In today’s digital age, prolonged screen usage has become commonplace, leading to a significant reduction in our natural blink rate. This decrease can result in various eye-related issues, emphasizing the need to be conscious of our blinking habits.​

The Role of Blinking

Blinking is a reflex action essential for:​

Lubrication: Spreading tears evenly across the eye surface to keep it moist.​

Protection: Removing impurities and shielding the eyes from foreign particles, dust, and potential trauma.​

Typically, individuals blink between 15 to 17 times per minute. However, during activities like computer work or staring at electronic devices, this rate can unconsciously drop to five times or fewer per minute.

Impact of Reduced Blinking

When we blink less frequently:​

Dry Eye Syndrome: The tear film covering the eye’s surface evaporates without adequate replenishment, leading to dryness.​

Blurred Vision: Insufficient lubrication can cause intermittent blurriness.​

Eye Strain: Extended periods without blinking can result in discomfort and fatigue.​

These symptoms are collectively known as Computer Vision Syndrome (CVS) or digital eye strain. The rise in screen time, especially post-pandemic, has led to an increase in CVS cases, affecting productivity and overall well-being.

Preventive Measures

To mitigate the effects of reduced blinking:

Conscious Blinking: Make a deliberate effort to blink more frequently when using digital devices.​

20-20-20 Rule: Every 20 minutes, take a 20-second break and focus on an object 20 feet away. This practice relaxes the eye muscles and reduces strain.​

Use Artificial Tears: Regularly lubricate your eyes with appropriate eye drops, especially during extended screen sessions. Consult an eye care professional for recommendations.​

Optimize Workspace Ergonomics: Ensure proper lighting, maintain an appropriate distance from screens, and adjust screen brightness to comfortable levels.
