Vision Researchers,<br>
<br>
You are invited to join the Vision Technical Group for a
webinar on '<b>How Life on Planet Earth Has Adapted to
Environmental Light</b>' by Robert Fosbury. The event
takes place on <b>14 December 2022, 11-12 AM - Eastern
Time</b> (UTC - 05:00) via Zoom.<br>
Please register here: <a class="moz-txt-link-freetext"

<b>Robert Fosbury</b> is an astrophysicist who worked
nearly 30 years for the European Space Agency on the
Hubble Space Telescope project where he also participated
in early work on instrumentation for the James Webb Space
Telescope. Fosbury's research interests range from
exoplanets and stellar atmospheres to supermassive black
holes in radio galaxies and quasars and star formation in
the early Universe. Fosbury is currently an emeritus
astronomer at the European Southern Observatory - in
Munich and Chile. After retirement, he was invited to
become an honorary professor at the Institute of
Ophthalmology at UCL where he works in an
interdisciplinary team to study the interactions of light
with biology following a lifelong interest in mechanisms
of natural coloration.</font></font></p>
<p><font size="2"><font face="Helvetica, Arial, sans-serif">When
photosynthesizing life in the oceans started injecting its
waste product oxygen into the atmosphere over two billion
years ago, lifeforms had to adapt to what until then had
been a toxic gas. This was probably the time that the hazy
atmosphere of early Earth cleared to reveal the first blue
skies. Since then, both plants and animals have adapted to
the various forms of environmental sunlight which
influence both biochemistry and vision.<br>
<br>
Using recent work on the vision of reindeer during the
long arctic winter, Bob Fosbury will describe how these
animals turbocharge their eyesight to survive the extreme
and challenging conditions resulting from the effects of
the ozone layer which makes the extended twilight so blue.
He will conclude by remarking on how some recently
introduced forms of artificial lighting are breaking these
billions of years of adaptation and are beginning to
damage life of many kinds, including us.<br>
<br>
<b>What You Will Learn:</b><br>
• About environmental light and the role ozone plays,
particularly at sunrise or sunset<br>
• Reindeer vision and seasonal changes in their tapetum
lucideum<br>
<br>
<b>Who Should Attend:</b><br>
• Graduate students and researchers in vision sciences,
biology, optics, and ophthalmology<br>
• Optical researchers and professionals who would like to
gain insight into how animal vision adapted to best meet
the challenges in the visual environment, which might
inspire sophisticated artificial designs.</font></font></p>
