Description
Technical field
The invention belongs to eyewear art, particularly relate to a kind of 3D glasses.
Background technology
When watching three-dimensional film at the cinema, often can use 3D glasses.3D glasses mainly utilize the principle of polarized light, and the two groups of films taken with two video cameras are synchronously shown, and make these slightly differentiated two width images overlap in screen, before every frame projector, load onto polaroid.From the light of two frame projector injections, after polaroid, just become polarized light.The polarization direction of the polaroid before the two frame projectors of left and right is orthogonal, and the polarization direction of the two bundle polarized lights thus produced is also orthogonal.This two bundles polarized light projects in screen and reflexes to spectators place again, direction of polarized light does not change. and spectators watch with above-mentioned polarising glass, every eyes only see corresponding polarized light image, namely left eye can only see the picture that left machine mirrors, right eye can only be seen will produce stereo perception by the picture that right machine mirrors like this as direct viewing.But reality during viewing, there will be some problems in movie theatre.First, everyone interpupillary distance is different, and when viewing person's right and left eyes accepts polarized light, if do not wear the suitable 3D glasses of interpupillary distance, the angle that right and left eyes can be made to receive polarized light has some gaps apart from theoretical value, fuzzy when causing viewing, occur ghost image; Moreover, seat rearward or the not good enough viewing personnel of eyesight own easily because the factors such as sighting distance is relatively long cause not seeing picture.And current 3D glasses do not have special in these problems when designing, therefore adaptability, dirigibility are lower in use.
See disclosed " Zoom lens and glasses " in Chinese patent literature, notification number is CN101506714A, this Zoom lens and glasses comprise the ring that has front surface and rear surface, in the middle of the front surface and a hard transparent front casing of ring, an elastic film is set, the rear surface of ring is adhered to a rear casing (can select to arrange the second elastic film in the middle of rear casing and ring), the chamber of a filling liquid is formed in the middle of elastic film and rear casing (or second elastic film), the curvature of elastic film is changed by the amount of liquid changed in chamber, thus change the optical property of lens.The ring of lens can have color, can be maybe transparent, translucent or opaque.In addition, the outward appearance of framework can be obtained by a bonding trim in the front portion of ring.These lens can be used to make varifocal glasses.If this kind of lens are used for making 3D glasses, still can not avoid when viewing person's interpupillary distance and glasses interpupillary distance improper time, and when viewing distance is improper, easily there is the problem not seeing picture.
Summary of the invention
The object of the invention is 3D glasses in order to solve prior art easily because the factors such as interpupillary distance, viewing distance are improper cause viewing person to watch unclear deficiency, provide a kind of can flexible, strong adaptability, allows beholder clearly can watch the 3D glasses of film.
The present invention is achieved by the following technical solutions:
A kind of 3D glasses, comprise mirror pin, nose frame, described nose frame two ends are provided with the polarisation mirror holder of a pair connection mirror pin, polarized lenses is provided with in described polarisation mirror holder, described polarisation mirror holder is provided with some to sub glasses holder, be provided with the adjustment eyeglass with sub glasses holder grafting in described sub glasses holder, described adjustment eyeglass is convex lens, and described nose frame comprises relatively-movable left semi-frame, right semi-frame.Play film leading portion pilot part time, viewing person can take out adjusting mirror sheet, then the relative position of left semi-frame, right semi-frame is regulated, thus glasses interpupillary distance is adjusted to the length of oneself viewing applicable, and, the adjustment of eyeglass interpupillary distance can also better must assist viewing person left and right eyeball to adapt to two groups of different polarized lights of angle, then coordinates the capsulociliary self-control of eyeball, can ensure to see image clearly; When viewing person thinks that the long viewing of sighting distance is unclear, adjusting mirror sheet can be inserted in sub glasses holder, till the image feeling to watch is comparatively clear.Because the present invention has above-mentioned regulatory function, therefore wide adaptability, will cause viewing unclear because of the equal factor of seat difference, eyesight own.
As preferably, described left semi-frame, right semi-frame are threaded, and the distance between each tooth of described screw thread is 0.5 centimetre, and described screw thread is provided with middle slot, and described left semi-frame, right semi-frame are provided with centering mouth.Regulate the spacing between polarisation mirror holder by turn, namely have adjusted interpupillary distance, often regulate one week, be equivalent to the interpupillary distance having changed 0.5 centimetre, utilize centering mouth and to middle slot, can be user and alignment identification is provided, be beneficial to the accurate alignment after nose frame rotation.
As preferably, the stepped arrangement of described sub glasses holder, a pair sub glasses holder far away apart from polarisation mirror holder, its central point line height is higher, and its central point wire length is also larger, and described sub glasses holder is rectangular.The eyeball of people, can with eyeball center for center of rotation when watching at a distance, and rotate towards outside and top, crystalline lens relative distance increases, and crystalline lens centre-height raises.And every a pair sub glasses holder is far away apart from polarisation mirror holder, central point line height is higher, has just in time adapted to eyeball to rotate this characteristic upward, can improve the viewing comfortableness of user.And eyeball rotates towards outside, mean that long sight interpupillary distance is greater than normal interpupillary distance, every a pair sub glasses holder is far away apart from polarisation mirror holder, its central point wire length is also larger, just in time adapt to above-mentioned characteristic, make the position of the adjustment eyeglass added corresponding with user's eyeball physical location better, reduce the capsulociliary self-control pressure of user, delay eyeball fatigue.
As preferably, described sub glasses holder outer side edges is provided with eyeglass socket, and described eyeglass socket is corresponding with adjustment eyeglass inner side edge.Do not need the adjustment eyeglass used, can take out from sub glasses holder and be inserted on eyeglass socket, conveniently collecting preservation, not easily lose.
As preferably, described sub glasses holder number is 3 to 8, and described polarisation mirror holder thickness is at least the twice of sub glasses holder thickness.Polarisation mirror holder connects nose frame, mirror pin, sub glasses holder, and its thickness is comparatively large, can ensure enough intensity, not fragile.
Therefore, the invention has the beneficial effects as follows: (1) can regulate interpupillary distance, make each viewing person can use the suitable glasses of interpupillary distance; (2) can add adjustment eyeglass, the auxiliary not good enough person of distance vision improves viewing sharpness; (3) position of the adjustment eyeglass added can adapt to the rotating rule of human eyeball, improves comfort, reduces the pressure of ciliary body self-control, delays eyeball fatigue.
