I'm posting on behalf of my sister as she's being a computer numpty

She has been diagnosed with Acute Hydrops and is currently off work feeling very sorry for herself and light is causing her an awful lot of of pain. She's coming to see me in a week and I really wanted to take her shopping to cheer her up but I obviously don't want this to cause more pain.
So is it a good/bad idea for her to wear an eye patch given the state of her eye? Would that make things worse? Only thinking because of the light sensitive issue I though it might help.
Any thoughts/opinions welcome

Thanks
