    the iris must absorb so much light, because it stays completely black when shining a light directly on it

    FYI Its not the Iris constricting it's the pupil the Iris is the colored party the pupil is the black that's the one that's constricting

    The pupil is a hole from the cornea to the retina and the iris tightens to decreases light intake to the retina and loosens to increase light intake to the retina. So, those wired looking layers of holes in the iris are a bunch of important micro muscles.

    1. Dan should be holding the end of the lens until it is in position so his fingers can block it from poking his eye.
    2. You can have permanent vision loss from looking into the sun even for only a few seconds (though this is probably not as bright it still made me cringe).
    3. You don't need such a bright light, nor do you need the light entering centrally for pupil constriction (would've saved Dan from much pain from looking straight into the light).
    4. 4:55 pupil constriction*
    5. Awesome footage!
