What Is Pink Eye and Stye?

Why Do People Confuse Pink Eye & Stye?

While pink eye and styes might seem alike initially, they can be pretty different in cause and symptoms. Pink eye, also known as conjunctivitis, occurs when the eyelid and eyeball’s transparent membrane becomes inflamed.

On the other hand, styes are red, painful lumps that pop up on your eyelid, resembling a pimple or a boil. They typically appear at the eyelid’s edge but can also develop on the inner eyelid.

And, they each have different causes.

Causes of Pink Eye

Pink eye has a few different variants, each with its own causes. The 3 types of conjunctivitis are:

• Infectious conjunctivitis is caused by exposure to bacteria or viruses, is highly contagious, and can spread easily to others without proper hygiene and care.
• Allergic conjunctivitis is caused by allergies such as pollen, dust, pet dander, or mould.
• Chemical conjunctivitis is caused by irritants such as air pollution, chemicals, or chlorine.

Causes of Stye

A stye occurs when bacteria, commonly staphylococcus, infect the oil glands in your eyelid. Several activities can increase your risk of developing styes by introducing bacteria to your eye. These activities include:

• Frequently rubbing your eyes with unwashed hands.
• Neglecting proper contact lens hygiene.
• Overwearing disposable contact lenses.
• Sleeping with makeup on.
• Using old or expired cosmetics.

Additionally, allergies and rosacea can both irritate the eyes and cause people to rub or itch the area, opening the possibility for infection. Other common issues that may increase your risk of developing styes include:

• Blepharitis (chronic inflammation along the edge of the eyelid).
• Meibomian gland dysfunction.

Pink Eye Symptoms

Pink eye, also known as conjunctivitis, is a common eye infection that affects the conjunctiva—the thin, transparent membrane that covers the white part of the eyes and the eyelids’ inner surface.

Symptoms of pink eye include:

• Eye redness or pinkness
• Itching or burning
• Irritation
• Watery or sticky discharge
• Eyelid swelling
• Light sensitivity

Treatment for pink eye depends on the cause. Bacterial conjunctivitis is typically treated with antibiotics, while viral conjunctivitis usually clears up on its own within a few days. A doctor might suggest antihistamines for allergic pink eye.

Stye Symptoms

A stye, medically known as a hordeolum, is a small, painful bump that appears on the edge of the eyelid. It occurs when the glands in the eyelid become blocked and infected, usually by bacteria. Styes can develop on the upper or lower eyelid and may occur multiple times.

There are 2 types of styes. External styes develop in an eyelash follicle and are more common. In contrast, internal styes begin in oil glands and can be much more uncomfortable as they push against the eye.

In addition to this swollen red lump, symptoms of a stye can include:

• Yellowish discharge
• Eyelid tenderness
• Sensitivity to light
• Grittiness
• Feeling like there’s something in the eye
• Excessive eye watering
• A crust around the eyelid

Treatment for a stye includes applying warm compresses several times a day to the affected eyelid. They could clear up on their own in about a week, but it’s crucial you don’t pop a stye, or it could spread the infection. In some cases, a doctor may prescribe antibiotics to treat the infection and reduce inflammation.
