Red eye in older adults

Overview

A red eye means the white part of your eye looks pink or red. It is usually not serious, but in older adults it can sometimes be a sign of a more serious problem that needs medical care.

Yes, red eye is very common in older adults. As we age, our eyes produce fewer tears and become more sensitive to irritation.

Red eye can affect anyone, but it is more common in people over 60 because of age-related changes in the eyes and a higher chance of other health conditions.

Symptoms

Common symptoms

• Redness in one or both eyes
• Mild discomfort or a gritty feeling
• Watery eyes or slight discharge

Symptoms in children

• This article focuses on older adults, but in children red eye is often caused by infections or allergies and usually clears up quickly.

Symptoms in older adults

• Redness that may be bright or dull
• Feeling of dryness or itching
• Burning sensation
• Mild blurring of vision that clears when you blink
• Sensitivity to light (photophobia)
• Discharge that can be clear or sticky

Causes

Main causes

• Dry eye syndrome – your eyes don't make enough tears or the tears evaporate too quickly.
• Conjunctivitis (pink eye) – infection or inflammation of the thin layer over the white of the eye. It can be viral, bacterial, or allergic.
• Blepharitis – inflammation of the eyelids, often causing red rims and crusty lashes.
• Subconjunctival hemorrhage – a broken blood vessel on the eye, often from coughing, sneezing, or straining. It looks alarming but is usually harmless.
• Corneal abrasion – a scratch on the clear front part of the eye, often from getting dust or sand in the eye.
• Uveitis – inflammation inside the eye, which can cause pain and light sensitivity.
• Acute glaucoma – a sudden increase in pressure inside the eye, requiring urgent care.

Risk factors

• Age over 60
• Long-term medical conditions such as diabetes, high blood pressure, or autoimmune disorders
• Wearing contact lenses (less common in older adults but still possible)
• Taking certain medications that dry the eyes (like antihistamines, diuretics, or some blood pressure medicines)
• Spending a lot of time in dry, windy, or dusty environments
• Smoking or exposure to smoke

When to see a doctor

See a doctor urgently if:

• If you have sudden vision loss or severe eye pain, call your local emergency number or go to an emergency department immediately.
• If your red eye comes with severe headache, nausea, or seeing colored halos around lights, seek urgent care same day.
• If you have had recent eye surgery or an eye injury and your eye becomes red, see a doctor right away.

Book a routine appointment if:

• If your eye is red but not painful and your vision is normal, you can try home care for a day or two. If it doesn't get better, see your doctor.
• If you have recurring red eyes or dry eye symptoms, talk to your doctor during a regular visit.

Diagnosis

A doctor or eye specialist (called an optometrist or ophthalmologist) can diagnose the cause of red eye with a simple exam. They will ask about your symptoms and look at your eye with a bright light and sometimes a special microscope called a slit lamp.

Tests that may be done

• Visual acuity test – you read a chart to check how well you see.
• Slit lamp exam – a microscope with a bright light to examine the front and inside of your eye.
• Tonometry – a quick test that blows a puff of air to measure the pressure inside your eye (to check for glaucoma).
• Swab – if the doctor thinks you have an infection, they may gently take a small sample of discharge for testing.

What to expect at your appointment

The exam is painless and usually takes about 15–20 minutes. Your doctor may need to put numbing drops in your eye to make the exam more comfortable. They will explain what they see and discuss next steps with you.

Treatment

Treatment depends on what is causing the red eye. Many cases can be managed with simple home care, while others may need medicine or a procedure. Your doctor will recommend the safest option for you based on your overall health.

Self-care at home

• Apply a cool or warm compress (clean cloth) gently over closed eyes for a few minutes to soothe irritation.
• Use artificial tears (over-the-counter lubricating eye drops) to relieve dryness. Choose preservative-free drops if you plan to use them often.
• Avoid rubbing your eyes, as this can make redness worse or cause more irritation.
• If you think an allergen is causing the redness, try avoiding the trigger (like dust, pollen, pet dander).
• Clean your eyelids gently with a warm, damp cloth if you have crustiness or blepharitis.

Medical treatments

If the cause is an infection, your doctor may prescribe antibiotic or antiviral eye drops or ointments. For allergic conjunctivitis, they may recommend antihistamine eye drops. For conditions like blepharitis or dry eye, they may suggest prescription eye drops that help reduce inflammation or increase tear production. For acute glaucoma or serious inflammation (uveitis), urgent treatment with eye drops or other medicines is needed to prevent vision loss.

When is surgery considered?

Surgery is rarely needed for red eye alone. However, if the redness is due to a serious condition like advanced glaucoma or a corneal injury that does not heal, a procedure might be necessary. Your doctor will explain if this is an option for your situation.

Living with this condition

Most people with red eye can continue normal activities, but you may need to rest your eyes more. If your job or hobbies involve dust, wind, or computer screens, take frequent breaks and use lubricating drops as needed.

Lifestyle tips

• Use a humidifier in your home to keep the air from getting too dry.
• Wear sunglasses outdoors to protect your eyes from wind and bright light.
• Clean your eyeglasses regularly (if you wear them) to avoid bringing irritants near your eyes.
• If you use contact lenses, switch to glasses until the redness clears (and always follow proper lens care).

Diet and exercise

A healthy diet rich in omega-3 fatty acids (found in fish, flaxseed, and walnuts) may help dry eyes. Stay hydrated by drinking enough water. Gentle exercise is fine, but avoid activities that could get dust or chemicals in your eyes, like gardening without safety glasses.

Mental health and emotional wellbeing

Having a red eye can be stressful, especially if you are worried about your vision. It can also affect your appearance. Talk to your doctor or a trusted person about your concerns. Most causes of red eye are temporary and treatable.

Prevention

You cannot prevent every cause of red eye, but you can lower your risk. Keep your eyes clean and protected. Avoid touching or rubbing your eyes. If you have dry eyes, using artificial tears regularly can help prevent irritation.

Vaccines

Vaccines do not directly prevent red eye, but staying up to date with vaccinations, such as the flu shot and COVID-19 vaccine, can reduce your risk of eye-related complications from viral infections.

Screening programmes

Regular eye exams are important for everyone over 60, even if your eyes seem fine. An eye exam can detect problems early, including conditions that might lead to red eye.

Complications

If left untreated

• Untreated infections can spread and damage the cornea (the clear front part of your eye), leading to scarring and vision loss.
• Untreated acute glaucoma can permanently damage the optic nerve and cause irreversible blindness.
• Chronic dry eye or inflammation can lead to discomfort and an increased risk of eye injuries.

Long-term outlook

The outlook for red eye in older adults is very good when you get the right care. Most causes are minor and clear up quickly with simple treatments. Even serious conditions, if caught early, can often be managed successfully to protect your vision. Your doctor will guide you through the best steps for your individual situation.
