Vue d'optique (French), vue perspective or perspective view refers to a genre of etching popular during the second half of the 18th century and into the 19th. 

Vues d'optique were specifically developed to provide the illusion of depth when viewed through a zograscope, also known as an "optical diagonal machine" or viewers with similar functions.
