Pros and Cons of Virtual Reality

Virtual reality is one of the hottest tech products in today’s society. This technology has numerous applications in various sectors.


Virtual reality (VR) is a computer-generated technology which allows the user to explore and interact with a digital environment by using their bodily senses. A VR headset fits snugly around the head and eyes, and images are portrayed to the eyes using 2 small lenses (digital screen), effectively visually separating you from whatever space you are physically occupying. Through VR, you can visit Niagara Falls, hike Mount Everest, and drive a Ferrari - without getting off your couch. This is what makes virtual reality so unique; it enables people to experience things they only dreamt of before. In a virtual world, objects appear far away, but in reality, they are only a few centimeters from the eye (through the headset). VR essentially tricks the eye into believing that there is more space between the eye and the object they are viewing.



Lately, virtual reality’s benefits have been surfacing in education, notably in vocational training. Many driving students initially have a fear of driving. So, instead of them behind the wheel of a real car, VR driving simulation can effectively enable drivers to learn the basics and practice how to drive safely. Once a student completes a full VR driving course, he/she will generally feel more comfortable driving in reality. Another application of VR in training flight crashes and emergencies are also a matter of concern. Last year alone, there were roughly 100 related airplane incidents. Similarly, novice pilots use VR to master how to take off and land. This could essentially prevent major airline accidents. Medical staff and practitioners can also do run-throughs on a range of medical emergencies and scenarios in a VR simulated environment.

VR has also revolutionized the entertainment industry. Gaming companies have teamed up with tech companies to create headsets which enable players to experience virtual world. User can interact with objects and turn an onscreen experience to a real life experience. The Oculus Rift and HTC Vive are two VR headsets that do just that. These high tech products allow for video games to be considered more than just an onscreen experience. Consumers are able to immerse themselves in the video game, playing the roles of major protagonists, athletes, and characters.


The everyday buildings that you see on your way to school or work could also be a result of VR. Applying virtual reality in architectural engineering allows engineers to not only visualize their creation, but also create a realistic model of it. With this technology, architects and engineers can map out whole cities before even building them!


VR may seem like the best innovation created by man, but it has its fair share of drawbacks. Most notably, the negative health effects. Long exposure to VR devices can lead to myopia, a disease that causes nearsightedness. Not only that, but it can make you feel dizzy and light headed. Many people who excessively use VR complain of headaches, eye strains, and even nausea. Technology experts recommend a 10 to 15 minute break for every 30 minutes used in order to avoid many of the side effects above.

When used in moderation, VR is a beneficial product. The benefits will outweigh the detriments - as long as you take short breaks in between each VR session and limit yourself to a certain number of hours per day.
