Many photographs use the UV filter as a lens protector and
therefore leave the filter in place almost permanently. A UV filter will not
protect the lens from rough handling but will help with general dust and
smears.
A filter is flat and can be removed for easy cleaning on
both sides. If the filter does get scratched either by dust or the act of
cleaning then a UV filter is much cheaper to replace.
