What causes poor depth perception?
Causes of Poor Depth Perception Crossed eyes are a sign of strabismus. Another factor is amblyopia or lazy eye, which occurs when the brain function favors one eye. This results in one eye failing to track properly. Trauma to the eye, blurry vision and nerve problems can also cause poor depth perception.

How many eyes do you need to have depth perception?
In order to have depth perception, you must have binocular vision, also known as stereopsis.
