Bring Real Sunglasses or clip-on.
by MikeySoft
.My prescriptions glasses have "Transitions" lenses. You know, the ones that turn dark in the sun. That way, I don't have to worry about carrying second sunglasses or clip-ons.I never had a problem then them. However, there was a heat wave when I was in Luxor, something like 45C or well into the 100s F. My glasses were only getting slightly gray. They were not getting dark.First I felt there was something wrong with my glasses. Maybe they wore out. In a few days, after the tempture went down to the low 90s F, they worked again. So, for some reason, Transitions lenses don't work well in high tempture.So, it is a good idea to bring real glasses or clip-ons.Please rate my tips when you find then interesting or useful.
