Calculate optimal TV viewing distance scientifically to protect vision and enhance viewing experience
Based on ophthalmology and imaging science standards
Based on ophthalmology research
Every 20 minutes of viewing, look at something 20 feet (about 6 meters) away for 20 seconds to effectively relieve eye strain
Children's eyes are not fully developed, viewing time should be strictly controlled and maintain a greater viewing distance
Recommend annual comprehensive vision checkups to detect and address vision problems in time
Consider using blue light blocking glasses or enabling eye protection mode on TV for prolonged viewing
Viewing distance calculation is based on human eye viewing angle and screen resolution. Standard viewing angle is 30-40 degrees. Higher resolution allows closer viewing distance. This calculator includes a vision protection coefficient, recommending distances slightly greater than standard values to better protect vision.
