Do La Paz' cable cars have any UV protection on their windows, and if so, what's the protection?
Answering some comments:
- @GiacomoCatenazzi: Travel can be easily over 30 minutes, and well over one hour if touring the city via cable cars. UV index in La Paz is often extreme https://www.weatheronline.co.uk/Bolivia/LaPaz/UVindex.htm
- @JonCuster: From https://thoughtco.com/does-glass-block-uv-light-608316:
Glass that is transparent to visible light absorbs nearly all UVB. About 75% of UVA passes through ordinary glass. UVA leads to skin damage and genetic mutations that can lead to cancer. Glass does not protect you from skin damage from the sun.
