How does visible light interact with your body?

    The primary mechanism for the absorption of visible light photons is the elevation of electrons to higher energy levels. There are many available states, so visible light is absorbed strongly by living things. With a strong light source, red light can be transmitted through the hand or a fold of skin, showing that the red end of the spectrum is not absorbed as strongly as the violet end. The violet side contains some serious problems for biologic tissues in excess.

    While exposure to visible light causes heating, it does not cause ionization with its risks. You may be heated by the sun through a car windshield, but you will not be sunburned - that is an effect of the higher frequency UV part of sunlight which is blocked by the glass of the windshield.

    So - question... can your skin collect the necessary UV signals while driving in a car first thing in the morning???

    is that because of the tint on the window, or does the glass bend the light??

    This is why glasses should not be worn in AM sunlight too if they are glass or plastic with UV protection

    A picture graph is worth a thousand words.
    note: there are different types of glasses, this is just the most seen.

    copy... that's what I was thinking... and why if I'm driving in the AM, I've got my window down, and arm out the window... But I've made a concerted effort to avoid commuting until after 10am...

    My glasses are off when I'm outside.
