That’s also why it’s so important to start taking care of your vision from a young age. That’s why it’s so difficult for people with poor vision to engage in professions like aviation or medicine. They may only face difficulties with higher level skills such as performing surgery or being an airline pilot. Their body has made adjustments to compensate for the switch from binocular to monocular vision. It functions well enough for them to do day-to-day tasks in a safe manner. So what happens if you suffer a debilitating injury in only one eye? An interesting fact about people with only one eye with functioning vision (over a long period of time) is that they usually have an acceptable level of depth perception. Eye injuries can also cause sufferers to experience trouble with depth perception while they are healing. People who are cross-eyed (strabismus) or have a lazy eye (amblyopia) often struggle with this part of their vision. People with normal, or binocular vision (vision created by two separate eyes working together to form a single image), can perceive the depth and distance of objects. In Technical Termsĭepth Perception is also known as stereopsis. It usually occurs unconsciously and happens thousands of times a day without you ever realizing that you are using it. One way depth perception allows us to do this is by taking previous knowledge and using it to understand the world around us. This type of perception is responsible for forming an idea of the length, width and height of an object. Your two eyes look at the object from different angles and that information is processed in your brain to form a single image.

It takes both eyes working in sync to look at an object and develop an informed idea about it, like its size or how far away it is. But what exactly is it?ĭepth perception is the human eye’s ability to see in three dimensions and judge the distance of an object. Maybe after your friend stubbed their toe, they grumbled about their depth perception, or maybe your little brother tried on your glasses and totally lost his depth perception. We’ve all heard of the words “depth perception” before.
