Do La Paz' cable cars have any UV protection on their windows, and if so, what's the protection?

    Can I ask the reason of your question? Travel are short, and cabins travel near soil, so with "frequent" stops (so use UV protection you use waling in the city). As i remember the cabins are new, with original windows (brownish), and not scratches [so good also for photography] – Giacomo Catenazzi Jan 6 '20 at 11:02
  • Either glass or plastic will do at least OK on UV protection. If doing anything else other than riding around in them, you would need your own protection (sun screen, shirt, sun glasses), so counting on the windows to protect you is asking a bit much. – Jon Custer Jan 6 '20 at 14:12
  • @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 weatheronline.co.uk/Bolivia/LaPaz/UVindex.htm – Franck Dernoncourt Jan 6 '20 at 15:52

    From ncbi.nlm.nih.gov/pubmed/19614895 - "Laminated glass totally blocked UVA radiation, while smooth ordinary glass transmitted the highest dose (74.3%)" - Since the glass is going to be some kind of safety glass (for, well, safety to prevent it from shattering in an accident), it is laminated. – Jon Custer Jan 6 '20 at 15:58

    @JonCuster Tempered glass may also be marketed as safety glass. Please see for instance wikipedia. One trivial example is the side windows on your car - they're tempered glass, whilst the wind screen is laminated. The reason laminated glass does not transmit UVA is the plastic component between the two panes of glass. – vidarlo Jan 6 '20 at 20:12
