What is scotopic sensitivity syndrome?
« on: 06/12/2007 21:01:47 »
someone asked me what this is all about today, and I had to confess that I hadn't a clue - they mentioned something about wearing coloured glasses to make text easier to read - can anyone help with this?

What is scotopic sensitivity syndrome?

Scotopic sensitivity syndrome is based on the theory that some individuals have hypersensitive photoreceptors, visual pathways, and/or brain systems that react inappropriately to physical energy (wavelengths). The scientific community widely accepts that energy is received by the retina's photoreceptors, initiating a biochemical process affecting the visual pathways and deep structures of the brain. A growing number of researchers are taking an interest in the view that inappropriate biochemical processing has the potential to cause physiological and/or visual perceptual problems. Many of these problems are grouped together under the label "scotopic sensitivity syndrome". --Rhonda Stone, Author, The Light Barrier, St. Martin's Press, 2002/Griffen, 2003

Who comes up with these long complicated names? Scientists are so modest arent they :P

Even Chris is asking questions whose
answers are Wikipediable!  :o

Stana,
you should look at this issue the other way round:
which new word-name fits this brand new discovery of yours?
Imagine to be the scientist who achieved this result first, and
has five seconds left to find a name...before others steal it!  ;D

Well, visual perception is divided into "scotopic" and "photopic" regimes. The former corresponds to perception at low light-levels (roughly corresponding to moonlight and darker) where the very sensitive (but not colour-discriminating) rod-receptors dominate vision, and the latter corresponds to vision at higher light levels where the less sensitive but colour-discriminating cone cells function. (There's also "mesoscopic" which is the overlap/middle-zone where both rods and cones contribute usefully to vision.)

In normal daytime light-levels, the rods (normally associated with night-time vision - scotopic sensitivity) saturate (it's too bright) and presumably the normal brain just ignores them.

I would hazard a guess -purely from the name- that this syndrome has something to do with the rod-sensors in affected individuals causing some kind of problem when exposed to brighter light...?  (So the name is probably quite informative/descriptive)
