    The eye only operates the iris based on the light intensity on what is around it, not what it is focused on. In this case, your looking at the side of the moon facing you, which is dark and the shadow cast on the Earth makes the enviroment you are in dark too so the iris is fairly dilated. While the sun is very bright around the mood during a partial eclipse, which burns it's image across the back of your retina.

    You shouden't really be looking directly at the sun anyway, ever.

    Minimum protection would be full face welding shield, even thats a bit weak.
