My mother-in-law has had macular degeneration for many years, she's 94 and lives alone.
Until recently she could get about and go into town on the bus. It's physical frailty that's put a stop to that though.
She can't recognise faces as the centre vision has gone.
She can't distinguish colours very easily.
She had a lot of gadgets through the RNIB and the local blind society to help her cope.
Orange buttons on the microwave for example so she can turn it to 1 or 5 minutes, orange buttons on the washing machine dial at the right programme.
A device to hang over the edge of a cup so she doesn't overfill it.
A hot water dispenser that she just puts a cup underneath to make a drink.
Lots in their catalogues to help your husband retain his independence.
My husband has organised a large-buttoned mobile phone for his mum with just a few pre-programmed numbers.
Most recently he bought her a Google Nest device (like Alexa) so that she can ask it for example to play the radio, what time it is, what the weather is outside.
She has a huge television screen and a flatbed scanner linked to it so she can read letters or the TV guide.
I bought her a 10x magnifying mirror as she still likes to wear makeup.
Best wishes to your husband and you Glenfinnan as he adjusts to this diagnosis.
