In fact, VR head wearing equipment really harmful to the eyes, the following us to come with everyone to explore! 

Scientific experiment for VR name! 

Beijing's future image high-tech innovation center released a report on the impact of long-term use of VR head-on display equipment for low-age users' vision, "and is also known as VR! 

The experiment was conducted by Beijing University of the future high-tech innovation center joint Beijing University of Technology and other units, a total of 50 students from the fourth and sixth grade students participated in the test. The duration of each test was 60 minutes. The 60 minutes were divided into three stages of wearing VR equipment. Each stage was 20 minutes long. After each stage, the subjects completed the visual fatigue test and collected the visual acuity chart Box data.  

Test data results let us surprise found, VR on the eyes of young users not only did not hurt, but the effect of treatment:

First, subjects who used VR head-mounted displays within one hour were mostly flat or raised. As can be seen from the data, 1 hour after the experiment, VR subjects were flat or rising in the proportion of the total number of 90%, only 10% of the visual decline.

Second, after 1 hour of continuous use, the panel group subjects only rely on 20 minutes of rest, can not restore all eyes to the state before the experiment; VR group showed a more positive change.

Third, the younger users are more likely to be affected by the visual impact of the head over the flat panel. Twenty minutes after the start of the experiment, 28% of the VR subjects had a change in visual acuity, compared with less than 20% of the tablet, indicating that the visual impact of the VR subjects was higher than that of the tablet in 20 minutes. 

In summary, if the headset display device virtual image distance design is reasonable, then the VR device can even play a better role in visual correction.
