Eye Flu

Conjunctivitis, also referred to as “eye flu,” is a common eye ailment that can afflict anyone at any age. The thin, transparent membrane that covers the whites of the eyes and the inner surface of the eyelids, known as the conjunctiva, becomes inflamed, which is how it is identified. Eye flu causes include viral or bacterial infections, allergies, and exposure to specific environmental irritants, among other things. Eye flu can be uncomfortable and irritating, but with the right care and treatment, the majority of cases clear up without any lasting effects.

Types Of Eye Flu

Flu in the eyes can take many different forms, each with unique causes and symptoms: 

• Viral Conjunctivitis

The most prevalent form of the flu in the eyes is viral conjunctivitis, which is primarily brought on by viruses, such as adenoviruses, which are also to blame for the ordinary cold or flu. Flu in the eyes is highly contagious and quickly disseminated by contacting surfaces that are infected with the virus or by respiratory droplets. Typically affecting both eyes, viral conjunctivitis can result in redness, irritation, watery discharge, and light sensitivity.

• Bacterial Conjunctivitis

Infections with germs like Staphylococcus aureus or Streptococcus pneumoniae lead to bacterial conjunctivitis. Poor hand hygiene, sharing contaminated objects, or touching the eyes with unclean hands can all lead to it. Symptoms of bacterial conjunctivitis, such as a thick, yellow or green discharge and crusting of the eyelids, might be more severe than those of viral conjunctivitis.

• Allergic Conjunctivitis

Allergy to allergens including pollen, pet dander, dust mites, or certain eye drops results in allergic conjunctivitis, which is not an infection. It usually affects both eyes and is a non-contagious form of the flu. The symptoms of allergic conjunctivitis include eyelid swelling, tears, redness, and itching.

• Chemical Conjunctivitis

When the conjunctiva comes into touch with irritants or chemicals like smoke, fumes, chlorine from swimming pools, or harsh cleaning products, chemical conjunctivitis develops. Although not contagious, this particular strain of the flu in the eyes can make your eyes red, itchy, and uncomfortable.

Causes Of Flu In Eyes

Conjunctivitis, also referred to as eye flu, is a disorder marked by inflammation of the conjunctiva, the thin, transparent layer that covers the whites of the eyes and the inside of the eyelids. There are many causes of eye flu, which result in ocular discomfort, redness, and inflammation. Understanding the origins of the eye flu is essential for ensuring prompt diagnosis and treatment. We will examine the main causes of eye flu as well as the contributing variables in this post.

• Viral Infections

One of the most typical causes of eye flu is viral conjunctivitis. Adenoviruses, the same viruses that cause the common cold and upper respiratory infections, are typically the main cause of viral conjunctivitis in cases of eye flu. Through contact with respiratory droplets from an infected individual or by touching surfaces contaminated with the virus and then touching the eyes, viral conjunctivitis can rapidly spread. This particular strain of flu in the eyes is extremely contagious and frequently affects both eyes at once.

• Bacterial Infections

The common condition known as bacterial conjunctivitis can also induce eye flu. This type of conjunctivitis is frequently caused by bacteria like Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae. By touching the eyes with dirty hands, sharing contaminated towels or eye makeup, or practising poor hand hygiene, germs can enter the eye and cause bacterial eye infections. One or both eyes may be affected by bacterial conjunctivitis, which might present with more severe symptoms than viral conjunctivitis.

• Allergies

An allergic reaction to allergens including pollen, pet dander, dust mites, mould spores, or certain eye drops can result in allergic conjunctivitis, a contagious but non-infectious version of the flu that affects the eyes. Here is the main eye flu cause for this type of allergy: The immune system releases histamines when the conjunctiva comes into touch with an allergen, which causes inflammation, redness, and stinging of the eyes. Allergy-related conjunctivitis often affects both eyes and is not contagious, in contrast to bacterial and viral conjunctivitis.

• Environmental Irritants

Because the conjunctiva is irritated, several environmental conditions might cause symptoms similar to the flu in the eyes. Conjunctivitis and discomfort may result from exposure to smoking, smog, harsh chemicals, and chlorine from swimming pools. Although these irritants can make the eyes red, itchy, and watery, they are not contagious and cannot be passed from one person to another.

