The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
these proteins in the eye the melanopsin proteins they're only sensitive to bright light so they're not sensitive to they're not going to get you know switched off from the light that comes from a campfire or stars in the sky or a moon but it takes about a thousand Lux of light to basically flip that switch that tells your brain that it's daytime

So, one interesting thing with melanopsin, it's very less sensitive to light. It's a very lousy photoreceptor. So that means you need a lot of light. For example, you may need almost 1000 lux of light to fully activate melanopsin. And then another interesting part of melanopsin is it integrates light over time. So that means it actually remembers how much light exposure you previously had.
