Blue light effects 

While any kind of light exposure at night suppresses the secretion of melatonin (sleeping hormone), blue light does so more powerfully.  Blue light is being translated by our brain as a daytime signal, so by being exposed to blue light at night we confuse our biological systems (Our brains want to sleep, but our bodies think it's daytime.) Most light sources (bulb, LED, lamp, digital device, and more) emit blue light today. Vaslav's mission is to produce light without suppressing our natural sleep process.

What is the circadian rhythm?

Circadian rhythm refers to our internal day-night clock. The clock tells our brain when it's time to get up and when it's time to go to sleep. Light exposure, especially blue light exposure, is one of the most important biological sensors for this clock. Vaslav was created to reduce the damage of blue light exposure at night on our circadian rhythms.

What is the "OCD dimmer"?

The "OCD dimmer" Is a dynamic switch that allows you to smoothly adjust the light volume.
