Here at Swanwick, we believe in science-based solutions. For this reason, we conduct extensive independent testing on our lenses to ensure the right levels of blue light are blocked for your specific needs. Swannies Blue Light Blocking Glasses are the most scientifically validated on the market. Night Swannies have been the subject of two separate independent studies, which both showed marked improvements in sleep factors and performance.
