Pathway for Germs to the Eyes

Introduction

All people rub their eyes many times a day in different instances, such as when the eye is dry or tired, if the person is sleepy, or if the person thinks something has fallen inside the eye. During all these situations, the person tends to rub their eyes, which provides immediate relief from the symptoms. But rubbing the eye is a very dangerous act that can cause serious harm to the eye. When a person rubs the eye, they tend to transfer all the germs into the eye. Read the article to know more.

What Is Meant by Eye Infection?

Eye infection is a condition that affects the eyes and is caused by microorganisms like bacteria, fungi, or viruses. The most common form of eye infection is pink eye or conjunctivitis. Eye infections can occur in one or both eyes. Most eye infections are not serious and subside on their own, but some can result in vision loss, which requires immediate treatment. Eye infections can affect any part of the eyes.

Where Does the Germ Come From?

The germs are generally present all over the person's skin. These germs form an ecosystem called the skin flora. However, not all the germs on the skin harm the host. Some of these germs are beneficial and help prevent diseases and enhance the skin's immune system. Some of the germs and bacteria can also result in initiating some infections or diseases if they move across the skin barrier. For these germs, the eye is the easiest access point. These germs accumulate under the fingernails, multiplying and spreading to the body's surface.

Does Rubbing the Eyes Cause Germs to Enter the Eye?

People tend to rub their eyes multiple times a day without even thinking about it. They rub their eyes when they are tired or sleepy, when they are dry, or when they feel something has fallen into the eye. However, touching the eyes can make it easy for germs to enter. The hand is considered a breeding ground and a transportation method for bacteria.

How Can the Eyes Be Protected From the Germs?

The eyes are usually very vulnerable to bacteria and infection-causing viruses which are present on the skin. The eyelashes help prevent the entry of the irritant. Blinking is another advantage of the eye, as it coats the eye's surface with fresh tears each time. Apart from these, some steps need to be taken to protect the eyes from various infection-causing bacteria; these are

• Wash and clean hands regularly using soap and water. This is very important before placing or removing the contact lens.

• The nails need to be trimmed, as germs accumulate below the nail bud and are easily transferred when they come in contact with the eyes.

• Cleaning regularly touched surfaces such as doorknobs, switches, faucet handles, cell phones, keyboards, and remote controls.

• Wash regularly the things that come in contact with the face, such as towels, linens, and washcloths.

• The person should keep some items from others, such as makeup brushes, eye drops, or contact lenses.

• Wearing goggles and safety glasses when working in a hazard-prone area or with chemicals can protect the eye from external irritants and bacteria.

• The contact lens needs to be removed before sleeping.

Can the Eyes Protect Themselves From Infection?

Eyes, similar to other organs in the body, have their defense system. In the first place, the eyelashes help to keep the irritants and bacteria away from the eyes. So, each time one blinks, one tends to push the irritants away. The second defense mechanism of the eye is called the tear film. This is a thin fluid layer that helps to protect the cornea. This is done by maintaining a moist environment over the eye's surface. However, when the person rubs the eye, the cornea can get damaged, and the tear film can be broken, which acts as a passage for the bacteria to enter the eye.

What Are the Various Types of Eye Infections Caused By Germs?

Eye infection is caused when destructive fungi, bacteria, viruses, and microorganisms enter the eye when the person rubs the eye. Some of the common symptoms that eye infections can cause are:

• Blurred vision.

• Itching.

• Swelling.

• Pain.

• Sensitivity to light.

• Dryness.

These eye infection symptoms can be managed using prescribed eye drops, compresses, or ointments. Most eye infections subside on their own, but few require close attention. The eyes are the most sensitive part of the body, so it is better to consult the doctor if a person is experiencing any eye discomfort or infection.

What Can a Person Expect if They Have an Eye Infection?

Eye infections caused due to allergies are not contagious or dangerous to the eyesight. However, eye infections caused by bacteria, viruses, and fungi are contagious and can spread to other people. The affected person should avoid being around others until they treat the condition. Some eye infections, such as one that affects the cornea, are very dangerous to eye vision. So, an eye specialist needs to consult any form of eye infection. The doctors will help the person to know the causative factor and proper treatment options.

When Should a Person See the Doctor?

If the person has had an allergy before, they would be familiar with eye infections, but it is better to consult a doctor regarding any eye problem such as discomfort, pain, or discharge from the eyes. Immediate care should be given for eye injury, and in some cases of eye infection, immediate treatment should be given to prevent vision loss.

Conclusion

Eye infections are common and usually caused by bacteria, fungi, or viruses. These germs are usually present in the skin. They also accumulate under the nail bud and are easily transferred to the eye once the finger comes in contact with it. Most eye infections subside on their own, but few require immediate treatment as they can result in vision loss.
