Augmented Reality is the overlaying of a digital image over a real image in real time. The most advanced example is the new Google Glass. A small screen is mounted on a pair of glasses and placed in front of the eye. Along the side of the glasses is a cpu with a mini projector that produces a slightly transparent image in your field of view. It's a wearable smartphone. But how does it not create eyestrain being so close to the eye? As long as the image appears like it is coming from the distance, the eye doesn't have to actively focus on it. The focusing muscles can stay completely relaxed to see the image. This is done by using a prism in the eyepiece that redirects the projected image directly onto the fovea of the retina and simulating a far off image.
Many of the most perplexing optical illusions are drawn, painted, computer-generated, or tricks of nature. Sometimes it just takes a good camera angle and a playful cat. This illusion is created by superimposition which is when one object is placed over another. The brain can be tricked into seeing a new image if the superimposed objects are close enough in color, size, positioning, and shape. So, no, you're not developing CATaracts. It's just an optical illusion.
Photographs created by Dr. Faktorovich were chosen for the Annual Photography Show exhibit at the Palace of Fine Arts. Opening reception is on May 22nd from 7 to 9 pm. (http://www.aaugalleries.com/2013/05/06/aau-spring-show-2013/)
