DHAKA: People with careers that expose them to bright or or
artificial light, such as construction workers, fishermen,
welders or actors, could be pre-treated with infrared light to
reduce vision damage, say researchers. A team at Australia`s
Vision Centre has found that treating eyes with gentle infrared
light can help prevent the damage caused by subsequent exposure
to bright light. In their research, the researchers have shown
that pre-treatment with near infrared light prevents a build-up
of scar tissue in the retina causing subsequent harm to sight.
“There`s a group of cells that look after our vision and work
behind the scenes called Muller cells. They act to protect the
retina by clearing toxins and inducing healing whenever there is
injury to the vision cells. “However, their protection is a
double-edge sword for the eyes. When the retina comes under
extreme stress, as when it is exposed to intensely bright light
and loses a large number of vision cells, the Muller cells can
overreact by multiplying a
