I'm pretty color-blind.... basically fail all except one or 2 of the color plate tests. Has anyone successfully received (or heard of anyone receiving) a 6-pack or Masters license while taking the vision tests with color correcting lenses ? I'm assuming these lenses would need to be on for all vision tests (color and acuity).

There is one testimonial for a US Pilot, and one testimonial for a mariner Capt's license obtained in Australia. Thinking I will pursue this if it's not a wild goose chase....

Thanks for any feedback !

I am quite curious about this as well. The best-hyped (and possibly justifiably) filtered lenses seem to come from Enchroma (http://enchroma.com/)

I will say that the technology explanation from Enchroma (filters that attenuate the intermediate colors : http://enchroma.com/technology/) seems more plausible than the explanation given by Colormax ("customized filters to change the wavelength of each color that goes into your eyes"), but I suppose the target customer is not generally technically literate so perhaps I shouldn't pay too much attention to this type of sales literature.

I don't need to get a 6-pack ticket, but I want to anyway, just for my ego. However, I have red-green color deficiency that is bad enough that I can't pass any of the accepted tests for the USCG ticket. I can pass tests that are used for firefighters and police, but these aren't good enough for the USCG. I've been considering trying the glasses, but I currently need progressive vision correction lenses, so testing the color-correction lenses would be an expensive non-necessity. Of course that seldom stops me, so perhaps I will...

Yeah, I do poorly on the Ishihara plates and utterly fail the FALANT, but my problem supposedly isn't typical red-green. If there were lenses compatible with my refractive requirements, i.e. progressives, I might go for them. My worst problem, however, is distinguishing faint green from while lights at night.

I didn't even know that I was color-deficient until I took an Ishihara test in High School. Once I discovered that, a lot of incidents from my earlier childhood now made sense: for example, cutting myself when opening a can of chocolate syrup and not realizing that was my blood dripping all over the floor, and me wondering why they would make the orange kapok lifejackets almost the exact same color as kelp.

About ten years ago I went to the Ophthalmology lab at U.C. Berkeley, and had them run a full battery of tests to see if I could pass any of them. Ishihara, Farnsworth Lantern, and one other that the USCG recognized were no-go for me. I passed the one where you sort a bunch of colored blocks (not USCG-approved). The Doctor in charge explained the exact type of color blindness I have, but I forget what he called it. He suggested that I wear red-tinted lenses for driving, because they would accentuate the red brake lights (so far this hasn't been a problem for me though). Dim white and green are also quite difficult for me, which makes ship and buoy light recognition a problem. At night I generally go by the white range light configuration. I can usually make out the colors using binocs -- I need area and brightness.

Yes, that does sound like bit of a problem. I also do better with whatever it is about binocs—the magnification or the light gathering—at night.

A colleague with red green colour blindness once ordered his new BMW colour on his own.

Never again, that car was so ugly he almost gave it away at trade in time.

But he thought it was British Racing Green, so he was happy for about a week.
