After I started eating beef liver for my acne, I noticed a kind of peculiar side effect, especially around the first month I started. I could pass color blindness tests. I have taken the same test dozens and dozens of times before eating any liver, I always get diagnosed as a deutan (enchroma site). When I was eating liver, I would notice kind of a strange visual acuity around two or three hours after eating it. For various reasons I stopped eating liver for about a month, and when I started again I could not pass the color blindness test as consistently anymore. Before, I could pass it on any computer or any screen, any test too (I tried several different ones).
I looked into it some more, turns out the US army did research on vitamin A treating color blindness in pilots during WW2. One study says that the vitamin A had an effect, while others did not find any improvement. It seems to have been written off and forgotten about, but I believe the effect was real. Obviously, it is not just the vitamin A at play here, there is something else it is interacting with.
It has been almost a year, and occasionally after I eat beef liver I can pass the color blindness tests. I think this must be something to do with calcium metabolism, or the interaction between vitamin A and maybe vitamin D? Maybe magnesium? When I first noticed the effect, I think I was taking around 10k IU oral vit D too, which I have since stopped in favor of direct sunlight. Without the liver, I fail this test every single time. I have tried removing liver from diet and adding it back in. It is definitely a necessary piece of the puzzle. Has anyone else noticed something like this, alterations in vision due to vit A? It would be cool to cure color blindness, then I could finally get a pilot's license lol.
