EVS-EN ISO 9241-391:2016

This part of ISO 9241 establishes guidelines for the reduction of photosensitive seizures, one of three major undesirable biomedical effects, induced by images presented on electronic visual displays. The guidelines address the conditions essentially produced by electronic visual image contents presented at home and in work environments, but not by electronic visual display. The guideline in the document is for the protection of the vulnerable section of the viewing population who are photosensitive, and who are therefore prone to seizures triggered by flickering lights and regular patterns, including certain types of repetitive images.
