Is virtual reality dangerous for the eyes?

Now that PlayStation VR is making a splash, many people want one, but looking back on that day they took a virtual tour of a museum and almost ended up throwing up, they don't want it.

Thus, it is undeniable that virtual reality glasses make some users dizzy. And they also tire the eyes a lot. But are they really dangerous?

Disadvantages of virtual reality

One of the main concerns about virtual reality is the potential for eyestrain and fatigue. Because virtual reality headsets typically use lenses to create the illusion of depth and immersion, users may need to focus their eyes at different distances than they are used to, which can cause eyestrain and discomfort.

Both PlayStation VR and other virtual reality glasses have a relatively simple mechanism. Basically, to get that three-dimensional effect, they project an image onto each eye. Thus, the flat effect of a normal television screen, in which both eyes rest on the same image, is eliminated.

However, this is generally not a serious or long-lasting problem, and most users can adjust to the experience over time.

There is also some concern that prolonged use of VR could lead to more serious eye problems, such as myopia (nearsightedness) or amblyopia (lazy eye).

However, there is currently no conclusive evidence to support these claims, and many experts believe that virtual reality is unlikely to cause long-term eye damage.

That being said, it's always a good idea to take breaks and rest your eyes when using any type of digital device, including VR headsets. Additionally, some people may be more sensitive to the effects of virtual reality than others, and it is important to be careful and follow best practices when using virtual reality technology.

This may include taking breaks, adjusting settings to minimize eye strain, and consulting with a healthcare professional if you have any concerns.

How virtual reality is dangerous for the eyes?

There is some concern that prolonged use of virtual reality (VR) technology could be potentially harmful to the eyes, but the evidence on this topic is still limited and inconclusive. Here are some of the ways that virtual reality could potentially be dangerous to your eyes:

• Eyestrain and Strain: Virtual reality headsets use lenses to create the illusion of depth and immersion, which can cause your eyes to focus at different distances than they are used to. This can cause eye strain, fatigue and discomfort, especially if the user wears the headphones for long periods of time.

• Motion sickness: Some people experience motion sickness or nausea when using VR, which may be due to a disconnect between the movement perceived by the eyes and the lack of movement felt by the body. This can cause discomfort and can also affect the eyes.

• Nearsightedness (nearsightedness): There is some concern that prolonged use of virtual reality may contribute to developing nearsightedness, especially in children and young people. This is because your eyes can get used to focusing at close ranges while using VR, which could affect your ability to focus on distant objects.

• Blue light exposure: Like other digital devices, VR headsets emit blue light, linked to eyestrain, sleep disruption, and other health problems. Some experts have raised concerns about the potential long-term effects of blue light exposure from VR headsets.

Can everyone enjoy PlayStation VR?

Beyond dizziness and eyestrain, virtual reality glasses do not usually pose risks. However, as the American Ophthalmology Association explains, people with strabismus or amblyopia may not be able to enjoy devices like PlayStation VR.

This is because the former presents misalignment in both eyes and the latter an imbalance in the visual strength of each one of them. Therefore, the three-dimensional image cannot be reconstructed correctly.

That doesn't mean it's dangerous for them, just that they won't be able to enjoy the full experience.

Ultimately, virtual reality may not be for everyone. People most prone to dizziness may prefer to avoid it. And those who cannot see it in all its splendour do not consider the expense profitable. But given the sales of PlayStation VR, it's clear that a lot of people were willing to give it a try. There must be a reason.
