Eye Doctor on Depth Perception & Your Vision
1. What Is Depth Perception?
Establishing the distance between items and seeing the world in three dimensions is known as depth perception. One or both eyes can judge distances by picking up on depth cues. Monocular cues are used when determining distance with one eye, while binocular cues apply when looking with both eyes. There are also inferred cues, which is when monocular and binocular are used to judge differences.
2. How Do Eyes Determine Distance?
When facing something head on and moving your head from side to side, the object will move but background objects will not, which is known as moving parallax. Close up objects are viewed using stereo vision, meaning that each eye is receiving a different image of that object. These differences can translate into info regarding distance. Your brain will also store information on the size of objects viewed in the past, and use this information to calculate the size of the object on your retina.
3. What Causes Poor Depth Perception?
Trouble with depth perception typically occurs as a result of an eye condition. Crossed eyes or strabismus is a misalignment of the eyes that may make it difficult to accurately judge distances. Depth perception can also be affected by the presence of a lazy eye, which occurs when signals from the brain to the eye are not being received. If you think you have poor depth perception, schedule an eye exam as soon as possible to pinpoint the cause.