• Contact Lens Wear

Wearers of contact lenses may also be more vulnerable to getting eye flu, particularly if they don’t practise good cleanliness. Conjunctivitis can be brought on by contaminated contact lenses or lens cases because they can infect the eyes with dangerous germs or viruses. To reduce the risk of eye infections, contact lens wearers must follow strict hygiene procedures that include appropriate lens cleaning, disinfection, and routine replacement.

• Newborn Conjunctivitis

The primary cause of newborn conjunctivitis, the eye bug, is frequently an infection contracted during delivery. Neonatal conjunctivitis, also known as ophthalmia neonatorum, necessitates urgent medical attention to avoid problems and safeguard the infant’s vision.

Symptoms Of Eye Flu

The symptoms of flu in the eyes can vary depending on the underlying reason. Some typical signs include:

• Redness and Irritation

Redness and irritation of the eyes are two of the main signs of the flu in the eyes. The blood vessels in the eyes enlarge due to conjunctival inflammation, creating the appearance of pink or red eyes. It’s possible for the eyes to feel scratchy, uncomfortable, or strange. In the mornings or after periods of rest, these redness and discomfort are frequently more apparent.

• Watery Eyes

Another typical symptom of the flu in the eyes is excessive tear production, which can result in watery or teary eyes. The inflammation of the conjunctiva, which can activate the tear glands and cause an overflow of tears, is the primary cause of watery eyes associated with the eye virus. Watery eyes can cause discomfort and blurry vision, which makes it difficult to carry out regular tasks.

• Sensitivity to Light

Photophobia, a disease where the eyes become sensitive to light, can occur in people who have the flu in their eyes. People may squint or cover their eyes from light sources as a result of eye pain and discomfort brought on by exposure to bright lights or sunlight.

• Discharge from the Eyes

A typical sign of bacterial conjunctivitis is a thick, sticky ocular discharge, especially in the morning. The discharge, which is frequently yellow or greenish, might make the eyelids adhere. Additionally, a watery or clear discharge from the eyes may be a symptom of viral conjunctivitis.

• Gritty Sensation

Some people who have the flu in their eyes could feel as though there is debris there because their eyes may feel gritty or sandy. It might be uncomfortable to experience this grittiness, which is frequently brought on by conjunctival irritation.

• Crusting of Eyelids

The discharge from the eyes in cases of bacterial conjunctivitis may dry and harden overnight, causing crusts to form around the eyelids. The existence of these crusts may make it difficult for people to open their eyes when they awaken.

• Swelling of Eyelids

When brought on by allergies, swelling of the eyelids may be a sign of eye flu. Eyelid oedema brought on by allergic conjunctivitis can give the appearance of puffy, enlarged eyes.

• Discomfort While Blinking

Due to conjunctival inflammation, those with eye flu may suffer discomfort or agony when blinking. Blinking may make the irritation worse and make you feel worse.

• Eye Discharge Contagiousness

Depending on the underlying reason, flu in the eyes can be communicable. Conjunctivitis caused by bacteria or viruses is extremely contagious and can be passed from one person to another through direct contact or inhalation of respiratory droplets. Contrarily, allergic conjunctivitis is not contagious and does not pass from person to person.

Conjunctivitis, commonly known as eye flu, is diagnosed by doing a complete eye examination as well as a thorough evaluation of the patient’s symptoms and medical background. Determining the underlying reason is essential for effective therapy because eye flu can be brought on by a variety of conditions, including viral or bacterial infections, allergies, or exposure to environmental irritants. In this post, we’ll look at how to diagnose eye flu and the possible tests to figure out what kind of conjunctivitis you have.

Conclusion:

Conjunctivitis, sometimes known as “eye flu,” is a common illness of the eyes that can be brought on by bacterial or viral infections, allergies, or irritants in the environment. It can be beneficial for people to adopt preventative actions and seek early medical assistance when necessary by being aware of the causes, symptoms, and available treatments.
