Blink - 1994

Emma is an attractive girl in her 20s who has been blind for 20 decades. A new kind of eye operation partially restores her sight, but she's having problems: sometimes she does not"remember" what she has seen until later. 1 night she's awakened by a commotion upstairs. She sees a figure. Convinced her neighbor has been murdered she approaches law enforcement, only to discover that she's unsure if it had been just her fresh eyes playing tricks on her behalf.
