Is virtual reality dangerous for vision?
VR glasses can cause dizziness or eye strain. But not everyone is the same. But are they dangerous?
It's undeniable that some users are getting dizzy from VR goggles. Also, they are very irritating to the eyes. But are they really dangerous?
The truth is that, in principle, this is not the case. At least not more than using other electronic devices with a display. Yes, it may seem that this has nothing to do with virtual reality in general, but there is a connection. In the end, both can cause severe dizziness.
In addition, it should also be kept in mind that with certain eye diseases, it is not even possible to have a full virtual reality experience. That is, such a three-dimensional effect cannot be achieved.
Disadvantages of Virtual Reality
Virtual reality glasses have a relatively simple mechanism. In essence, to achieve a three-dimensional effect, they project an image onto each eye. Thus, the effect of a flat ordinary television screen on which two eyes are looking at the same image is eliminated.
The result is mesmerizing, but it also requires extra effort for the brain. This is why fatigue can occur after some time. In addition, the screen (or screens) is very close to the eyes. Therefore, they must be constantly in focus. As a result, certain eye muscles called the ciliary muscles have to work harder, which also causes eye fatigue. If we add to all this that the light falls directly on our eyes, it is clear that after a while we may get a headache.
Virtual reality makes some people very dizzy. This is because the brain receives the same signals that it would receive if we were in motion. But it's not. This leads to a discrepancy between the signals received by the vestibular apparatus of the ear, which is responsible for balance, and what the eyes see. That's why dizziness occurs. It does not happen to everyone in the same way, because not everyone has the same threshold at which these imbalances cause symptoms. However, if you get seasick on a boat or on a treadmill, virtual glasses may not be for you.
Can everyone enjoy virtual reality glasses
Aside from dizziness and eye strain, VR goggles are usually harmless. However, people with strabismus or amblyopia may not be able to use such devices. This is due to the fact that the first one has a displacement of both eyes, and the second one has an imbalance in the visual power of each of them. Therefore, it is not possible to correctly restore the 3D image.
This does not mean that these glasses are dangerous for them, it just means that they will not be able to enjoy the virtual reality to the fullest.
Ultimately, virtual reality may not be for everyone. Perhaps the people most prone to dizziness would prefer to avoid it. And those who cannot see it in all its glory will not consider the costs profitable.
