According to later traditions, the right eye represented the sun and so is called the “Eye of Ra” while the left represented the moon and was known as the “eye of Horus” (although it was also associated with Thoth).

It happens when blood vessels in the conjunctiva, the thin outermost membrane surrounding your eyeball, become infected by bacteria or a virus. As a result, your eyes become pink or red, and inflamed. It can also result from allergies or exposure to chemicals, like chlorine, in swimming pools.
A bacterial eye infection may be the result of trauma, eye surgery, contact lens wear, immune deficiencies, or other diseases that result in bacterial growth. The two most common bacterial infections of the eye are conjunctivitis, commonly known as pink eye, and blepharitis, a chronic inflammation of the eyelids.
If a person has signs of an eye infection, they should contact a doctor. Severe symptoms, such as extreme pain or a sudden loss of vision, require emergency medical care. Likewise, if symptoms of a stye, blepharitis, or conjunctivitis fail to improve with home care, people should see a doctor.
Your doctor may prescribe an antibiotic, usually given topically as eye drops or ointment, for bacterial conjunctivitis. Antibiotics may help shorten the length of infection, reduce complications, and reduce the spread to others. Antibiotics may be necessary in the following cases: With discharge (pus)
Types of eye infections include conjunctivitis (“pink eye”), keratitis, stye (“hordeolum”), blepharitis, corneal ulcer, and uveitis. Symptoms and treatment will vary depending on the type of infection. Bacteria, viruses, or other agents can infect the eyes and can affect the cornea, conjunctiva, and eyelids.
Eye infection treatment depends on the type of infection and the cause. Viral infections usually go away on their own, and home remedies, such as ibuprofen, warm compresses and moisturizing eye drops, can help ease symptoms. But medical attention is sometimes needed.
Salt water, or saline, is one of the most effective home remedies for eye infections. Saline is similar to teardrops, which is your eye’s way of naturally cleansing itself. Salt also has antimicrobial properties. Because of this, it only stands to reason that saline can treat eye infections effectively.
Infection can spread to the brain (meningitis ) and spinal cord, or blood clots can form and spread from the veins around the eye to involve a large vein at the base of the brain (the cavernous sinus) and result in a serious disorder called cavernous sinus thrombosis.
Bacterial pink eye often appears redder than viral pink eye. While viral pink eye may cause your eyes to water, bacterial pink eye is often accompanied by green or yellow discharge. Viral pink eye also often begins with a cold, whereas bacterial pink eye is associated with respiratory infections.
Conjunctivitis is the most common eye infection. Most cases are viral and do not require antibiotic eye drops. Infectious keratitis is a cause of blindness.
The SARS-CoV-2 RNA has been detected in conjunctival secretions and tears in patients with COVID-19. A study carried out by Güemes-Villahoz showed that the presence of SARS-CoV-2 RNA in ocular secretions supports the suggestion that the eye is a possible route of infection.
Saltwater has the same properties as tears and is a natural antiseptic. Saltwater kills germs and may kill some of the bacteria in your eye. Using saltwater is one of the most common eye infection treatments.
As best as we can determine, the four best drugs to combat acute bacterial infection in adults are: bacitracin/polymyxin B/neomycin; tobramycin; 0.6% besifloxacin; and 1.5% levofloxacin.
Eye infections may cause the whites to turn pink, eyelids to swell, or a clear or greenish discharge from the tear ducts. Eye infection is a condition in which a virus, bacteria or any other microbial agents may infect the eye. This can cause itching around the eyes, or the eyes may turn pink.
Preventing the Spread of Conjunctivitis
Viral and bacterial conjunctivitis (pink eye) are very contagious. They can spread easily from person to person. You can greatly reduce the risk of getting conjunctivitis or spreading it to someone else by following some simple steps for good hygiene.
Several herbs have been traditionally used to treat eye inflammation. Examples include calendula, eyebright, chamomile, and comfrey.
High sugar levels can damage the retina’s blood vessels and result in the creation of abnormal new ones. When new blood vessels grow on the eye’s iris (the colored part of the eye), it can cause an increase in eye pressure and glaucoma.
The antimicrobial properties of honey can fight a bacterial eye infection, stop it from spreading, and reduce redness, and speed healing. An older study done in 2004 analyzed honey’s antimicrobial effects against different kinds of bacteria, and demonstrated how well it can work against conjunctivitis in particular.
In some cases, it can last for longer than two weeks, which is known as persistent infective conjunctivitis. If you have any unusual symptoms, such as severe pain, blurred vision or sensitivity to light, it may mean that you have a more serious condition.
Pink eye (conjunctivitis) is an inflammation or infection of the transparent membrane (conjunctiva) that lines your eyelid and covers the white part of your eyeball. When small blood vessels in the conjunctiva become inflamed, they’re more visible.
Complications are very rare, but severe cases of conjunctivitis can sometimes lead to scarring of the eye. Infectious conjunctivitis can spread to other parts of the body, which may trigger a more serious secondary infection such as meningitis.
Antibiotics specifically kill or stop the growth of bacteria, but they have no effect on viruses or fungi. Therefore, unless the eye infection is caused by bacteria, antibiotics will be useless.
Many cases of mild bacterial conjunctivitis clear up on their own, within a week or two and without any specific treatment. Cleaning the eyes throughout the day with water and a clean cloth or sterile pad, and using lubricating eye drops, also known as artificial tears, may help to relieve symptoms.
