Visual perception is the ability to interpret information and surroundings from the effects of visbile light reaching the eye. The resulting perception is also known as eyesight, sight, or vision
Depth perception is the visual ability to perceive the world in three dimensions and the distance of an object.
Depth sensation is the ability to move accurately, or to respond consistently, based on the distances of objects in an environment.
I will write more about the symbolism of this and compare it with our Spiritual Vision (eyesight), our Spiritual Depth perception and our ability to move accurately in the world in which we live.
