watching stereoscopic movies in cinemas. 3D glasses mainly use the principle of polarized light to show the two sets of films taken by two cameras synchronously, so that the two slightly different images are superimposed on the screen, and a polarizer is installed in front of each movie camera. From the light emitted from two projectors, after passing through the polarizer, it becomes polarized light. The polarization directions of the polarizers in front of the left and right two projectors are perpendicular to each other, so the polarization directions of the two beams of polarized light produced are also perpendicular to each other. These two beams of polarized light are projected on the screen and then reflected to the audience, and the direction of the polarized light does not change. The audience use...

Problems solved by technology

If this kind of lens is used to make 3D glasses, it is still unavoidable that when the pupillary distance of the viewer is not suitable for the pupillary distance of the glasses, and when the viewing distance is not suitable, it is easy to see the problem of not being able to see the picture clearly.
