Has your OH started losing his sight, Madcat, or has he always been partially sighted? My OH is totally blind yet still puts the washing in the machine, hangs it out and irons it later. He also does the hoovering (not perfectly but he does it) and can clean bathrooms if needs be. Oh and he doesn't let me fill the dishwasher as I don't do it the way he likes. His favourite thing, though, is operating the sound desk at church. He has also been my carer since I became disabled.
He's been blind all his life and his hand co-ordination isn't wonderful due to being born with hydrocephalus, but he gives things ago. He has driven cars to raise money for Guide Dogs and even had a go at towing a caravan off-road.
He amazes people with what he can manage but I'm used to it now.
Incidentally, his first wife - also blind from birth - bakes lovely cakes.
