It looks like Philip is enjoying the lights. But doctors don't know if he can see them at all.
A new type of therapy - called Lightscores - helps visually impaired children become more active.
Sensors are placed on different parts of his body. They trigger sounds as Philip moves. This helps his coordination and confidence. After just five minutes, he's much more adventurous.
