A walking encyclopedia about light and how it influences the human brain, Joey Obermann explains how the quality of light affects quality of life. This electrical design engineer relates that light is something that affects our lives in ways that we can barely perceive, giving examples of how different kinds of light make us feel and act. Something we can all relate to these days is sitting in front of computer and mobile device screens. The eerie blue glow our technology tools create is similar to the light of dawn, so sitting in front of screens right before we go to bed is not good for our quality of sleep. He demonstrates how to change iPhone screens to an intensity more conducive to pre-sleep.

This talk was part of TEDxGreenville UNZIPPED, held April 11, 2014, at the Kroc Center in Greenville, South Carolina. For more information about Joey and his co-presenters, please visit .

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
