Blind woman, accident and blue flashes, drama or thriller movie

I’m looking for a movie. A young woman with a pixie cut hair wakes up in hospital with bandage over eyes, presumably after accident. When she removes the bandages, she discovers she cannot see. After returning home, she feels as though someone is trying to kill her. A distinctive feature of the film was that the protagonist saw blue flashes before her eyes and seemed to be suffering from headaches. The film ends with the woman regaining her sight after one of the flashes and spotting a man who is her partner or saviour, and she hugs him.

My friend watched it in the autumn of 1999–2001, not before or after that. The film could have been made in the 1960s to 1990s, but the whole thing was shot in rather gloomy, dark colours, which would suggest the 1970s or 1980s. Made in US probably, but it isn’t sure. Genre: rather drama or thriller movie.

Thank you in advance.
