Abstract
A single-screen 2D myopia-preventing digital glasses is characterized in that a digital camera is mounted in front of a single-screen head-mounted display and located in the middle of the display, images captured by the digital camera display left and right identical images by taking a left middle line and a right middle line of the display as boundaries, the distances between the pupillary distance and the picture center points of the left and right images are identical, the left and right eyes of the user respectively see the identical image through an eyepiece, and the two eyes of the user see the naturally overlapped 2D image. The invention can effectively prevent the generation of myopia from the etiology and promote the recovery of pseudomyopia by using the indirect visual object to visually convert a short-distance visual object into an infinite long-distance visual object.
Description
The technical field is as follows:
the utility model relates to a glasses especially relate to a 2D digital glasses.
Background art:
the two eyes of a person have a certain distance, the person can shoot the same object like two cameras which are about 6cm away from each other when looking at the object, two images with different left and right positions are captured, the brain of the person has the fusion capability, and the two images with different positions can be fused together, so that the person can clearly see the object and obtain the stereoscopic impression. The left and right positions of the object images seen by the left and right eyes of the same object are greatly different when the object is short-sighted, the brain can complete the fusion only by using larger fusion force, the left and right positions of the object images seen by the left and right eyes of the same object are slightly different when the object is long-sighted, and the brain can complete the fusion by using smaller fusion force. The eyes have the adjusting capacity, the left eyeball and the right eyeball are pressed to be converged towards the middle of two eyes by the adjusting force generated by the contraction of eye muscles when objects are viewed at a short distance, the object image position difference seen by the left eye and the right eye is reduced by using the near interpupillary distance object, and the fusion of the brain is favorably completed. The premature minors with immature eyeballs need to use the adjusting force to press the eyeballs regularly and for a long time to cause the deformation and the bulge of the eyeballs and the lengthening of the eye axis to form the myopia. The physiological characteristic that a certain distance exists between two eyes of a human cannot be changed, and minors need frequent and long-time short-distance objects such as reading, writing and the like, which are inevitable in the current society, so that prevention of myopia from the cause seems to be an unrealizable desire, and the myopia becomes one of the diseases with the highest incidence all over the world. The existing glasses with the myopia prevention function in principle only have triple prism myopia prevention glasses, an object image seen by two eyes of an object through the triple prisms is a virtual image after displacement, and the left eye diagram and the right eye diagram have no potential difference, so that the myopia prevention effect is achieved. Since the displacement distance of the virtual image is related to the degree of the triangular prism and the distance between the triangular prism and the object to be observed, and the distance between the eyes of the user and the object to be observed is uncertain (for example, the distance between the first line of characters and the last line of characters on reading and the posture change when reading and writing), the triangular prism with accurate degree cannot be prepared, and the myopia prevention effect is poor. If the distance of the object is beyond the specified distance, the triple prism myopia prevention glasses can damage the glasses, the myopia degree is increased, and the damage degree to the eyes is larger when the straight line of the object is changed into oblique line and double image. Triple prisms are impractical for myopia prevention. With the development of society, the aggravation of learning tasks of minors, the increase of the utilization rate of digital products such as mobile phones needing to be watched in a close range and the like, the incidence rate of myopia is higher and higher.
The utility model has the following contents:
