Re-Timer 3 vs VivaRays Sol Clip'N'Go 3-in-1

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.

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.

Screen-heavy workers who want daytime, evening and nighttime filtering on one frame and will actually swap the clip-ons as the day goes on.

You only want a red night pair for the last hour before bed, or you need a safety-rated or sports lens, since VivaRays says the Sol is not ANSI Z87+ certified.
