The Science
Modern lighting and screens emit high levels of blue light, the same signal your brain uses to stay alert during the day.
When this light reaches your eyes at night, it can delay the release of melatonin - the hormone that tells your body it’s time to sleep.
Balterra’s Night (Amber) Lens is engineered to filter up to 95% of blue light between 380–500nm, including the wavelengths most responsible for suppressing melatonin.
By reducing this disruptive light spectrum, the lens helps your brain recognise evening conditions - supporting your body’s natural transition from day to night.
Unlike clear lenses or minimal coatings, our amber lens provides targeted biological filtration based on decades of chronobiology and optical science.
The result is a lens designed not just for comfort, but to support your natural circadian rhythm during evening screen use and indoor lighting.
