Infrared is not visible
Infrared doesn't pass through windows.
actually thats UV. transition lenses won't change with a glass window thats not open. infrared is basically heat and does indeed pass through. Cars in the sun would not get hot so fast if they did not let in infrared.
Some UV is blocked by glass. Either UVA or UVB. It doesn't block both.
yeah I encountered it when looking at infrared for another convo in the thread. its uvb for what we think of as glass. the clear stuff. which is what causes sunburns and the transition lenses to activate.
