Protective Eyewear

CET’s recommended fitover and non-fitover eyewear to block short-wavelength blue light.

Night Light

Designed for children and for people who routinely get out of bed at night, the bulb produces an amber-colored light (removing the blue that is responsible for melatonin suppression) to allow the person to easily go back to sleep.

Microdose Melatonin

After years of lab research, we are introducing a novel melatonin formulation designed to sync the inner clock with sleep. It is not a sleeping pill. Rather, it mimics the action of natural pineal gland melatonin in the evening, hours before pineal gland activation, for people whose inner clock needs adjustment. To receive announcement of microdose melatonin availability, send us your contact information.
