3D VISION

 

 

 

Have you ever gone into a movie theatre to watch a 3D movie?  What was the experience like?

Not everyone has the ability to see in 3D.

But most people have the ability to see in 3D—or three dimensions.  This is called Depth Perception.  Depth Perception is the ability to distinguish the position of objects relative to spatial location of other objects.  Depth perception allows us to judge distances, size of objects relative to each other and allows us to avoid bumping into things. 

Some people do not have the ability to see in 3D.  They may have a condition called Amblyopia or Strabismus.  We will discuss this in a later post.

What is fusion?  Fusion, which is a function, is necessary to be able to see in 3D.

Fusion is the ability of the two eyes to see an object as a single image.  Eye movement coordinated to fuse two images into one

Eyes must be parallel when looking straight ahead.  This results in binocular vision.

Eye muscles must be coordinated and working in unison.  Each eye must have good vision.  A lot of people misunderstand 'normal vision' for 'perfect vision.'  I will discuss this later on.
