Don't forget to blink

Blinking is a reflexive action that our bodies perform automatically to keep our eyes moistened and protected. However, this simple reminder holds more significance, especially in today's digital age where screen time has dramatically increased due to the widespread use of computers, smartphones, and other digital devices.

Eye Health and Comfort

Blinking is essential for maintaining eye health and comfort. Each time we blink, our eyelids spread a cocktail of oils and mucous secretions (gross, but true) across the surface of the eye, which helps to keep it hydrated, clean, and protected from irritants and infections. When we don't blink enough, which can happen during prolonged periods of screen use, reading, or any activity that requires intense focus, our eyes can become dry and irritated. This condition is commonly referred to as Computer Vision Syndrome (CVS) or Digital Eye Strain, and symptoms can include dryness, redness, blurred vision, and discomfort.

Blink Rate and Screen Use

Research has shown that our blink rate significantly decreases when we're focused on screens, dropping from the average of about 15-20 blinks per minute to 5-7 blinks per minute. This reduction in blink rate can exacerbate eye strain and discomfort. Therefore, the advice "Don't forget to blink" is particularly pertinent for individuals spending extended periods in front of screens. It serves as a reminder to consciously blink more often to prevent dryness and irritation.

The 20-20-20 Rule

To mitigate the effects of reduced blinking and prolonged screen time, eye care professionals often recommend the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something 20 feet away. This practice not only encourages more frequent blinking but also helps relax the eye muscles by changing focus from near to far objects, reducing the risk of eye strain.

Blinking and Emotional Expression

Beyond its physiological benefits, blinking also plays a role in social communication and emotional expression. Blink rates can vary according to emotional states, and deliberate blinking can be used to punctuate speech, convey feelings, or signal understanding during conversations. In this context, "Don't forget to blink" might serve as a reminder of the importance of non-verbal cues in communication. Finally, focusing on blinking can be a form of mindfulness practice, similar to focusing on one's breath. Such mindfulness exercises can help reduce stress and anxiety, bringing a moment of pause and relaxation in a busy day.

Conclusion

While "Don't forget to blink" sounds like an unnecessary piece of advice due to the automatic nature of blinking, it underscores the importance of maintaining eye health and comfort, especially in environments or situations that lead to decreased blink rates. It also highlights the role of blinking in emotional expression and communication, as well as its potential as a mindfulness practice. In the digital era, where screen time is prevalent, this simple reminder can be a valuable tool for preserving both physical and mental well-being.
