Help needed with night vision

[heffkid]

I used to have a very simple device that helped to distinguish between red and green lights. It was a handheld device with one red and one green lens that you held up to the light in question and it would help define which it was. My problem is that it is missing and cant remember what it was called. I think it was a "seaky" but can't find it anywhere, I know I got it from an online chandlery but just can't remember where. I am lost without it can anyone help. Colour Blindness is a bitch!!

I'm just curious... If you're colour blind, how do you know which lens you're looking through?

I think these are for red/green lights in general, not just colour blind people. The lenses are different shapes, but I guess if you are CB you have to ask somebody once ...

Because you can see what colour the the lenses are

Its very easy to know the difference even if you were totally colour blind and see in shades of grey which is what some people believe that is what colour blind people see which is not the case at all,you just see colour in a slightly differnt shade that a "normal" person would see. Its like looking at everything with a tinted pair of glasses on, anyway to answer the question the red lens has rounded corners and the green has sharp corners so in total darkness you know. In any case i can tell what is the red and what is the green by looking at them but it is differnt when it comes to lights againts the dark back round it is one is brighter than the other but you can't tell what colour until you are very near them which can be to late!!
By the way and this might frighten some but I am an electrician and would fall a colour vision test but can tell the colours of the cables, these tests make no sense and this is a sore subject with many a colour blind person or to be corect a "colour vision deficiency".

The chap who used to live across the road from me, was also a "colour blind" electrician, and he had no problem with wire colours - although in his day, they were red and blue.

As for traffic lights, he just knew that the top was red and the bottom green.

He was not a sailor though.

I was Rediffusion's first colour blind colour television repair man

Although I totally failed the Ishihara tests at my interview, I demonstrated that I could read resistor colour codes perfectly well.
