Why is longan called “dragon’s eye”?

Answer

The pale, translucent flesh cradles a dark, round seed.

The nickname "dragon's eye" stems directly from the visual appearance of the prepared fruit. When the easily peeled, thin, leathery shell is removed, the edible portion reveals a pale, translucent flesh surrounding a single, dark, round seed. This configuration strongly resembles an open eyeball, leading to the evocative name that suggests a watchful eye.
