black and white vision

[toolman]

Hi,

 

I heard the other day that when you exoerience something that makes you jump or when you need to react fast like walking out in front of a car, your vision goes into black and white mode. Is this true?

yes and no, it actualy stays in full color, but the brain filters that out as a way of only paying attention to the important details such as movement etc...

Are there such things as black and white glasses?

there are certain electronic goggles that will present an image in Black/white usualy for thermal imaging (night vision). more often they`re black and green though.
