Canon ET-65 III Lens Hood

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.

Dedicated lens hoods are designed to match the specific focal length of the lens it was designed for.

Lens hood offers several benefits to the photographer. Primarily the hood shades the lens from stray light that may result in an unwanted discoloration or hazing of the image, or the appearance of lens flare; shading your lens helps improve contrast and image quality. Also it offers limited protection from keeping moisture and wind blown debris off the from lens element and adds extra protection from accidental impact.
