We blink all the time and do it unconsciously most of the time. The average person blinks 15-20 times per minute or about 1,200 times per hour. But do you know why we blink?
Why Do We Blink
Blinking is not just for lubrication. It has incredible benefits for maintaining eye health and visual comfort. Blinking is the rapid closing and opening of the eyelids, typically occurring involuntarily every few seconds. A person blinks 15 to 20 times per minute, although this rate can vary depending on concentration, fatigue, and environmental conditions.
Protecting and Moisturising the Eyes
One primary function of blinking is to protect and moisturise the eyes. With each blink, our eyelids spread tears across the eyes’ surface, ensuring they remain moist and lubricated. This moisture helps prevent dryness and irritation, reducing the risk of discomfort and potential damage to the cornea.
Removing Foreign Particles
In addition to lubricating the eyes, blinking helps remove foreign particles and debris from the ocular surface. Dust, pollen, and other airborne irritants can accumulate on the eyes throughout the day. You know how you blink severely when something gets in your eye. The eyelids sweep these particles away by blinking, preventing them from causing irritation or injury.
Spreading Tears
Tears maintain our eye health by nourishing it, protecting against infection, and promoting clear vision. Blinking helps distribute tears evenly across the eyes, ensuring they reach all areas of the ocular surface. This distribution helps maintain a stable tear film for clear vision and eye comfort.
Preventing Digital Eye Strain
Many of us spend hours staring at screens, whether computers, smartphones, or televisions. Prolonged screen time can lead to a phenomenon known as computer vision syndrome or digital eye strain. When you blink regularly while using digital devices, it helps reduce eye strain by keeping the eyes moist and minimising dryness and irritation.
Promoting Relaxation
Beyond its physiological benefits, blinking also has a calming effect on the mind and body. Just as deep breathing can help induce relaxation, consciously slowing down and focusing on blinking can have a similar effect. Taking brief moments throughout the day to blink intentionally can help alleviate tension and promote overall well-being.
Blinking is more than a reflexive action; it’s fundamental to eye health and comfort. Understanding the importance of blinking and incorporating mindful practices into our daily routines can help keep our eyes healthy, comfortable, and vibrant. So, the next time you blink, take a moment to appreciate the invaluable role it plays in supporting your vision and well-being.
