Come on there must be loads of you out there! What can you do when afflicted? I did see somewhere some little device that allows you to filter out either red a green light.

I've seen a little device that has two plastic filters, one red and one green. Holding those between you and the light is supposed to help you distinguish red from green.
The problem I find with distant lights is telling green from white.

About 8% of the male population suffer from colour blindness. It is very variable which is why filters don't always work. Like Portogeezer I have real difficulty in distinguishing green from white, but only re4d from green at distance. I have tried the filters and they are useless. I find ships OK as you can judge which way they are going from their steaming lights and I don't recall a situation where not being able to see the colour of the sidelights was a major problem- or at least I have got away with it up to now. Yachts and sectored lights are a different matter. I tend to make sure that someone in the crew has decent colour vision if I am sailing at night.

Same here, I have quite bad Red/Green and found that the SeaKey filter works quite well.
I also have been fine so far and usually have a good crew to help where needed. I do take extra care to understand what to expect before setting off on a passage, making notes of flashing sequences and distances of marks.
However when entering a very busy port like Las Palmas at night, even my two fully sighted crew couldnt make out the marks we needed against the busy backdrop of hotels, shops and car tail lights.
As a precaution I have AIS, Radar, and a good chart plotter to back up any sightings I make.
