The reason why we have to be aware of this is because light sources can be very distracting and can get in the way of the student directing their vision to what we're asking them to look at.

SARA: Light can also be our friend. We can use it to highlight visual targets and make them easier to see. Light itself, though, should not be considered a visual target alone.
