So you say all this but I haven’t seen any science to show that putting a filter over your eyes has any, and I mean any, effect on the your brains transmogrification of light.
As for the rods overlapping or whatever, can you link to a single scientific article that shows this to be the actual cause of CVD?
It’s just that colourblindness can be triggered by medication or diseases. Both of which do not affect your rods and cones. Additionally, putting pressure on the optic nerve can also triggered CVD. Again, the eyes themselves are unaffected.
_There are two types of photoreceptors: rods and cones.
Rods help you see in low light and around your central field of view (your peripheral vision). They don’t help you see in color, only in black and white.
Cones are the part of the eye that lets you see colors. They also help you make out fine details and see in bright light._
Sorry I wrote rods once when i clearly meant cones. You are correct that rods do not detect color of course, thank you for noticing the error.
Here is a pretty nice article on CVD that explores a lot of the genetics. It even mentions the enchroma (not by name of course) in the management section:
Another strategy—the use of so-called ‘notch filters’ to artificially separate the effective peak sensitivities of the expressed X-chromosome-coded photopigments in red-green anomalous trichromats—has yet to be explored fully.
This might be an older article as i believe some research on notch filters has since been done. As far as I know, there is some limited evidence that they improve performance specifically in colour discrimination tasks. There’s usually no evidence that they improve overall colour perception.
Not all cases of CVD are of this kind either (although it’s the most common cause), if you have monochromacy, dichromacy, or generally anything other than anomalous trichromacy, these glasses will do nothing. There are even rare cases where the eye can see colour perfectly fine and the problem is in the brain, although this is usually classified as some sort of aphasia and is not strictly speaking colour blindness.

Lastly, and please look this up, but rods are not able to detect colour or detail (that would be the cones at the centre of the eye). They are triggered by motion: https://www.allaboutvision.com/eye-care/eye-anatomy/color-vision/
