Activities for my blind grandfather?

My grandfather is blind and getting quite bored at home in lock down. My grandma is always out in the garden, or cooking etc and I just want to try and find something for him to keep him occupied. Before going blind, he used to watch a lot of TV, play card games and read the paper. Before this lock down, we would take him out for lunch and coffee and always be over there keeping him company. My grandparents are Greek so are used to always having friends over for coffee and socialising a lot.
If anyone has any suggestions, it would be much appreciated!
Thank you!
