The German Society of Ophthalmology has identified Computer Vision Syndrome (CVS) as a medical condition affecting the eyes due to prolonged work in front of a computer screen.
Reduced Blinking Rate
This syndrome occurs because individuals often focus on coordinating movements with the cursor while working, which unconsciously reduces the blinking rate. This decreased blinking diminishes the supply of tear fluid that moisturises the eyes and gradually destabilises the tear film, leading to eye dryness.
Symptoms of Computer Vision Syndrome include burning and itching in the eyes, accompanied by headaches.
Tips for Managing Computer Vision Syndrome
To alleviate the symptoms, the society recommends taking short breaks to blink consciously or close the eyes for a few seconds, helping restore eye moisture.
The 20-20-20 Rule
Adopting the 20-20-20 rule can also be beneficial. Every 20 minutes, take your eyes off the screen and look at an object 20 feet away (approximately 6 metres) for 20 seconds. This allows the eye muscles, which are strained by prolonged near-focus, to relax briefly.
The room environment also plays a crucial role. Dry air from heaters can exacerbate the problem, so regular ventilation is recommended to maintain adequate humidity levels in the room.
