हम इतनी ज्यादा पलकें क्यों झपकाते हैं?

Why do we blink so much?

We blink frequently to keep our eyes moist, protect them from debris, and distribute tears evenly across the surface. This blinking action is a natural reflex that occurs involuntarily, controlled by the autonomic nervous system. Each blink spreads a thin layer of tears, which contain oils, mucus, and antibodies, across the surface of the eye. This moisture helps to keep the eyes lubricated, preventing them from drying out and maintaining clear vision. Additionally, blinking helps to remove any particles or foreign objects that may come into contact with the eyes, such as dust, pollen, or tiny insects. By blinking, we create a protective barrier that shields the eyes from potential harm and irritation. Furthermore, blinking plays a crucial role in maintaining visual comfort. It helps to prevent eye strain and fatigue, particularly during activities that require prolonged focus, such as reading or using digital screens. While the average person blinks around 15-20 times per minute, this rate can increase in response to factors like dry air, bright lights, or tiredness. Overall, blinking is a vital and often overlooked aspect of eye health, ensuring that our eyes remain moist, comfortable, and protected throughout the day.
