8 Possible Itch In One Eye Causes

The list below shows results from the use of our quiz by Buoy users who experienced itch in one eye. This list does not constitute medical advice and may not accurately represent what you have.

Inflamed eyelid (blepharitis)

Inflamed eyelid, or blepharitis, is a bacterial infection of the skin at the base of the eyelashes.

If the oil glands around the eyelashes become clogged, normal skin bacteria will multiply in the oil and cause infection. The glands can become blocked due to dandruff of the scalp and eyebrows; allergies to eye makeup or contact lens solution; or eyelash mites or lice.

Symptoms include red, swollen, painful eyelids; oily, dandruff-like flakes of skin at the base of the eyelashes; and eyelashes that grow abnormally or fall out.

If the symptoms do not clear with hygiene, see a medical provider. Blepharitis can become chronic and lead to infections of the eyelids and cornea; dry eyes which cannot take contact lenses; and scarring and deformity of the eyelids.

Diagnosis is made through physical examination of the eyelids, under magnification and through skin swab of the eyelashes.

Treatment includes warm compresses and careful washing of the eyelids; antibiotics in pill or cream form; steroid eyedrops; and treatment for any underlying condition such as dandruff or rosacea.

Rarity: Common

Top Symptoms: eye itch, sensitivity to light, eye redness, feeling of something in the eye, dry eyes

Symptoms that never occur with inflamed eyelid (blepharitis): severe eye pain

Urgency: Self-treatment

Chronically dry eyes

Chronically dry eyes are a relatively common condition, especially in older adults, that can be very uncomfortable and lead to damage of the surface of the eye. They are caused by a decrease in the tear production of the eye or an increase in tear evaporation. Risk factors inc...

Chronic allergies

Allergies are an overreaction by the immune system to something that does not bother most other people. Many people who have allergies are sensitive to pollen, but other things such as dust mites, animal dander, cockroaches, and mold can also cause a reaction.

Rarity: Common

Top Symptoms: fatigue, irritability, trouble sleeping, runny nose, congestion

Symptoms that never occur with chronic allergies: fever, yellow-green runny nose, chills, muscle aches

Urgency: Self-treatment

Bacterial conjunctivitis

Bacterial conjunctivitis, or pinkeye, is an inflammation of the clear membranes covering the eye. It causes redness, pain, and irritation of one or both eyes.

Staphylococcus or streptococcus bacteria are often involved, and anything that brings bacteria to the eye can cause conjunctivitis. Touching the eyes with unwashed hands; sharing eye makeup, washcloths, or towels; or improperly cleaning contact lenses are common causes. The same bacteria that cause the sexually transmitted diseases chlamydia and gonorrhea can also cause conjunctivitis.

Most susceptible are children, but anyone can be affected.

Symptoms include a gritty, burning feeling in the eye; discharge or tears; swelling; itching; pink discoloration due to dilated blood vessels; and sensitivity to light.

Diagnosis is made through patient history, physical examination, and careful eye examination. Smears may be taken from the eye for testing.

Treatment involves a course of antibiotic eyedrops. It is important to use all of the drops as prescribed, even when the infection seems to improve. Warm compresses over the eyes can help ease the discomfort.

Rarity: Common

Top Symptoms: sore throat, eye redness, eye itch, watery eye discharge, eye redness

Symptoms that always occur with bacterial conjunctivitis: eye redness

Urgency: Primary care doctor

New-onset seasonal allergies

New-onset seasonal allergies, also called adult-onset seasonal allergies, are sensitivities to pollen, mold, and other irritants that cause nasal congestion, runny nose, sneezing, itchy eyes, and sore throat.

Seasonal allergies commonly begin in childhood but can start at any age, especially among those with a family history. Moving to a different geographic location may trigger the allergy in someone with a genetic predisposition. Anyone with asthma is more likely to experience adult-onset seasonal allergies.

Sometimes the symptoms are actually from "pregnancy rhinitis" – nasal congestion and sneezing due to the effects of pregnancy hormones on the nasal tissue.

A new-onset allergy is often thought to be a cold, but a cold will clear up without treatment. Allergies persist, never getting better or worse, and can interfere with quality of life.

Diagnosis is made by an allergist, who will use skin tests and blood tests.

There is no cure for seasonal allergies but the symptoms can be managed for greater comfort and relief. Antihistamines, corticosteroid nasal sprays, and immunotherapy or "allergy shots" can be very effective.

Rarity: Common

Top Symptoms: sore throat, congestion, cough with dry or watery sputum, mucous dripping in the back of the throat, fatigue

Symptoms that never occur with new-onset seasonal allergies: fever, yellow-green runny nose, chills, muscle aches

Urgency: Self-treatment

Viral conjunctivitis

Viral conjunctivitis, or pinkeye, is an inflammation of the clear membranes covering the eye. It causes redness, pain, and irritation of one or both eyes.

The viral form of conjunctivitis is very contagious because it is caused by the same viruses that cause influenza or the common cold. It is spread when an infected person coughs or sneezes, and then someone else inhales the virus from the droplets in the air.

Symptoms include a gritty, burning feeling in the eye; discharge or tears; swelling; itching; pink discoloration due to dilated blood vessels; and sensitivity to light.

Diagnosis is made through patient history, physical examination, and careful eye examination. Smears may be taken from the eye for testing.

Antibiotics only work against bacteria and cannot help against a viral illness, and so antibiotic eyedrops are not effective against viral conjunctivitis. Treatment includes easing the symptoms with eyedrops and warm or cool compresses over the eyes until the illness has run its course, which takes two to three weeks.

Rarity: Common

Top Symptoms: eye redness, eye itch, sensitivity to light, feeling of something in the eye, watery eye discharge

Symptoms that always occur with viral conjunctivitis: eye redness

Urgency: Self-treatment

Irritated eye causing swelling

Chemosis is a sign of eye irritation. The outer surface of the eye can look like a blister, filled with water or fluid. It can occur from infection or allergies, or as in this case, from rubbing the eye.

Rarity: Ultra rare

Top Symptoms: swelling of the eye area, eye itch, eye redness, swollen whites of eyes

Symptoms that always occur with irritated eye causing swelling: swelling of the eye area

Urgency: Phone call or in-person visit

Contact lens-related eye infection

Millions of people wear contact lens daily without issue; however, there is a risk of infection. Often, infection is avoidable by keeping lenses clean.

Rarity: Rare

Top Symptoms: eye redness, wateriness in both eyes, sensitivity to light, constant eye redness, eye redness

Symptoms that always occur with contact lens-related eye infection: eye redness, constant eye redness

Urgency: In-person visit
