I use blue blockers but analyze: is blue light my actual problem? Map the light exposure: total light exposure matters more than just blue. Calculate: if I reduced ALL light in evening (not just blue), would that work better? Show me the light hierarchy: brightness matters more than color for most people. Give me the optimal approach: dim all lights vs. just blocking blue. Include: whether blue light is overhyped, what actually matters for circadian rhythm, and if I'm focusing on wrong variable.
