How can you avoid visual fatigue when monitoring cctv?

To avoid visual fatigue when monitoring CCTV, ensure proper lighting and reduce glare on screens by using anti-glare filters. Implement regular breaks by following the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Adjust screen brightness and contrast to comfortable levels, and consider using ergonomic seating and monitor positioning to maintain a relaxed posture. Finally, incorporate regular eye exercises to help alleviate strain.
