Watched Return to the Pond by Gardner and the guy in the film, whatever, stated that in winter carp eye sight deteriorated.
I asked the question on YouTube and will ask here is that scientifically true?

My personally thought are that - Once the water temps get proper constant winter cold, I believe that to be true, vision may become a bit blurred/non functional.
TBH carp do not need their eyesight to feed, so as the water temperature drops, this could well be one of the first senses to 'minimise activity' as it were.
More to do with survival and reserving energy I think. Once spring temps warm things up normal vision is restored..
I also seem to remember reading or watching Dr.Fish that is Simon Scott
talking about carp functions in the cold, longer digestion, minimal eating, etc.

The colder the temperature, the slower the receptors at the back or the eye and the neurons passing the stimuli back to the brain will work.
Probably nothing to do with conserving energy per se, though that will also happen, though almost irrelevant compared to energy saved by reducing movement and digestion.
