Our sense of depth perception and ability to see in 3 dimensions are often-overlooked benefits of our complex visual system.
Our eyes gather a significant amount of visual data as we observe our surroundings. Both eyes send this gathered data back to the brain, where it is interpreted and combined into a single cohesive image.
The fact that the eyes are set a small distance apart from each other allows them to gather slightly different sets of visual information, which the brain interprets as depth and distance when combining the two images. This produces 3-D vision.
3D vision plays a key role in a child’s ability to learn in school. Children who have problems with 3D depth perception will often have difficulty with spatial skills and visualization. This impacts their ability to form letters correctly, develop accurate word memory and easily understand complex shapes. These challenges can significantly undermine their reading speed, spelling abilities, handwriting, understanding of mathematics and comprehension.
3D vision is especially important in subjects such as geometry, where a sense of depth and space are essential to understanding basic concepts.
In sports like basketball, football and soccer, it’s essential to know where other teammates are standing on the field or court in order to pass the ball. It’s also a key part of catching incoming passes and judging the distance to the basket or goal post.
In baseball, 3D vision is necessary for sizing up the ball as it comes across the plate, for judging distances, swinging, catching and hitting, and running the bases.
Driving safely is absolutely tied to depth perception and the ability to see in 3D. Without them, drivers may not be able to avoid hitting other cars, know when it is safe to change lanes, and how far to go when backing into or moving out of parking spots to avoid other cars, the curb or pedestrians.
Accurate 3D vision is particularly important at night, where there are fewer visual cues, such as the size and movement of nearby objects, to make quick decisions.
Even the most basic day-to-day tasks, such as shaking another person’s hand, are made easier with proper depth perception and 3D vision.
3D vision also makes the world around you safer. Crossing the street requires you to estimate the distance between yourself and any cars that may be on the street, as well as the speed those cars are traveling. Even walking downstairs can be hazardous if you can’t properly gauge the distance from each step down to the next.
If you’re experiencing difficulties with 3D vision, speak to your eye doctor about vision therapy. This doctor-prescribed, evidence-based regimen of in-office and at-home eye exercises helps reset and strengthen the connection between your eyes and your brain. For 3D vision, this means helping coordinate the signals coming from your brain to each eye, so that the eyes can move and focus in unison.
