The Day of the Triffids (1962)

The Day of the Triffids is a 1962 British film adaptation of the science fiction novel of the same name by John Wyndham. It was directed by Steve Sekely, and Howard Keel played the central character, Bill Masen.[1] The movie was filmed in colour with monaural sound and ran for 93 minutes.
A shower of meteorites produces a glow that blinds anyone that looks at it. As it was such a beautiful sight, most people were watching, and as a consequence, 99% of the population go blind. In the original novel, this chaos results in the escape of some Triffids: experimental plants that are capable of moving themselves around and attacking people. In the film version, however, the Triffids are not experimental plants. Instead they are space aliens whose spores have arrived in an earlier meteor shower Triffeds are strange fictional plants, capable of rudimentary animal-like behaviour: they are able to uproot themselves and walk, possess a deadly whip-like poisonous sting, and may even have the ability to communicate with each other. On screen they vaguely resemble gigantic asparagus shoots. Bill Masen (Howard Keel), a merchant navy officer, begins the story in hospital, with his eyes bandaged. He discovers that while he has been blindfolded due to an accident, an unusual meteor shower has blinded most people on Earth. Masen finds people in London struggling to stay alive in the face of their new, instantly-acquired affliction, some cooperating, some fighting: after just a few days society is collapsing. He rescues a school girl, Susan (Janina Faye), from a crashed train. They leave London and head for France. They find refuge at a chateau, but when it is attacked by sighted prisoners they are again forced to escape. Even though the Triffid population continues to grow. Meanwhile on a coastal island, Tom Goodwin (Kieron Moore) a flawed but gifted scientist, battles the plants as he searches for a way to beat them.  From Wikipedia,
