Pick the Manta Sleep Sleep Mask PRO if

Frequent travelers, anyone with light pollution, partners on different schedules, side-sleepers who hate flat masks pressing on their eyes.

Skip if

Pick the Re-Time Re-Timer 3 if

Frequent transcontinental travelers wanting to pre-shift before flights, shift workers, anyone with delayed sleep phase who can't fall asleep before 1-2am, light-deprived northern-latitude workers in winter, founders with chronically-shifted Monday-morning starts.

Skip if

You already use a 10,000-lux desk light box consistently and the desk-bound protocol fits your schedule. Or you have any photosensitive condition (migraine, retinal disease) - consult an ophthalmologist first.
