Visual adjustment device based on HMD device

Abstract

The present invention provides a visual adjustment device based on an HMD device. The visual adjustment device based on the HMD device comprises a form module, an acquisition module, a near point training module and a far point training module; the form module is configured to create a form, input conditions of the form comprise refractive power of eyeballs, and output results of the form comprisea near point position and a far point position for vision training; the acquisition module is configured to acquire the refractive power of the first eyeball and obtain the corresponding first near point position and first far point position from the form; the near point training module is configured for near point training: reciprocation motions of a display screen between a near point and a farpoint are controlled; and the far point training module is configured for far point training: the reciprocation motions of the display screen between the far point and a super far point are controlled. The visual adjustment device based on the HMD device can help users to perform the far and near point vision training anytime and anywhere, can control myopia degrees and restore vision for users with poor vision, can also eliminate or mitigate eye fatigue caused by long-term film and TV watching, and can effectively prevent the myopia.

Description

technical field [0001] The invention relates to the technical field of visual function training, in particular to a visual adjustment device based on HMD equipment. Background technique [0002] In addition to wearing glasses to obtain better vision, teenagers with poor vision can also participate in far and near point vision training courses to restore vision. The linear trainer is a kind of equipment used for far and near point vision training. In the far and near point vision training, the user first wears myopia glasses, and then puts his head on the bracket. Ask the user if they can still see clearly. When the user answers that they can't see clearly, stop moving the object of gaze and set the position of the object of gaze as the near point at this time, then zoom out the object of gaze, and determine the far point in a similar way . Then you can perform near-point training and far-point training: the so-called near-point training is to move the gaze back and forth b...

Problems solved by technology

[0003] The above far and near point vision training methods can indeed restore people's vision to a certain extent, but for ordinary people, they not only have to pay high quality costs, but also need to go to hospitals or clinics equipped with this straight line training device. For teenagers In general, most of the time is spent on studies, and it is impossi...
