P3D pulfrich effect

[Donna Keas <rondonna@xxxxxxxxxxxxx>]

Thanks for the information on where to aquaria pulfrich glasses. While
searching the web I ran across a web site that described how red and
cyan lenses are better for pulfrich effect than the one dark lens. Does
anyone have an opinion on this? The web page I refer to is -
http://www.3dglasses.com/3dtv.htm
The information on that page claims that the one dark lens causes eye
strain.  It is my opinion that the eyestrain most people experience from
the pulfrich effect they've seen on network TV is caused by the improper
use of motion direction. If the glasses are set up for let to right
screen motion, to allow scenes with right to left motion is ignorant,
but all of the productions I've seen make this mistake. How many of you
have seen the expensive glasses that claim they make any TV show appear
in 3-D?  I suspect this is another abuse of the effect by allowing
people to assume that it doesn't make any difference which direction the
subject matter is traveling.
One more question- What is the purpose of the light yellow colored lens
on the left in the pulfrich glasses? I've found that I get a better
appearing image simply by using a lens from sunglasses over one eye.  I
also get good results from making a small aperture with my thumb and
index finger.

Thanks for the ideas and input.
