Second Sight is a British television crime drama, principally written and created by Paula Milne, that first aired on BBC One on 9 January 2000. Originally broadcast as a single two-part pilot, before being followed by a series of three two-part stories, Second Sight follows DCI Ross Tanner (Clive Owen), a maverick cop who finds out that he has a rare disease, AZOOR, which is causing him to lose his sight. Tanner's boss, Superintendent Lawson (Thomas Wheatley), little suspects that the man he named to head the elite Specialist Elite Murder Unit is losing his sight. Tanner struggles to keep his condition a secret, but soon asks himself how long can he keep solving crimes that not even the fully sighted can fathom.

The series also follows Tanner's battles with his irrepressible Inspector, Catherine Tully (Claire Skinner), who urges him to tell the truth for the sake of his own health. Rebecca Egan also co-stars as Tanner's long-suffering wife, Marilyn; while Benjamin Smith appears as his son, Sam.

The complete series was later released on DVD on 24 July 2006 via 2|Entertain.
