In order to qualify for the trope, the cause of the blindness must be because the person is in the process of dying. Deaths caused as a side-effect of being blinded or being physically blinded by, say, having your eyes cut/stabbed out don't qualify. Also, the eyes shutting down as a result of multiple organ failures throughout the body count if said organ failure is the cause of death.
This is Truth in Television, albeit most examples exaggerate the trope for drama. If the character's death is Played for Laughs (intentionally or not), this may lead to Long-Lasting Last Words about being in the dark.
Subtrope of Five-Second Foreshadowing. Often accompanied by Blood from the Mouth. Compare I'm Cold... So Cold..., where it's the character's own temperature a signal that they're dying instead of their own visual sense. Contrast Death by Disfigurement, where the eyes are physically damaged, while this is just the body failing to the point where sight also failsnote , Go into the Light and My Life Flashed Before My Eyes. Not to be confused with Darkness Equals Death, where the scene getting dark indicates that something deadly is nearby.
