Might depend on the environment. I'm sure that those who park with their headlights facing the sun for a large % of the day will have it worse than others, but I'm also sure that some people repeat this protectant-necessity as more of an urban myth than truth.
It's not just the sun, headlight bulbs put out UV as well.
I've seen more than one headlight lens with a deteriorated circle about 2 1/2 inches across right on the hot spot of the bulb output.
Not Ex lights, something else.
