At first I was very dubious about how well a pair of £50 glasses could work. The eDimensional website provides a very good explanation that describes the technique they use to make images pop out right in front of you. Their secret is based around stereovision.

“Stereovision is actually the normal way almost everyone sees in the real world. We all have two eyes and perceive depth by a mental interpretation of the world we view through those two eyes. Each eye gives a slightly different perspective on the objects viewed and this slight difference provides depth cues to our brain”

This explains the key behind seeing in 3d but not how the glasses help create a virtual reality. The graphics card drivers play a vital role in producing a picture that the glasses can then make into a 3d image.

“The E-D software and drivers automatically convert the images on your monitor into a left and right perspective. Each image flickers back and forth so fast on your monitor that it is not noticeable to the human eye. Working with our active glasses, the flickering of each image is timed with flickering of the left and right lens of the glasses, again faster than can be perceived. Thus, stereovision as it pertains to viewing a virtual world means that you have the capability to produce two separate images and that each eye sees only one of the two images. If this is done correctly, your mind will combine the two images in such a way that you actually have the perception of being "in" the virtual world rather than just viewing a picture of the virtual world”

The above picture might not look much but with the E-D glasses its completely different!

The glasses allow you to perceiving depth "into" the monitor but also objects can appear to come “out of" the monitor. As eDimensional say, you have to see to believe. There is no way you can see the results the glasses produce in this review but hopefully I can make you believe in the concept and at least describe how true the 3d is. eDimensional offer a money back guarantee on the E-D glasses with which is reassuring.

So without further ado let’s crack on with looking at what you get for your £50 and how to go about setting up the glasses.
