Trying to find the title of a black and white movie. I thought it was Citizen Kane but that is not it, just watched that one last night. The owner of a huge home (mansion) is blinded by a fire at his home and a previous love comes back to take care of him and he is not aware who she is nor ever finds out I believe. I thought Orson Wells played the leading man but not really sure. Movie is done with someone maybe a reporter telling the story.

It sounds like Jane Eyre, based on the Charlotte Bronte book. There are a lot of versions of this but there is one with Orson Welles.

Could be "Magnificent Obsession".
