Final answer:

The bright lights of cell phones in a dark theater cause light pollution, interfering with the human eye's adaptation to low-light conditions. They also act as visual distractions, disrupting the viewing experience for others.

Explanation:

Cell phone lights in a darkened theater primarily cause an optical phenomenon referred to as light pollution. This happens as the bright lights interfere with the ability of the eyes to adapt to the low-light conditions of the theater. The sudden bright light can cause a sharp decrease in the ability to see clearly in a dark environment.

The bright screens also create visual distractions for other audience members. This is because human eyes naturally gravitate towards sources of light, especially in dark environments. As a result, cell phone lights can significantly affect the theater experience for others.
