When stray light from the sun or any other bright light source hits your camera's front lens element at an angle, it can reflect off the interior glass surfaces. This causes flare which can degrade your picture quality. A lens hood can prevent this from happening.
The rigid design of the Canon Lens Hoods provides an added element of protection from impact damage to the lens.
Be sure the lens hood you select is the proper one for your lens.
