I had a dermatologist say if you can see by daylight inside, you should be wearing sunscreen. I thought that was a bit extreme, but I started wearing sunscreen daily and did so for 25 years. I live in an extremely sunny place. I also started wearing sunglasses. I am older now and have perfect skin. I have no vision problems. People made fun of me for being so conscientious, but now I am glad I did.
