VR popular science education knowledge: VR devices can cause eye myopia?
today we are here and you take a look at knowledge about VR popular science education: VR devices can cause eye myopia? With the rapid development of society, now VR products quickly flooded into people's horizons, but also have a lot of problems we need to correct to treat, then what is? Then we'll take a look at.
how close VR devices, the equivalent of staring at the mobile phone to play games, will accelerate myopic.
in fact, studies have shown that the adjustment of the lens is based on the awareness, which means you can see in the VR scene is far from you, relax the brain consciousness will also control the lens, the opposite will search, so this please rest assured.
but VR product really has no harm to the eyes, reflected off is at present products are easily fatigue, time is too long to dry. Analyzed the main reason or don't match. This thing is not like our glasses after all, the private ordering. Mainly mismatch is embodied in the following aspects:
some products distance cannot adjust
some products of myopia hyperopia the adjusting range is limited and inaccurate
fatigue caused another reason I think is some product was too hot, also have oppression to face, if the center of gravity forward design, the neck is not comfortable.
the regulation of VR glasses for users of eye myopia is better means a lot. VR glasses when adjusting the object distance currently on the market are two eyes change at the same time, and to the left and right eye myopia degree of myopia people so much inconvenience. Fuhua VR glasses adjust solution using 3 gear box. 4 mm planetary gear precision of three transmission gear box structure compact enclosure structure in each lens built-in automatic regulating motor, intelligently adjust VR glasses.
choose the focal length, distance adjustment function of the VR glasses is difficult. Normally each person's face and facial feature location will be different, want to use a set of mold to satisfy all users is a fable, so a good quality of VR glasses, at least has a focal length adjustment function. To achieve the focal length of the VR glasses regulating function, we used to adjust the motor gear box structure in combination with the multi-layer development design can transform ratio mechanism to adjust the motor parameters, the product has a secondary, tertiary, quaternary transmission changes according to the performance ( Motor) Motor drive demand change reduction ratio and adjusting the rotational speed and torque of the gear box input, from driving on the way to solve VR glasses adjust intelligent driving demand at all levels.
so personal think VR is not a disaster, is a new product, we don't need too afraid. But at the same time we also don't use for a long time, after all, and real outdoor overlook and distinction, use of eye fatigue caused by long periods of time can also accelerate the development of myopia.
