This is a dedicated lens hood for the Voigtlander 25mm f0.95 Nokton Micro Four Thirds lens. (Number 2 in the image)
Lens hoods are primarily designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. In addition, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact.
