According to Oliver Pasch, Sony’s Head of Digital Cinema Europe, 3D contact lenses are in
the product development pipeline. This was said during a discussion with Patrick Schappert from a
German web portal called Grobi.tv. No other details were released.
Based on the little information that was disclosed, we can make a few assumptions about this
technology. For one, it would have to be a passive form of 3D technology. Active technology
requires additional electronics to dissect the images. These extra electronics would not fit on a
contact.
There are currently two forms of passive 3D technology being used in today’s 3D
glasses. Linearly polarized glasses and circularly polarized glasses. Linearly polarized
glasses usually have one side processing horizontal images and the other side processing vertical
images. This technology does not allow you to tilt your head, because the images will bleed
together. Circularly polarized glasses process images that are superimposed on to the screen using
circular polarizing filters. Because the filters are circularly polarized, the viewer can tilt
their head either way. We can make an educated guess that the contact lenses will be using
circularly polarized technology. Contact lenses can rotate within a persons eye based on its
shape.
If these contact lenses do come out, they won’t work with the current lines of 3D
televisions. The current models require active 3D glasses that have electronics behind
them.
I believe the best use for these would be for computer monitors at work. Many people
at work spend hours in front of a monitor and 3D glasses may be uncomfortable wearing them for 8 hours at
a time. 3D contact lenses would be the perfect accessory for a work station that would allow you to
do work in 3D.
