UV filters were unavoidable during the days of film cameras. As films were sensitive to Ultra Violet radiation, they used to create a haze in the pictures. Using UV filters reduces the haze and improves picture contrast.

| UV or Haze Filter |
We do not see any perceivable difference when we mount a Clear UV Haze Filter in front of the lens as human eyes are not sensitive to ultra violet radiation. A uv filter passes all colours in the visual spectrum but blocks UV rays. This is a difference which UV filters have from other types of photographic filters. Most other photographic filters are named for the radiations they pass through. But a UV filter is named after the radiation they block.
So if UV filters does not improve the picture quality, why keep them, there is one major reason for doing so and it is lens protection. A UV filter could be used as a permanent attachment on the lens and they will not affect the picture clarity. It protects the front lens element from dust and scratches. Even if you accidentally happen to drop a lens, a filter could suffer breakage instead of your expensive lenses front element. One other advantage is that the front element in any lens requires frequent cleaning, and it causes deterioration of surface finish. If you use a UV filter in front of the lens, it the UV filter that gets cleaned frequently and when it is damaged, you could easily replace it with a new one. Certain lenses like the Canon L series range which have weather protection, requires the use of a UV filter to complete protection.
So it is better not to debate the advantages and disadvantages of this inexpensive but invaluable piece of gear have one installed in front of every good quality lens that you own, one day you will be thankful to yourselves for doing so.
