In this sense, an experiment carried out at Johns Hopkins University revealed that when we suffer tunnel vision, our ability to listen also decreases. We stop paying attention to them because they are not relevant to us at that time. We not only stop seeing some stimuli but also to listen to them. In fact, the tunnel effect affects not only our vision but also our hearing. In practice, we see less not because we have a visual problem but because our attention is restricted. In this case, reference is made to attentional narrowing and it is not usually limited only to our visual field. Tunnel vision can be due to stress and anxiety. The tunnel effect affects our perception globally This phenomenon, which is also defined as “tubular field”, is like seeing through a tube that covers our eyes. We can see well in a straight line but the vision to both sides is very limited. In fact, the definition of tunnel vision indicates a restricted field of vision in which we maintain central vision, but almost completely lose peripheral vision. We can also suffer tunnel vision due to anxiety and stress. However, this tunnel effect does not only occur when we drive at a certain speed. It is as if the world around us suddenly ceases to exist. Obviously, the more the speed increases, the narrower our field of vision becomes. What is on the sides fades to practically disappear. It is estimated that at 130 kmh (81 mph), our angle of vision is only about 30 degrees, so we can only see clearly what is in front of us. When we drive too fast, our vision narrows, so that we are unable to see what is happening in our larger environment. So our critical thinking is reduced and we make impulsive decisions that may not be the most appropriate. This phenomenon occurs fundamentally when we are highly stressed and face danger. Tunnel vision can blind us to a part of reality, literally.
