Blue-light blocking glasses
Amber lenses worn in the evening: popular, and genuinely contested
Tinted glasses worn for a few hours before bed, to cut short-wavelength light from screens and overhead lighting. The evidence is mixed, and several researchers in this directory argue that overall light intensity matters far more than color, so dimming the room beats wearing the glasses. Included here because it is widely used and widely debated, not because it is settled.

Neuroscientist · Huberman Lab
Opening an AMA recorded at night under bright studio lights, he says he is wearing his ROKA red lens glasses, which cut blue and green light. His reasoning: bright light late in the day suppresses melatonin and raises cortisol, and the lenses offset part of that. ROKA sponsors the podcast, though this mention sits in his monologue rather than an ad break.

Biohacker · Bulletproof Coffee
Wears TrueDark glasses, from a company he founded, through every travel day: lighter lenses on daytime flights, full blocking lenses on evening ones so melatonin is not suppressed before landing. If you do one thing from his jet lag list, he says, make it this one.
