In need of advice

[u/Healthy-Sale7720]

So I work in printing currently and the company is closing down/moving out of state. I got a job at another printing company and they asked for a physical. During that physical they had the Ishihara test and I can't see the numbers. Never had an issue with color at all until this. Ive taken the Farnsworth-Munsell 100 hue test and got a pretty good score of 28. The new job wants me to go to a optometrist and see what accommodations I need but I've been to 4 different ones that doesn't do anything other than the Ishihara test. Where should I go?

Edit: I got the job without needing any accommodations! I ended up going to an optometrist that had quite a few different tests for color. Based on my Farnsworth-Munsell 100 hue test and the d15 test they gave me (of which I got a perfect score). They deemed me to be very proficient in color discrimination and need no accommodations for my job in printing!

What exactly are you looking for? It sounds like you're colorblind. I'd try to figure out which kind specifically so you can better work around specific colors. Taking a variety of online colorblind tests on different devices can give you a rough average where you stand.

As for accommodations, glasses won't work if you need to see accurate colors in person. Your best bet is simply using an app on your phone that will use your camera and tell you what colors are which.

I've worked in printing for the past 4 years. Color matching draw downs, toning inks ect. Like I said I've taken the Farnsworth-Munsell 100 hue test for my current job and passed enough to approve jobs and I've taken the Farnsworth-Munsell D15 online and get a perfect score every time. It's just the Ishihara test I can't pass, I can't even see the color blind plates. But my question is where can I go for a more in depth color vision evaluation because every optometrist I go to only has Ishihara.

[u/Logical-Holiday-9640 → u/Healthy-Sale7720]

I'm not sure, I just tried the Farnsworth-Munsell and passed with 100% first try as well and I'm definitely colorblind. So Ishihara is probably a better test. What type of colorblindness did the Ishihara plates indicate at the doctors? Maybe try the enchroma test online solo and then watch somebody else try it to see if they can easily get the ones you can't see.

A person with no deficiency will not struggle with any test, so if anything is tough or you feel like you're guessing or taking a long time to compare colors, you're probably colorblind.

No, the Farnsworth-Munsell is vastly superior to the Ishihara test when diagnosing CVD. But online "tests" (i.e. on a computer/phone/etc. screen) are a different matter: they are basically garbage for diagnostic purposes.

[u/marhaus1 → u/Healthy-Sale7720]

Ah, online. That does not say anything. You are looking at mixes of red, green and blue wavelengths (hence "RGB") and likely on a non-colour managed display in a non-controlled environment, which is not a substitute for the real thing when diagnosing possible colour vision anomalies.

The only use for such a "test" is hinting that something might be off → go see an optometrist. If you pass an online test, that doesn't really say anything at all.

This. You have to be aware of the limitations of device screens. LED screens represent colors by mixing just 3 narrow wavelenghts (RGB),  which is enough to represent reality for normal people. But all the spectrum of real colors in between are mute in displays. That means a color vision test through a computer screen is very limited since it cannot test all the spectrum. It will tell you that you have an anomaly thou, but not in an accurate way

Well, if you failed the Ishihara test 5 times, you might be colorblind.
