I started a new thread on this; you might want to check out some of the 
links I cited as they have equations that may be useful for blurred 
vision impairments.

 From googling for 'color blindness simulation equations' I unearthed 
the following references:

[1] http://steve.hollasch.net/cgindex/color/color-blind.html "Color 
Blindness Theory, Simulation"

[2] 
http://vision.psychol.cam.ac.uk/jdmollon/papers/Dichromat_simulation.pdf 
"Computerized simulation of color appearance
for dichromats"

I'm sure further googling will produce more reference materials.
