A new study has found that spending long hours in front of computer screens can severely strain the eyes and raise the risk of developing Computer Vision Syndrome (CVS) — a condition characterized by eye fatigue, headaches, and blurred vision.

According to The Sun, extended screen use is now one of the leading causes of visual fatigue. Before the COVID-19 pandemic, about 50% of adults suffered from the condition. However, as remote work, online education, and digital communication became more common, the number rose to 78%, with a significant increase also observed among children.

Studies indicate that between 50% and 60% of children experienced symptoms of computer vision syndrome during the pandemic due to excessive screen exposure for learning and entertainment.

Common symptoms include:

Eye strain and dryness 👁️

Frequent headaches 💢

Difficulty focusing and blurred vision

Neck and shoulder pain caused by poor posture

Experts recommend adopting preventive measures, such as reducing screen time, taking short breaks every 20 minutes, adjusting lighting conditions, and maintaining proper posture. Using blue-light-filter glasses can also help protect against harmful screen glare.

Researchers emphasize that limiting exposure to digital screens remains the most effective way to protect eye health, as prolonged light emissions from devices can disrupt the coordination between the eyes and the brain, leading to chronic fatigue if left unmanaged.
