It is undeniable that some users get dizzy with VR glasses. In addition, 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 no more than using other electronic devices with a screen. Yes, it may seem like it has nothing to do with virtual reality in general, but there is a connection. Ultimately, both can cause severe dizziness.In addition, it should also be borne in mind that with some 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. Basically, to achieve a three-dimensional effect, they project an image onto each eye. Thus, the effect of an ordinary flat television screen on which two eyes look at the same image is eliminated.The result is fascinating, but it also demands extra effort from the brain. This is why fatigue can occur after a while. In addition, the screen (or screens) is very close to the eyes. Therefore, they must be constantly developed. As a result, certain eye muscles called ciliary muscles have to work harder, which also causes eye strain. If we add to all this that the light falls directly on our eyes, it is clear that after a while we risk having a headache.Virtual reality makes some people very dizzy. This is because the brain receives the same signals it would receive if we were moving. But it’s not. This leads to a mismatch between the signals received by the vestibular apparatus of the ear, which is responsible for balance, and what the eyes see. This is why dizziness occurs. This 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 might not be for you. Virtual reality glasses.image source: freepik.com
Can everyone benefit from virtual reality glasses
Aside from dizziness and eye strain, VR glasses are generally harmless. However, people with strabismus or amblyopia may not be able to use these devices. This is due to the fact that the first has a displacement of both eyes, and the second has an imbalance in the visual power of each of them. Therefore, it is not possible to properly 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 fully enjoy virtual reality.Ultimately, virtual reality may not be for everyone. Perhaps those most prone to dizziness would prefer to avoid them. And those who can’t see it in all its glory won’t consider the costs worthwhile.See also: “Cappuccinatore coffee machines: what to look for when buying.”
