Eyelashes and Eyebrow Functions - Everything Worth Knowing

Introduction

Eyelashes and eyebrows enhance facial features and make people look unique. They also have other functions. Lashes and brows play a crucial role in protecting the eye. They act as the first line of defense. There is a functional reason why hair is present above and around the eyes.

What Is the Presence of Eyelashes For?

Eyelashes are groups of short hairs at the edge of the eyelid. They act as dust catchers and protect the eye from debris, which can result in eye infection or obstruct vision. Eyelashes are very sensitive and act as sensors for the objects that approach the eye, such as insects and other triggers. Eyelashes act as the first line of defense and protect the eyes from air-borne dust, irritants, etc. When the eye is open and when the eye is closed, they act as a barrier and protect the eyes.

What Are the Functions of Eyelashes?

For those people who have long and curled eyelashes, they act as a barrier between unwanted dust and irritants that can enter the eye. There is a presence of specialized nerve endings in the lashes, which transfer the sensory feedback to the brain regarding the movements of the eyelashes. This information triggers the eyes to blink, where the eyelashes protect the eyes from dust and irritants and prevent the eye from getting dry. While blinking, the tears get distributed across the eye, which clears the debris.

Eyelashes are very sensitive, similar to animal whiskers. When a person touches the tip of the lashes, they can sense it immediately. Many times a day, the lashes come in contact with debris in the air and immediately cause a blinking reflex.

What Is the Presence of Eyebrows For?

Most people think eyebrows are present to enhance a person's facial features, but they also have protective functions. Similar to eyelashes, even eyebrows protect the eye by preventing sweat, rain, or other substances from falling into the eyes. The eyebrows and eyelashes work together to keep the eye safe and provide clear vision. The eyebrows are usually angled; this helps to prevent sweat and other irritants from moving along the face into the eyes.

Is It Fine to Change the Shape of Eyebrows and Eyelashes?

It is very common for people to change the shape of their eyebrows through waxing or plucking. The eyebrows can be thickened by weaving in extensions or lengthening the eyelashes. Usually, these procedures are done to change the shape of the eyebrows or lengthen the eyelashes, but they only disturb their function if these procedures thin them out. In some cases, repeated eyelash extensions and improper care of them can result in the loss of eyelashes, impacting their function and efficacy.

Why Do People Blink Regularly?

Blinking the eye is necessary to maintain eye health and helps lubricate. On average, the person blinks about 10 to 20 times per minute. Blinking is a natural process that helps to clean and refresh the eyes. A thin layer of tear spreads across the cornea when a person blinks. This tear layer helps maintain the moisture in the eye, removes the dust and dirt in the eye, and maintains clear vision. Excess tears, dust, and debris are washed down the tear duct into the nasal passage. This is why a person gets a runny nose when they cry. Blinking less than normal is not okay as it interferes with eye cleaning. When a person is staring at a screen, they may blink less, up to three to five times per minute. Less blinking can result in dry eyes or eye strain in the long run.

Even though blinking is involuntary, it is better to remember to blink when a person is involved in intense visual activity. The person should take regular breaks while staring continuously at the screen.

What Are Some Conditions That Can Affect Eyelashes?

Eyelashes act as the first line of defense, and there is a high chance that they can get infected. Some of the conditions that affect the eyelashes are

• Trichiasis is when the eyelashes grow inwards into the eye.

• Style is a condition where a painful eyelid bump is formed due to bacterial infection of the oil gland or eyelash follicle.

• Blepharitis is an inflammation of the eyelid which results due to bacterial infection.

• Trichomegaly, where the eyelashes grow extra.

• Madarosis is a condition where the hair present in the eyelash or the eyebrow is lost.

• Distichiasis is where there are two rows of eyelashes.

• Epiblepharon is a condition where the eyelash rubs against the eye.

As these conditions cannot be prevented, keeping the area around the eye clean helps prevent eye infections. False eyelashes and eye extensions or tinting can irritate the area and result in infection.

What Is the Importance of Regular Eye Examinations?

If the person experiences any pain, swelling, redness, or irritation along the eyelid or lash line, then the person needs to consult the doctor. The person should also be careful regarding any reaction when using new contact lenses or eye drops or has undergone any esthetic procedure such as lash extension or tinting.

Is It Better Not to Do Any Cosmetic Procedure to the Eyelashes and Eyebrows?

The person should be careful while enhancing the eyelashes and eyebrows cosmetically. As long as the person does not overdo it with makeup, only a little extra care is required to stay healthy. If the person experiences any inflammation or hair loss problem, they should consult with the doctor.

Conclusion

Eyelashes and eyebrows are more than providing a feature to a person’s face; they are more important in protecting the eyes. They act as the first line of defense. Eyebrows and eyelashes protect the eye from dust, debris, and other conditions that can cause eye inflammation. Cosmetic procedures such as eyelash extension will not affect the function of eyebrows or eyelashes unless they thin the hair.
