According to this test I have mild deuteranomaly. (in my case that's consistent with what I know from "proper" testing anyway).
The company linked to above have something to sell me:

Of course, these glasses aren't cheap - and come in three "flavours", full dark tint sunglasses, lighter tint sunglasses which might be ok in bright indoors, and glasses for computer/screen use. The darkest tint are the most effective - apparently.
The problem I have with this is that I don't see my colour vision deficiency as a causing a particular "problem" which could be "fixed" this way.
I only became aware of it when I was about 20, the rata trees were in flower, people were saying "look at that - wow". Wow indeed - I knew they were just seeing things. I do have issues with sailing at night, distant green nav lights look white (no problem seeing red), but practically it's not a problem (though it could be in some rare circumstances). Dark tint "colour corrective" lenses don't seem to be a sensible solution for night navigation. I used to wear strange tie/shirt/suit colour combinations (not IMO - but most other people disagreed), but SWMBO had that sorted years ago, and she chooses paint/furnishing colours etc.
Traffic lights, electrical cables / colour coded components, normal day to day to day stuff don't cause me any issues at all.
My question is, if you were me, would you give these a try? It's piqued my interest - even though I don't know what I'm missing, I now feel that as there's a potential "cure" - I should do something. The makers claim that the glasses can offer a "profound emotional experience". My parsimonious nature ensures that spending $500 on a pair of sunglasses is already a profound emotional experience.
The price for one pair will mean paying GST / import fees, and probably return courier fees if I decided to send them back.
