Wondering if anyone actually knows (that is, not just guessing) why RP causes decreased contrast in one’s remaining central vision. I asked my retina doc and got an obviously BS answer that cones can’t distinguish contrast as well as rods. I am not a fan of doctors who don’t have the phrase “I don’t know” in their vocabulary. I also googled and came up with a zip. FYI, I’m asking only because I’m curious. With me, the lack of contrast has existed since probably around the time I was diagnosed, it has progressively gotten worse as my vision has deteriorated. In the distant past I was a biologist, and I just can’t figure out why retinal changes would cause this. Seems more like something that would be caused by problems with the lens or cornea
Wouldn’t the loss of retina function also have a reduction in color vision which would result in a loss of clarity of certain color wavelengths so eg you’d go from seeing a 32 color crayola spectrM to a 24, then 16, etc resulting in an increase in percieved contrast? Just spitballing here.
