In technical terms this kind of vision is part of the normal vision that occurs outside the center point of your gaze. In other words, if you have this kind of vision problem then it means that you don’t actually see objects or surroundings in the normal wide angled way although you may be able to visualize things at the center of your gaze. This kind of vision problem that some people experience is also known as tunnel vision. Studies have revealed that generally human beings have lesser peripheral vision than that of animals.
