How Do Sleep (Previously Night) Swannies Reduce Evening Blue Light?

Sleep Swannies are designed to reduce blue light exposure in the evening through a combination of lens tint and anti reflective coatings.

The orange amber tint is calibrated to filter a significant portion of blue light within the 400 to 500nm range. This tint works together with anti reflective coatings to enhance overall filtration performance.

Research shows that exposure to blue enriched light in the evening may influence the body’s natural production of melatonin, the hormone involved in regulating the sleep wake cycle. By reducing these wavelengths before bedtime, Sleep Swannies are designed to support your body’s natural wind down process.

The lenses still allow other visible light to pass through, so you can move around your home, watch television, or use devices in the evening while reducing blue light exposure.

For best results, they are typically worn 1-2 hours before bedtime and kept on until lights and screens are turned off.
