Will Wearing VR Glasses Cause Myopia?
Now VR glasses are popular among young people especially when they play games. But do you wonder whether VR glasses will cause myopia?
It depends on whether you use it properly, but VR glasses are more likely to cause myopia than other electronic products.
Some people have done experiments on whether VR hurts the eyes, and found that if a person stays in the VR environment for more than 20 hours, the whole person is not good when he comes out.
After watching a movie by using VR, we take off the VR glasses and look at other things in far distance, you will feel that things are divided into two, two eyes see different things. This is because wearing VR for a long time makes brain unable to overlap images of the two eyes.
VR vision is different from what we usually do with our eyes. It uses two eyes to look at their respective lenses. Although there is only one screen, there are two light source paths, so contraction of orbicularis oculi muscle is different from seeing the real scene with the naked eye.
At the same time, because the convex lens enlarges the screen, it makes people feel that screen is far away, but actually very close. The tension of ciliary muscles does not match the inherent visual habits of the brain.
These two differences will give the brain an illusion, causing people to be unable to adapt to the real scene immediately after taking off their glasses. If you don’t adapt, your brain can automatically adjust it back, but if you use it for a long time, especially if you fall asleep immediately after using it at night (don’t give your brain a chance to adjust it back by observing the real scene), this illusion will accumulate and form new visual habits, which will cause myopia, hyperopia, astigmatism, astigmatism, strabismus and other results.
What’s more, wearing VR glasses just like using a mobile phone in a dark environment. Eyes directly receive light stimulation, which can easily cause light damage to the retina. In addition, the product is heavier and the neck pressure is higher, especially for children, this kind of damage will be greater.
Now, we all know that blue light hurts eyes and long-term blue light exposure can cause eye fatigue and decreased vision. In fact, the white light manufacturing principle used in VR is the same as that of computer phones. VR also produces short-wave high-energy blue light.
There is a certain limit to our eyes tolerance. If you overuse your eyes, it will certainly cause damage to your eyes.
