Contact lenses for MD
July 5, 2013
Researchers have created
contact lenses which, when paired
with special spectacles, bestow
telescopic vision on their wearers.
According to the BBC, the contact-lens-
and-spectacles combination
magnifies scene details by 2.8
times, while polarising filters in the
glasses allow wearers to switch
between normal and telescopic
vision, with the system having
been developed to help people
suffering age-related blindness,
especially macular degeneration.
Age-related macular degeneration
(MD) is one of the most common
forms of blindness and damages
the part of the eye, the macula,
that handles fine detail.
As this area degenerates, sufferers
lose the ability to recognise faces
and perform tasks, such as driving
and reading, that rely on picking up
visual details.
The researchers from UC San
Diego and Switzerland’s EPFL,
adapted a pair of Samsung glasses
produced for 3D TV sets which
create a 3D effect by alternately
blocking the right or left lens in
sync with the television picture.
