That’s the minimum effective dose confirmed in multiple field trials with office and remote workers.\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e“Is it safe for my eyes?”\u003c\/td\u003e\n\u003ctd\u003eYes. It emits zero UV radiation, meets IEC 62471 photobiological safety standards for lamp emissions, and uses diffused optics to keep luminance below 10,000 cd\/m²—the threshold for discomfort glare.\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e“Can I use it while working at my laptop?”\u003c\/td\u003e\n\u003ctd\u003eAbsolutely. Position it slightly off-axis (e.g., left of your monitor) so light enters your peripheral vision—not directly in line with your gaze. This maintains circadian signal without screen reflection.\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e“How is this different from my desk lamp?”\u003c\/td\u003e\n\u003ctd\u003eMost desk lamps deliver 300–800 lux at reading distance. This delivers 10,000 lux at 12 inches—over 10× more photon flux per square centimeter, at a spectrum calibrated for non-visual photoreceptor response.\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e“Do I need to use it every day?”\u003c\/td\u003e\n\u003ctd\u003eFor best results during low-light months: yes, ideally at the same time each morning. Skipping more than 2 days in a row reduces cumulative circadian anchoring effect—like missing doses of a time-sensitive supplement.\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e“What if I have sensitive skin or migraines?”\u003c\/td\u003e\n\u003ctd\u003eThe light emits no UV and produces negligible heat (\u0026lt;32°C surface temp). If bright light triggers discomfort, start with 10 minutes and increase gradually—most users acclimate within 3 days.\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e“Does it plug into USB or need an outlet?”\u003c\/td\u003e\n\u003ctd\u003eIt includes a USB-C power adapter and works only with AC power (no battery). We prioritized stable, full-output performance over portability—because inconsistent brightness undermines efficacy.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003e30-day no-questions guarantee\u003c\/h3\u003e\n\u003cp\u003eIf you follow the included Light Timing Guide for 21 days (minimum 20 minutes within 1 hour of waking, at correct distance) and don’t notice objectively sharper focus by 10am or reduced morning drag on dark days—we’ll refund every penny.
