What is the benefit of using a UV filter?
Why do many photographers leave UV filters on their lenses more-or-less permanently?

A UV(Haze) filter allows you to;
- prevents or attenuate a specific range of ultraviolet lights that pass into a camera to restrain haze and glare
- maintain image contrast and sharpness while reducing bluish color cast
- protect your camera lens from physical damages and many nuisances

A UV filter protects your delicate and expensive camera lens from dust, fingerprint, scratches, or, more importantly, from physical shock and damages.
It does, however, sound like the functions of another filter, Lens Protector, because a UV filter plays a role in lens protection and avoiding negative influences caused on images by Ultraviolet lights.
So what's the difference?
UV (Ultraviolet) radiation affects image quality in the form of haze, which impairs contrast and sharpness in the image.
UV filters are longpass filters that block & cut the UV wavelength range and transit the visual spectrum, the light we see in our eyes.
