Is this Retinitis Pigmentosa related?

Question

So I have Retinitis Pigmentosa (I have pretty much no night vision at all now)...and recently I've noticed that I sometimes have difficulties shifting my focus to things of different colors (in good lighting). If I'm looking at a light colored object, I have a hard time switching my focus to a dark colored object. For example, if I'm looking at a white wall and then try to look at a dark colored piece of paper with light writing on it, it takes me a good 3 to 5 seconds to adjust to the color change.

Could this be related to Retinitis Pigmentosa? Does it maybe have something to do with my poor night vision?

Answer 1

Both are signs of decreased dark adaptation.  At  night, your photoreceptors can't adapt to the darkness.  When going from  a light object to a dark one may have similar results and you notice a slowness to adapt.  So, the answer is yes.  It probably is related to the RP.
