Virtual reality and possible effects on health
Virtual reality and augmented reality are gaining momentum as promising new technologies. They can potentially expand the field of human knowledge by changing the way people learn, work, play and entertain themselves.
In fact, some technology experts even proclaimed 2016 as “The year of virtual reality”. Surprisingly, there has been almost no debate about the health and safety risks associated with attaching VR headsets to their eyes. There could be health risks when people are immersed in a totally imagined environment, which may affect their physical and emotional well-being
Here are some of them:
1. Anxiety
The immersive nature of virtual and augmented reality can induce stress or anxiety after using a complete occlusion handset for more than a few minutes.
Depending on the images they see, virtual reality can bring waves of emotion more than just looking at photos or watching videos. For example, virtual reality images of the war in Syria can cause the viewer to feel fearful, stressed and shocked.
2. Nausea
Some people who use headphones with RV complain of dizziness and nausea. Their realistic simulated movements can affect a person’s perception of time and space and can cause fatigue, nausea or dizziness.
In fact, a study from the UCLA Keck Center for Neurophysics showed negative side effects of virtual reality among laboratory rats, including “cybernetic disease” and abnormal activity patterns in rat brains. Scientists also noted that 60 percent of rat neurons simply shut down in virtual reality environments.
3. Eye strain
VR headsets can cause severe eyestrain among users. They hang their eyes to focus on a pixelated screen that uses a single optical refractive element. The headphones usually do not address optical problems with devices near the eyes, and quickly become uncomfortable after a few minutes.
Headphone designers must find a way to maintain a large field of vision for users. Humans generally have a 200-degree field of vision, which involves 140 degrees of binocular vision for depth perception, and 60 degrees for peripheral vision.
The current headphones have 35 degrees of FoV, which gives the user the experience of simply “watching” the content. Increasing it to 60 degrees of FoV or more can make users feel completely immersed in the content that is shown and becomes experiential.
4. Exposure to radiation
Wearable technology, such as VR headphones, exposes the user to harmful electromagnetic frequency radiation. These devices make use of wireless connections such as Bluetooth or WiFi to connect with your smartphone or computer; and they are equipped with smart sensors that allow you to immerse yourself in the virtual reality experience.
Some virtual reality headsets use smartphones, which emit radiation. Numerous studies have already pointed out how cell phone radiation can affect the human reproductive system, interrupt sleep or cause mood swings. Now, VR hearing aids work in conjunction with cell phones and can be connected wirelessly to Wi-Fi, which means that they also emit radiation and, in fact, could pose long-term health risks.
