Usage of when, while and as
I have searched for usage of when and while but I am still confused.
While I was watching TV, she came in.
When I was watching TV, she came in.
As I was watching TV, she came in.
I know sometimes they are not interchangeable for the same meaning, but I still cannot find any meaning difference between the three sentences. So I feel like they mean the same in the example sentences. What do you native English speakers think?
Thank you so much again and have a good day.
