Optogram

An optogram (from the Greek words opto- “light” and gram “record, image”) is an image obtained as a result of the residual glow of the light-sensitive cells of the retina after death.

When a person dies, the cells in the retina of his eyes retain a faint glow for some time, reflecting the last image he saw. This glow can be captured using special photography. This is how an optogram is obtained - the last “retinal image” of a deceased person.

Optographs are usually quite blurry and difficult to decipher. However, in some cases it was possible to discern the main features and details of the last thing the deceased saw. Optogram analysis sometimes helps investigators in investigating crimes and accidents.

Thus, an optogram is a unique post-mortem image that captures the last moments of a person’s life. Despite its vagueness, it can become an important clue in solving crimes and a puzzle for researchers.
