Do sun ray tan through glass?
I live in California where the Sun is bright and warm. Everyday in the early hours of the day, I drive back from work.
The Sun then is right in front of my face. Yet my both arms are sun tanned.So my question is, do the sun rays work through the window shield of a car, or any other glass panel for that matter?
In other words, can people get brown through a window? By the way,I work at night and stay indoors for most part of the day light hours.

The glasses you wear usually have a special UV coating, just like camera lenses will have a UV coating. So that special coating is what blocks the Ultra Violet light from getting through the glass. They wouldn't need to manufacture that if glass naturally blocked it, and the Ultra Violet is what makes skin get tanned or burnt. That's why the UV index in the weather or the UV on the sun tan lotion. The glass could possibly make the light more focused or less focused so some of your arm could get more sun than the other end if you sit in the same spot for too long.

You cannot tan through glass. When the incoming short wave (Ultra Violet) radiation from the Sun hits the glass it is then converted to infra red heat energy and at this wave length your skin cannot tan. Your skin will just get warm as it absorbs this longer wave radiation.

Yes, through normal glass types. Not through special glasses like used in sun glasses.

JR is correct.
UV rays do not penetrate glass to produce any tanning of the skin.
