Regarding the eye sensitivity, is there any evidence on more vulnerable populations (people with dry eye syndrome or maybe people that have been operated for cataract?) there is no a priori reason they should be that much more sensitive, especially if the eye film isn't responsible for most of the protection anyway, but they are a significant minority of people.
Great summary, I learned a lot.
