I would really rather that these were actual examples, and not conspiracy theories. We all have our own unsubstantiated ideas about what shadowy no-gooders are doing, but I’d rather hear about things that are actually happening.
Disclaimer: Let me be clear, I’m definitely NOT defending the color blind glasses, and especially not the ridiculously expensive and over-priced, scam brand(s). Also, not going to watch videos on YouTube so my comment doesn’t take any context from those links. All that being said …
Sometimes people don’t realize that color blindness is a spectrum and that there are different types. For example, a lot of people like me might more accurately be described as color vision deficient. To me, I can clearly and easily differentiate between red and green in most practical circumstances, particularly in close range. Things can get dicey from a distance, as well as with very subtle tints or with very dark colors.
A number of years ago, I purchased a cheap (like less than $20USD) pair of fishing sunglasses (mirrored, polarized sunglasses that typically use bright red, orange, or green tinting of the lenses) right before taking a trip in the fall. When I put those sunglasses on, it was really surprising. All of a sudden I could differentiate between the trees that were dead or which had already dropped their leaves, versus those that were actually bright red. Normally, unless I’m looking at a specific tree from a close distance, the browns, reds, and grays all sort of look the same and blend in. From a distance, like from the top of a mountain looking down into a valley, the fall color change of the leaves is a bit underwhelming normally. With the glasses on, I could actually see individual trees or clusters of trees that were red.
To be clear, the cheap sunglasses didn’t restore my color vision. I assume it just shifts the spectrum a bit so that colors, which are normally very muted for me, actually stand out in the same way that bright yellows and blues do. And I know that the colors I’m seeing are tinted, so not 100% accurate to what a person with full color vision would see.
And when I’ve tested the fishing glasses with Ishihara tests (numbers in the colored dots), they do not improve my ability to make those out. So, that’s further evidence that they aren’t actually restoring my color vision. Granted, the fishing sunglasses never marketed themselves that way, where as the expensive scam color vision correcting glasses heavy imply that they are miraculous even if they don’t outright state that they restore color vision.
