The design consists of a wearable-detachable waterproof red light and a protection cushion. The red light gives other swimmers in the pool a signal that a blind swimmer is approaching. When seeing the light, other swimmers automatically clear the line and give extra space for the blind swimmer. Additionally, since the blind swimmers cannot predict where the edge of the swimming pool is, or where the other people are, they are very likely hitting the wall or bumping into other people. To protect the blind swimmers, a floating cushion is designed to buffer the hit. At the same time, it serves as a secondary notice for other swimmers to keep their distance. In the worst-case scenario, other swimmers will not hurt the blind swimmers, but the impact is safely absorbed by the cushion.
