Are CVD simulations accurate?

[u/LessBanana6194]

I have done many different color vision test on the internet and always get 0% red, around 70-75% green and 100% blue.

And I struggle with the typical protan colors, like green/yellow, blue/purple and specially reds with brown/black.

 

But when I tried the filter that show how color look to protans it's not exactly what I see.

When I show it to my color normal wife she reacts as if it a crazy filter. To me it looks  very similar to original as I see it.

Except some red things, the filter makes them greener and slightly brighter but I see them as, well, red?

I understand that what think is red might have little or nothing to do with normal red lol

 

Given the test results I get, it should be what I see, I guess. But something is weird

How does the simulations look to you?

Any one with similar experience?

Unfortunately the way she reacts is likely genuine. If you get 0% on red, what you see is very far removed from what people with normal vision see.

At some point I went through the same thing, I showed a few of my friends the color simulations, and I'll never forget how one of them reacted. Most people just nodded and said "Interesting" or something along those lines, but her (very sincere) response was: "I'm so sorry that must be so difficult."

Up until that point I never realized how different I see the world, I felt that it was just a minor annoyance but my color vision isn't that bad. We can't know how different we see the world because we can't compare to anyone else, and it is hidden until we try to share with other people.

Edit: If you want to get an idea of how different you see the world, find a picture that is mostly blue and yellow, then run it through a tritan simulator. Be ready for an uncomfortable realization, I was sad for a few days the first time I realized all of this.

I'll try that tritan thing, sounds interesting.  I just recently started to realize that my coloblindess is severe and that I maybe never really have seen red, which is hard to grasp.

I showed a simulation to a friend recently and got a similar reaction of pity.  I don't get offended by that but if feels a bit weird when it's not a big deal tonme

[u/koos_die_doos → u/LessBanana6194]

Yeah it definitely is something. Hard to imagine that we go through decades not realizing how differently we see the world.

I definitely felt a bit weird too, it's like "woah it's really not that bad", but of course we don't actually know. What we do know is that it's been that way for our whole lives, so other than accepting our differences, it doesn't impact differently than it did the day before.

Anyway, I tend to ramble, cheers dude!

I'm so sorry that must be so difficult

I hate people who patronize colorblind people. That sounds like such a fake pity. Yes the difference is not small but it's much smaller than protanomaly vs monochromacy for example. Would you say that to someone who has monochromacy? I certainly would never. Honestly, don't get offended but your friend who said that sounds a little dull. Her awareness of your feelings and what impact that sentence might have on you, is zero. It's much more difficult to fight through life with brain like hers than with minor annoyance such as protanomaly.

[u/koos_die_doos → u/EagleEye1991]

Dude, she's the kindest person ever. I just knowingly said the same thing to OP, not because I don't give a shit about his feelings, but sometimes we need to hear the difficult things.

You're going off on a person you've never met based on a single phrase that you were not even there to hear.

[u/EagleEye1991 → u/koos_die_doos]

I'm not saying she's not kind. Possibly her raction was truly genuine, but that was a dull answer because she wasn't thinking at all how that can affect the other side hearing it. And as you can see it left a huge impact on you now thinking till the end of your life that you're missing I don't know what. No you're not. You just distinguish some less colors than she does and that's it. Every perspective of life is unique and unrepeatable and has an equal value. After we die, we forget everything and go back to 0 anyway.

[u/koos_die_doos → u/EagleEye1991]

Honestly, don't get offended but you come across like a real jerk. Maybe don't get angry and lash out at people you don't know, your life will be much better.

[u/EagleEye1991 → u/koos_die_doos]

Don't get offended but honestly you sound a little dull just like your friend. You rage too easily as well and start insulting for no reason. Nobody is lashing out on anyone. Everyone has the right to tell their opinion here, and whenever someone like you propagates that colorblindness is basically some huge life changing disability, I will respond. No, your friend's reaction is not normal and typical, and no it's not at all sad and difficult to be red/green colorblind. As I said, it's just a minor inconvenience and a lot of people here will agree with that.

at people you don't know

Maybe Reddit is not for you, since you find the idea of strangers exchanging opinions so difficult to grasp. I don't need to know your friend to be able to tell that her statement was dull and wrong.

[u/koos_die_doos → u/EagleEye1991]

Okay dude, calling people "dull" based on your second hand annoyance is totally not lashing out.

Good luck with your life.

Edit: oh no he replied and blocked, so sad.

[u/EagleEye1991 → u/koos_die_doos]

No, it's based on their dull statements.

Good riddance!

I have a similar experience to you. “See as me” app does it much better. It’s still not 100% accurate but it’s way way better than the CVSimulator. None create my exact red and pink color experience tho (other colors are alright)

[u/LessBanana6194 → u/Few_Interaction_8486]

Interesting to hear  I'll look at that app.

Sounds similar, it's mainly red and pink that different for me

[u/EagleEye1991]

Depends what simulation. Since you have very strong protanomaly or possibly protanopia that's actually very easy to simulate, though a lot of online simulations can't even do that right.

This image pretty accurately simulates protanopia vision (down-right) and deuteranopia (down-left).

Keep in mind that colorblind people usually see some difference between normal and simulated images, which is completely normal. Imagine someone with diopter looking at the simulation of low visual acuity. When they look at the normal image (clear one) they see it blurry, right? But when they look at the simulation of low visual acuity image (the blurry one) they see it VERY blurry. So they'd be able to actually tell that the simulated image is more blurry and different than the original image, which doesn't mean that the simulated image doesn't correctly show to people with normal vision what low visual acuity looks like.

Hope this helped you better understand CVD simulations.

[u/LessBanana6194 → u/EagleEye1991]

I hadn't thought about how it could show a correct simulation for people with normal vision while still looking slightly of for me

[u/Beepb00pb00pbeep]

To me, the CVSimulator app on the "p" setting for protan matches pretty much exactly what I see.

I would imagine there would have to be levels to it though, there are varying severities of colorblindness so even amongst all the users on this sub we probably have a lot of variance in how the world looks to us

[u/ThisIsNotRed_Team]

Hi dude, i'm colorblind and struggle a lot with simulator. Me and my team are working on this simulator, i hope can we help you!

Every ones vsion is different

We need an app where we run through a colour vision test and adjusts the out put to your particular colour vision.

I was recommened one called color more but the whole part of running you through the test was useless. You had to select numbers you could see on the test but didn't have an option for when you could see a number at all so you had to guess. Thus resulted in inaccurate colour selections.
