Does the glass block lots of UV?
- sitkack 3y agoGlass blocks 100% of UVB and 25% of UVA. So while you wont burn, light through glass will still cause skin damage.

- urbandw311er 3y agoThanks - I learned something today. Looks like some bus companies treat their windows to block the UVA as well. Eg https://www.valleymetro.org/blog/2022/07/how-valley-metro-keeps-buses-cool https://www.valleymetro.org/blog/2022/07/how-valley-metro-ke...
- sitkack 3y agoWe need a little UVB everyday to maintain melanin (skin pigment) and skin thickness. If you work inside M-F and then go hard on the weekends outdoors, you will receive disproportionate damage from sunlight. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3427189/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3427189/ https://www.who.int/news-room/questions-and-answers/item/radiation-the-known-health-effects-of-ultraviolet-radiation https://www.who.int/news-room/questions-and-answers/item/rad... If you are blocking UVB, you should be blocking UVA as well. The bus folks are doing some good thinking.
