Darkness-time is defined as the time interval from when you put on your virtual darkness eyewear to the time you want to wake up. It is of highest importance that you are not exposed to light sources containing blue light during darkness-time.
It only takes seconds of blue light to alert your brain and within less than five minutes your melatonin-level will return to zero. When going to the bathroom during darkness-time, Chrono Chrome's glasses should be worn. Alternatively, equip your bathroom with an adjustable light source not emitting blue light at night.
Warnings: Chrono Chrome's glasses are not to be used during the day. They should not be used when controlling vehicles or potentially dangerous machinery. Do not look directly at the sun or expose your eyes to extremely bright light when wearing Chrono Chrome's glasses. Chrono Chrome's glasses are not for children below 3 years of age. In case of serious illness consult your doctor before using Chrono Chrome's glasses.
Side effects, adverse events or injuries related to the use of Chrono Chrome's glasses should be reported to your doctor and firstname.lastname@example.org without delay.
