Fan, a 9th grader from San Diego, cites phototherapy as her favorite invention. She also says that it was the inspiration behind her headphones:

“Phototherapy has been overshadowed for decades due to the popularity and ease of use of antibiotics. Phototherapy is also commonly used for eczema and acne and is a non-medicinal way of killing bacteria and treating diseases. It is very versatile and has endless possibilities, and inspired me to start my project.” – Leanne FanThe Prevalence of Ear Infections in Kids
