Eyes picturize everything so we are able to see things as they are around us. And a very natural, involuntary action involved with eyes is blinking. We humans blink a lot throughout the day. To be very precise, in one minute we blink about times. This means we blink about times in an hour and about 28, times in a day. Funny and interesting , right? Well blinking is so important to protect our eyes.
Blinking is a very brief process, it lasts only a tenth of a second. But during this very brief time, blinking helps clear dust from the eyes. Even though we are unable to feel or see in the mirror, there are minute dust particles spread over the eye balls.
If these are not cleared then and there, our eyes could be damaged. And our vision could also be affected. The eyelids spread oil and other mucous secretions over the eyeballs and hence keep them from drying out. Apart from these two reasons, we also blink when we encounter any potential dangers for the eyes, like when dust or bright light hit the eyes. In addition, we blink to take a momentary rest — to our eyes, but more importantly to our brain. In this direction, even though blinking is kind of involuntary, we can see its association with many happenings.
For instance, when a person reads a book, he or she could be blinking at the end of each sentence. While there are some conditions that can cause you to blink more or less frequently, a change in your rate of blinking is rarely a sign of a serious issue. If you notice changes in your blinking and signs of an eye infection, neurological symptoms, or a recent eye injury, talk to your doctor. In this case, it may be a sign of a more serious condition.
