What is going on with this article? It contradicts itself all over the place.
> All glass used in house, office and car windows completely blocks UVB from passing through.
But only laminated glass can completely block UVA. UVA can pass through other glass used in car, house and office windows and cause skin damage, increasing the risk of cancer.
Car windscreens block UVA, but the side and rear windows don’t
A car’s front windscreen lets in lots of sunshine and light. Luckily it blocks 98% of UVA radiation because it is made of two layers of laminated glass.

I fail to see the contradiction, such that I can’t even guess at what you think the contradiction might be. Could you clarify?

The article is horribly written. Get an LLM to summarize it in a table.
I just learned the the A and B refer to Aging (deep) and Burning (surface).

They don’t stand for that at all. You should reconsider your LLM use.
> Two types of UV light are proven to contribute to the risk for skin cancer:
> Ultraviolet A (UVA) has a longer wavelength. It is mainly associated with tanning and skin aging but can also lead to sunburn.
> Ultraviolet B (UVB) has a shorter wavelength. It is mainly associated with sunburn.

Yes but the letters don't stand for that. There is also UVC. We simply separated it into three ranges due to the different physical interactions and called it A B C.

Tinted windows may reduce incidence of skin cancer, but they are dangerous for pedestrians and cyclists because you can't tell if the driver is looking in your direction. If, for example, you are walking westbound on the sidewalk of a major boulevard on the south side of the boulevard and you need to cross a minor street at which a car with tinted windows is trying to make a right turn onto the boulevard, you need to be very careful!

I haven’t read the article. UVA and uvb are hardly blocked by pure glass. You can get films which let in almost all light and block almost all uv. 3M has a range.
