Blink is a 1993 American neo-noir thriller film directed by Michael Apted and written by Dana Stevens. Starring Madeleine Stowe and Aidan Quinn, the film follows Emma Brody, the recipient of a corneal transplant who works with a police detective to track down a serial killer whose latest murder she inadvertently bore witness to.

Plot

Emma Brody, a violinist for a Celtic rock band in Chicago, has been blind for twenty years as the result of an attack by her abusive mother. She volunteers for an experimental surgery where her doctor, Ryan Pierce, equips her with corneal transplants. Though Emma's vision is partially restored, a side effect is "retroactive hallucination", meaning some things she sees don’t actually register in her brain until days after first witnessing them.
