I love MOL. I often search the internet to answer other people's questions. Yet I post first and let others search the internet to answer my questions.
Sound familiar taam, Case?

Yes, you can get sunburned through a window. There is no UV Filter in car or home glass (unless of course your windows have a UV film. |

No, you can't get sunburned through a window, unless it's made of quartz glass (or some other unusual substance) or you sit under it in full sun for days and days in a row (which is of course impossible).
Regular glass and even the stuff that most eyeglasses are made out of is basically opaque in most of the UV range. This website has a table showing UVA and B absorption by the materials in question. I believe that most eyeglasses (surely the shatterproof kind) are made of polycarbonate.
Case, your website is fine, except that it ignores that kids spend (or ought to) a huge amount of time outside in the sun, without the benefit of even auto-window glass.  . I'm much more concerned about their skin in full daylight (and little clothing, for example, at the pool), than mostly shaded and clothed in the back of my car.
An easy experiment: go lie outside at noon on a nice sunny day this week and leave both arms exposed. Cover one with a piece of glass. Compare the tan (or burn) on both arms afterward. If the piece of glass is small enough, use part of one arm instead. Or, for the less intrepid, leave a newspaper out in the sun for a shorter amount of time, covering part of it with a piece of glass. The visible light will damage newspaper too, so expect some yellowing overall. |
