Reminds me of my younger years when I went to Daytona Beach for the first time.  Being from the northern latitudes I didn't understand what "direct rays" were and how to deal with them properly. I worked on a farm so I spent entire days in the sun - can't nobody tell me nothing!  We went out drinking the first night and since there was no way to sleep in Florida during the day in a tent, we woke up when it got hot (pretty much sunup) and we slept it off on the beach.  I sun-burned my eyelids so badly, they were sticking open between blinks. I never thought about the eyelids when I was applying the sunscreen.  Anyway, I went to a shop that sold skin products and they told me I had better use zinc oxide cream to keep the sun off them for the rest of the week... they had pink, yellow and blue.  I chose blue and thankfully only wore it by day.   Did I mention it was also the end of biker week when we arrived?  I didn't know there was such a thing.  I learned a lot on that trip.  Bikers don't seem to like people who are different even though they themselves are... uh, different.  The worst thing that happened was that one of them came up to me and said, in deep southern drawl, "What the fuck you got on your eyes, boy?"  I lost track of the number of times I had to say, "Zinc oxide cream.  I got a bad sunburn on my eyelids."
 Oh!  At night put this stuff on my eyelids.   It was expensive but so soothing.
