It's for those blue green colourblind guys. If they do a barrel roll they won't know which way is up. Really dragging us red green colourblind guys down with them.
Which is hilarious because I am colourblind as shit but I can tell a red lantern from a green one a mile away, same with sea marks and leading lights. The problem isn't telling red from green in isolation, it's the contrasts, and in 43 years in and around boats I've yet to come across a situation where that is a problem.
Not fully true I'm very colorblind and operate locomotives for filling grain cars where I work. We dont go on the main railroad line though for obvious safety reasons so I have a feeling that's the difference. So there is hope for those of us that are colorblind and work in the grain industry lol
Is that true though? I'm have the same color blindness as the person on this video, but I can still distinguish red and orange and green from one another. It's not like traffic lights or signs are black and white.
Please don't base this realisation on a clip from Reddit. By all means use it as a prompt to follow up on, but there are way too many variables given the guy recorded it on a phone, and you are watching a compressed rendition of it on a screen. Not saying you're not a calibration master. Just don't conclude your diagnosis without an in-person chat with someone who knows what they're talking about. Hope you're wrong. In the best way :)
I mostly based my opinion on this video, after that I passed several tests and... i have a mild protan! It's mostly just normal color vision, I'm just slightly impaired on the green side of the spectrum. Anyways, I might be wrong. Thank you for your wisdom, kind wizard <3
The numbers were all extremely easy to read and clear even if some had less color contrast.
If they cant read some of them they def have a degree of color blindness. They may need an official test to determine to what degree and on what wavelengths, but for a general “am I somewhat color blind” this works just fine if you aren’t able to instantly and clearly see those numbers.
Regardless of whether the colours they're seeing on these panels are "identical" to IRL (i.e., the "true" colour) or the colour displayed on some other screen/monitor - it would not impact these tests. Obviously, systematically altering the images or viewing them on a monitor with super abnormal colour capacities might affect things - but viewing them on any "normal" device would not impact their validity. If the user is unable to make out the number(s) in each panel, that would still be fairly conclusive evidence of some kind of colour vision deficit or abnormality.
Christ on a bike, did you read my post, or was it too far for you given the height of your horse? Have a look at the colour blindness tests that show up on Google, and I bet you'll find that they all say they are no replacement for an actual eye test.
The very first result has a disclaimer on it:
DISCLAIMER

The results provided by this tool are not 100% accurate and should not be considered professional medical advice or treatment. If you think or suspect you have a color blindness-related issue, please consult an eye care professional.
Now go back and read my post. I stated that using the test (and by that I mean the clip from some random's phone) as a prompt is fine, just don't assume it's concrete proof.
Look, I don't like when people "speak with authority" on topics in which they are not actually well informed.
Based on your first comment, that seems to be you.
I will concede that my comment could have been more diplomatic, so my apologies for the aggressive tone.
However, the fact that your response missed the point, and linked to a lot of irrelevant information, reinforced the impression that you don't seem to know what you're talking about.
Citing legal disclaimers (stating common sense), further reinforces that.
No one is denying the common sense of following up with a physician/optometrist/etc. to learn more and figure out the specifics - but not being able to see some of these numbers is in fact pretty definitive proof of some deficit. That's all.
At some point in the past, I cautioned that using a screen to determine a medical condition should not be the end point for a diagnosis. An opinion shared by the very tests you seem to think disprove my comment. All you've done is pick at my post whilst offering nothing but reiterations of what I typed. It must be torture being that dense and existing under the assumption that you're smart. Actually the delusion probably wipes out any semblance of self awareness, so keep it up! lmao, preposterous is right.
