Question for the red/ green color blind.

[fiasconva]

Mods, feel free to move this one but I have no idea which forum to put this question into. Those of you who are red/green color blind what do you see when you use an optic with a red or green dot? Does it make any difference or do they both just look grey? I obviously have too much time on my hands lately. *s*

I’m mildly color blind to red. I can see a red laser dot just fine in low light conditions. For some odd reason, I can’t pick up red when wearing polarized sunglasses.

I was hunting out west and thought my Leica rangefinder binoculars weren’t working. My brother tried them and he got a distance read-out just fine. The read-out is a red LED. I tried them again and didn’t see anything, until I took off my sunglasses.

I also have a hard time following a blood trail. Others can pick up the trail just fine from quite a ways away, but I struggle to see it up close.

I have the same problem with blood trails but generally because I have missed completely!

I want to know what you do at a traffic light? Brake or gas?

My three BIL's have red-green colorblindness but none are shooters. The reason all lights are in the same sequence top middle bottom is for people like them. Their great uncle trained himself to "see" wiring and wired sprinklers in large buildings for decades as a sprinkler fitter. He said they were all different shades of grey. Almost no research is done with this, glasses of some kind supposedly cure it but they were over $600 a pair with a 15-20% success rate last time they checked.

I see green better in the sunlight. Traffic lights are no problem. Most colorblind people have trouble with shades or when many colors are mixed say on a shirt.


Grass is green, sky is blue, blue jeans blue, firetrucks red.


Take the test! To a non color blind person these numbers will stand out perfectly!

Top light lit - Brake.
Bottom light lit - gas

middle light lit- Whatever you do on the yellow light.

I'm not color blind by the way.

I have red-green-brown color blindness. I’ve been fooling around with a red dot reflex sight in a pellet gun recently. No problem seeing the dot.

I also have astigmatism. Even lens corrected, this does distort the dot. Looks like a little off-centered starburst.

As for traffic lights, only issue I have is that at night green looks like a white light, so hard to tell difference between a green traffic light and a street light. Yellow and red stand out though, which is more important.

I also find that at times, pulling into a toll booth, perhaps dependent on sunlight, I have a hard time distinguishing between open booths and closed booths based on what I guess must be green or red lights. Fall back position, in such a case, is to ask the wife, if she’s with me, or follow another car.

Where it is a real problem though, is at night on the sea or in an airplane. Don’t want me in charge in those cases! The captain or the pilot needs to see the colors of lights in order to understand where he is and where other craft are in relation to him.

Calling color blindness being "blind" is really unfair. I learned this when I applied to become a state trooper and I took the Ishihara color "blind" test (which is now called a color vision deficiency test) and was told I was color "blind". Imagine my surprise, seeing as I painted cars and routinely spliced large bundles of milti-colored wiring together without incident.

Color vision deficiency is as diverse as regular vision and hearing impairment. Just because you can't hear some tones does not make you deaf.

Anyways..my color vision deficiency in red/green and brown/blues does not in any way affect my ability to use a red or green holographic site or lasers.

I see them all just as well,and have no preference to either. Green seems to be best for night,and red during the day but either works fine.

A friend drove during the Christmas holiday and asked me to verify the color of the stoplights as the Christmas lights made it hard for him to distinguish the stoplight color from a distance.
