Description

Intelligence wear-type VR eyesight improves training equipment

Technical Field

The utility model belongs to the technical field of intelligent wearing equipment and specifically relates to an intelligence wear-type VR eyesight improvement training equipment based on VR technique, binocular vision technique, vision significance technique and brain wave detection technique is related to.

Background

VR equipment, VR head-mounted display, virtual reality wear-type display device promptly. The VR equipment utilizes the head-mounted display equipment to respectively provide different images for the left eye screen and the right eye screen, and human eyes generate stereoscopic impression in the brain and sea after acquiring the information with the difference, so that a user is guided to generate a feeling of being in a virtual environment.

Both myopia and hyperopia are generally caused by overuse of the eye, resulting in loss of activity of the eye muscles and reduced accommodative performance of the eye. When an eye looks at an object for a long time, the ciliary body can press the crystalline lens for a long time, so that the shape of the crystalline lens is bent, and the crystalline lens is changed due to the long-time pressing. That is, the eye looks near to far, primarily by the ciliary muscle stretching or compressing the lens, i.e., changing the lens diopter. It is theorized that vision can be enhanced by training the lens and ciliary body to look at different distances.

At present, two methods are mainly adopted for improving eyesight: wearing glasses and laser surgery treatment. For the treatment scheme of the laser surgery, the scheme can radically cure myopia, but the laser surgery is risky and has the possibility of relapse; for the scheme of wearing the glasses, the problem cannot be solved fundamentally when ordinary myopia and hyperopia glasses are worn, and the myopia degree can be deepened for a long time. In addition, various myopia auxiliary therapeutic apparatuses exist in the market, but more myopia auxiliary therapeutic apparatuses are inconvenient to use or have unobvious effects, the myopia auxiliary therapeutic apparatuses are not designed according to different mental states and eye degrees of users, and the myopia auxiliary therapeutic apparatuses really have a limited function of training crystalline lenses.

In recent years, the rapid development of VR technology, binocular vision technology, visual saliency detection technology, brain wave detection technology and related hardware technology provides a technical basis for the acquisition and application of mental states of users, so that the display of objects with different distances can be realized according to the binocular vision technology and the saliency detection technology, and the aim of training the crystalline lens and ciliary body of the user to restore vision is fulfilled. However, there is currently no relevant application in the field of vision improvement devices.
