Magic Eye hidden 3D images

What does it take to see life in 3D...not to mention 3-D stereograms, stereoscopic photographs, or 3D TV or movies, such as Avatar 3D? On this page, you will learn about an exciting part of normal human vision - stereovision (aka, stereoscopic vision or stereopsis). For now, let's just keep things simple and call it stereovision.

Human Beings with Two Eyes that Work Together Have Stereovision

Human beings generally come equipped with two eyes and one head. If you have any doubts about your equipment or your ability to see 3D, check out Why Some People Have Trouble Seeing 3D before continuing.

Unlike horses, humans have two eyes located side-by-side in the front of their heads. Thanks to the close side-by-side positioning, each eye takes a view of the same area from a slightly different angle. The two eye views have plenty in common, but each eye picks up visual information the other doesn't. Have you ever compared the different views of your right and left eye? The Eye Hop Game lets you do just that.

Two Eyes = Three Dimensions (3D)!

Each eye captures its own view and the two separate images are sent on to the brain for processing. When the two images arrive simultaneously in the back of the brain, they are united into one picture. The mind combines the two images by matching up the similarities and adding in the small differences. The small differences between the two images add up to a big difference in the final picture! The combined image is more than the sum of its parts. It is a three-dimensional stereo picture.

The word "stereo" comes from the Greek word "stereos" which means firm or solid. With stereo vision you see an object as solid in three spatial dimensions width, height and depth or x, y and z. It is the added perception of the depth dimension that makes stereo vision so rich and special.

3D Image Hidden Has Many Advantages

Stereo vision or stereoscopic vision probably evolved as a means of survival. Con la visión estéreo, podemos ver dónde están los objetos en relación con nuestros propios cuerpos con una precisión mucho mayor, especialmente cuando esos objetos se mueven hacia nosotros o lejos de nosotros en la dimensión de profundidad. Podemos ver un poco alrededor de objetos sólidos sin mover nuestras cabezas e incluso podemos percibir y medir el espacio "vacío" con nuestros ojos y cerebros.

If You've Got Stereo Vision, Count Your Blessings!
