The "Angry Eyes" video experimented with segregating participants into blue-eyed and brown-eyed groups to demonstrate how forced segregation affected feelings and treatment. The brown-eyed group was disrespected and made to feel worthless by the person in charge, who showed special attention only to the blue-eyed people. This gave participants insight into the mental, physical, and emotional challenges faced by segregated groups in the past and encouraged them not to judge people based on differences.
