1. Revision 3Oct 4, 2026, 3:32 PMLiveAI-organised, reviewed

   Adds newer reviews (2026) that sharpen the picture: no clinically meaningful average reduction in short-term digital eye strain, small and inconsistent sleep effects with subjective improvements often not confirmed objectively, and no support for routine preventive use. Adds detail on filter spectrum, colour/contrast trade-offs, sparse adverse-event reporting, and melanopic filtering density as more relevant than label colour.
