One of the involuntary actions that we carry out without stress is the blinking of our eyes. This is something many people will be interested in, knowing the reason it is so and what the significance of blinking the eyes is.

The blinking of eyes is actually a vital action that should occur, and it has its way of helping us in having a good visual of things. Blinking of eyes usually happens suddenly and in less than a second, which makes it also serve its purpose very well. This very purpose is the prevention of impurities or unwanted substances from entering our eyes.

That moment when a substance, either big or small, is trying to find make its way into the eyes, the eyes suddenly blink to prevent the substance from entering the eyes. Also, it is important that our eye globes are kept wet to enable us to have a good sight. Hence, the blinking of our eyes spreads mucous secretions and oils on the eyes globe.

There are different reasons why the eyes blink. It is normal for us to blink our eyes because it is a reflex action, which means the body does it automatically. But in some cases, the eyes blink excessively, which indicates an underlying condition.

Every time we blink our eyes, the eyelids spread a mucosa secretion to the surface of the eye. This helps to prevent the eye from drying. Blinking also keeps them from damaging stimuli like light, dirt, and other foreign bodies.

Sometimes when we notice excessive blinking, it can be related to stress, fatigue, and anxiety. When the eye blinking continues even after rest, it is an indication that there is a condition occurring in the nervous system: Blepharospasm, a condition characterized by rapid uncontrolled blinking and uncontrolled eye closure.

Have you ever wondered why you will have the tendency to blink more whenever something gets in your eye? This is completely natural because whenever you blink, you are producing enough oil and mucous secretions on your eye so that it will stay moisturized.

You have to admit that you need to keep your eyes open for most of the activities that you are doing. Blinking is also something that you have to do to ensure that you will keep your eye safe from something that can possibly hurt your eye. For instance, if you would allow your eyes to become exposed to a lot of dust, you will start to get uncomfortable. Bright lights can also damage your eyes and blinking can counter it.

You may have experienced some dirt going into your eye. What is the first reaction of your eye? It usually closes in order to protect itself further, right? The eyelids are in charge of spreading a thin layer of oil over the eyes so that it can be protected further from too-bright light, dust and other particles that may enter the eye.

At the same time, eye-blinking will make sure that the eyes will not become too dry. Some people experience dry eyes because of stress. Allowing your eyes to blink naturally can help solve this problem. Just imagine how painful it would be if your eyelids cannot blink. It can be a problem for you.

Blinking is a protective reflex that happens automatically by your body in response to something that might be harmful to you. You don’t really even have to think about protective reflexes. Blinking is your body’s way of keeping your eyeballs from drying out because with each blink, a mixture of oils and mucous secretions clean and moisten your eyes.

Blinking also helps protect your eyes from such things as bright lights and foreign bodies like dust. Coughing and sneezing are two other examples of protective reflexes. These two reflexes help to clear your nose and airways of irritating stuff.
