It is getting pretty spooky how quickly science
fiction is approaching “science reality.”
Researchers at Ghent University in Belgium have
been able to produce a spherically curved LCD
unit which may find its way into a contact lens.
The LCD can handle projected images using
wireless connectivity.
The fundamental technology behind this concept
already existed to a certain extent, but the
researchers at the university’s Center of
Microsystems Technology have been able to take
it a step further and allow use of the whole
surface of the curved lens. “Now that we have
established the basic technology, we can start
working towards real applications, possibly
available in only a few years,” according to
Professor Herbert De Smet. That is an impressive,
if ambitious, prediction. However, at the rate that
technology has been advancing, we are not going
to contest that objective at all.
Some potential applications would be remarkably
simple, such as lenses that would adjust
pigmentation and serve as sunglasses. Other
applications might involve conveying text
messages or navigation instructions. The
possibilities do not stop there, this technology
may offer additional methods to correct certain
vision impairments by controlling light
transmission to the retina. Those that like to
influence their own mood may be able to adjust
coloration and choose to see the world through
rose-colored lenses.
For now, the technology is approaching clarity
that we might see on a computer monitor. Of
course the real trick is to make all that work,
provide means of power, wireless connectivity,
while assuring comfort and confidence for the
user so that he or she is not concerned about
putting all that in their eye in the first place.
Check out the video below. It is no wonder why
they chose to flash the dollar-sign throughout, if
they are able to achieve viable commercial
applications in “only a few years,” there will be a
lot of money counting going on for sure.
