The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
I wear sunglasses when I drive and whenever I need to throughout the day and I wear readers at night. I do not wear sunglasses when I get my morning sunlight, which I do every single morning as you should be doing also as is covered many times on this podcast.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

I wear Roa readers at night or Roa eyeglasses if I'm driving at night and I wear Roa sunglasses in the middle of the day anytime it's too bright for me to see clearly my eyes are somewhat sensitive so I need that I do not wear sunglasses in the morning when I'm getting my morning sunlight viewing for sake of setting my circadian rhythm but I do wear sunglasses often at other times throughout the day when it's very bright out
10 minutes of bright outdoor light within the first hour of waking anchors the circadian phase and improves sleep onset that night.
Morning sunlight exposure shifts the cortisol awakening response forward, improving daytime alertness.
Long-term morning sunlight reduces age-related macular degeneration risk.
Sleep regularity predicts all-cause mortality more strongly than sleep duration.
Tracking deep sleep on a wearable accurately reflects EEG-measured slow-wave sleep.
Caffeine has a half-life long enough that consumption after 2pm measurably degrades deep sleep in slow metabolizers.
