Colour deficient vision in stalkers

Yup, When I look at evening in low light through my zeiss"s at a bush with left eye and then with right eye I have a strong difference in the colours that my brain is registering.
I did have an operation on a squint in my left eye when I was 6 which cured the squint but left me crosseyed in the right as the muscle was relaxed and I had always blamed that on the colour changes.
Hmmm.

I am also red green deficient but only find it noticaable in daylight and the light starts to go I find I have better low light / night vision than most to the point I virtually never use a torch except for looking for a deer.

I also find that the deer are much much easier to see in winter coat. The way people describe how vividly they see a Roe Buck in full summer coat standing tall in a meadow is the way that a roe doe in full winter coat sneeking though the wood stands out to me.
 
That is of intrest to me as my no 3 son is colour blind, he is a very good shot so I have to find out what he sees in low light.

Yep, red green colour blind.

Impossible for me to follow any kind of blood trail unless it is on snow! There may be gallons of it on the deck but I just cannot see it, hence I have to stalk with a dog. Likewise the bright red summer coat of a Roe buck is of no benefit to myself, looks pretty enough close up but just does not stand out against the lush greens of high summer.
 
I'm also red/green colour blind which makes it difficult to see deer when they are stationary so have to be very slow when stalking looking for the appropriate shape or movement. Blood trails are also a problem unless there is a lot of it.

Already, we are seeing examples of stalkers with colour vision diabilities here. On Wikipedia is the following interesting statement
'Color blindness is usually classed as a mild disability, but there are occasional circumstances where it can give an advantage. Some studies conclude that color blind people are better at penetrating certain color camouflages. Such findings may give an evolutionary reason for the high prevalence of red–green color blindness.[SUP]'

That begs the question are we stalker hunter gatherers actually a sub-set descended from ancestors that could see better through colour camouflages in battle and survived?! Cheers, K

K, a very interesting theory!
 
I'm red / green deficient in colour vision as are 7-10% of males!! http://en.wikipedia.org/wiki/Color_blindness#Management It's most noticeable in low light. Any readers got this male sex-linked genetic problem and has anyone found corrective coloured lenses to be useful? Yeah, seeing life 'through rose tinted spectacles' does come to mind! Cheers, K

I have trouble seeing browns in green, and difficulties in low light conditions, so I went to a specialist optician (specialising in shooting prescription glasses) who sorted me out with a pair of Zeiss shooting glasses with a yellow filter. See J.H.Steward (Bisley) Ltd | Shooting Sports Vision Opticians | Prescription Shooting Glasses for Clay, Game and Field Shooting | Call: 01275 838 532
 
Thanks Erik, I am currently testing various colour filters supplied to my home by these specialist opticians. Cheers, K
 
Colour Blindness

I also have colour blindness, I would prefer to say deficiency though.

I don't think camouflage has been used in battle for long enough to show up in evolutionary terms. Maybe seeing better in low light gave them an edge in hunting terms though.

I'm red/green & different darker shades colour blind too. Apart from entry to the RM I haven't felt it to be too much of a hinderence but would be interested in glasses to see what I'm missing. As an example (and I do not want or intend to start an answers sharing exercise here), I easily found 4 of the 5 spot the differences in a recent competition but could not for the life of me find the 5th. I was just about to chuck it in and handed it to the wife who immediately spotted it - colour.

Are you referring to the red/green scope objective, which I also didn't see but my wife did!
 
A very interesting read i am lucky that i am not colour blind but i can tell you a funny story. My pal an excellent shot is colour blind and when he was a young man went to buy a car that was in showroom condition and realy cheap in price. He test drove the car it drove like a dream so he thought got a great bargain here and bought it. When he got it home he enthused his new purchase to his friends that all fell about :rofl: :rofl: as his new pride and joy was Lady Penelopy PINK in colour.

Following on from my original thread, my optometrist referred me to a specialist who has a set of coloured lenses to see if any improved my red green perception. One by one these are used to cover the dominant and / or recessive eyes and the various Ishihara charts were re-examined. Results - magenta improved, violet & pink slight improvement, orange no change.
Next step is to test in the field against the quarry magenta contact lenses worn with my glasses to field test whether there is really an improvement. This is the cheap option and if it does improve red / green perception, I can decide whether to continue with them or order the much more expensive prescription magenta glasses.

There are two types of contact lenses available in the marketplace - Chromagen and Ultravision.

So, having never worn contact lenses before, this will be a first and I'll let you know how I get on. Cheers, K
 
I am not colour blind, but what some of you guys might find interesting, and might be able to understand better than

some one like me with normal vision.

For a long time deer were thought to be totally colour blind, and to only see in black and white, more recent studies suggest , their sight is more akin to what you guys see.
