Ever woken up with red, irritated eyes and wondered what’s causing it? What does it really mean when your eyes are red and swollen, and when should you worry?
Over-the-counter eye drops aren’t always the best answer to red eyes. Your eye redness could be a warning sign of something more serious, making it essential to seek timely advice. Not addressing the real causes potentially allows complicated conditions like uveitis to worsen, so it’s best to get your eyes checked by a professional health care provider.
I’m Juliet Menakaya, the owner and principal optometrist at Junic Eye Care. As someone with prescribing rights from the Australian College of Optometry, I’m here to offer insight and guidance so you can make informed decisions about your eye health.
In this article, let’s dive deeper into what might be causing your red eyes and how to address it.
3 KEY TAKEAWAYS
• Red eyes can be caused by common issues like allergies, but they can also signal more serious conditions like uveitis or glaucoma.
• Over-the-counter eye drops aren’t always a solution—proper diagnosis is key to preventing long-term damage.
• Early intervention is crucial in maintaining eye health and preventing conditions from worsening over time.
Minor Causes of Red Eyes
Why do your eyes suddenly look red or bloodshot? There are several reasons why this might happen, and while it’s not always reason for concern, you should know the potential causes.
Here are some common things that lead to red eyes:
- Allergies: Allergens like pollen, dust, or mold can trigger allergic reactions in the eyes, leading to redness, itchiness, and watering. This is often accompanied by sneezing or a runny nose. Over-the-counter antihistamine eye drops can help, but it’s wise to consult a professional to rule out any underlying issues.
- Dry Eyes: Insufficient tear production or rapid tear evaporation can result in dryness, often causing a gritty feeling, burning, and redness. This is particularly common in older adults and contact lens users.
- Eye Infections: Conjunctivitis, or pink eye, can be bacterial or viral. Bacterial conjunctivitis typically presents with yellow-green discharge and swollen eyelids. Viral conjunctivitis causes watery discharge and irritation and is highly contagious.
- Subconjunctival Hemorrhage: This occurs when small blood vessels break under the conjunctiva, creating a bright red patch on the white of the eye. It looks alarming but is generally harmless and resolves on its own within one or two weeks.
Always consult a healthcare professional if symptoms persist or worsen.
More Serious Conditions
While red eyes are often a minor issue, there are certain conditions that require urgent attention due to their potential to affect vision and eye health. Recognising more serious problems and seeking early treatment is a key step to prevent lasting damage.
Some of the more concerning causes of red eyes include:
- Uveitis: This inflammatory condition affects the uvea, the middle layer of the eye. It can lead to symptoms such as redness, blurred vision, and sensitivity to light. Uveitis can be chronic or acute, and without treatment, it may result in permanent vision damage or complications.
- Scleritis: Scleritis is a painful inflammation of the sclera, the white part of the eye. Unlike more common causes of red eyes, scleritis is often associated with autoimmune conditions, such as rheumatoid arthritis. The pain can be intense and worsens with eye movement, requiring prompt medical intervention to prevent further harm.
- Glaucoma: Glaucoma is caused by increased pressure inside the eye, which can damage the optic nerve over time. While many people associate glaucoma with gradual vision loss, red eyes, severe pain, and halos around lights are also warning signs. Left untreated, glaucoma can lead to irreversible blindness, making early detection and management critical.
- Fungal eye infections: While they are relatively rare compared to bacterial or viral infections, they can cause significant damage to the eye if not properly managed. Fungal infections usually occur after an injury involving organic material, such as getting plant matter or soil in the eye, and can lead to conditions like fungal keratitis, which affects the cornea.
- Herpes Simplex Virus (HSV): Infections from HSV can lead to herpes simplex keratitis which specifically affects the cornea, the clear, dome-shaped front surface of the eye. Symptoms, include pain, blurred vision, and light sensitivity. Herpes simplex keratitis requires targeted antiviral treatment and can lead to serious complications, including corneal scarring and vision loss if not treated properly.
If you experience persistent redness, pain, or any changes in your vision, it’s essential to seek professional care at once. Early action can help protect your eyes and preserve your sight for the future.
Treatment Options for Red Eyes
For milder cases, over-the-counter remedies can provide quick relief. Artificial tears are a great solution for dry eyes, helping to keep the surface of the eye lubricated. If redness is caused by minor irritation, a cold compress can help reduce inflammation and provide temporary comfort. Some people turn to decongestant eye drops, but it’s worth noting that they can actually make things worse if overused, leading to a condition called rebound redness.
Bacterial infections, like conjunctivitis, require antibiotic eye drops to clear up the infection. Viral conjunctivitis, especially when severe, may need antiviral medication or simply supportive care, as antibiotics are ineffective against viruses. For those suffering from allergic conjunctivitis, prescription antihistamines can offer more effective, long-term relief than over-the-counter options.
In more complex cases, steroid eye drops may be necessary. Conditions such as uveitis and scleritis, which involve significant inflammation, often require corticosteroids to manage the symptoms. However, long-term use of steroids needs careful management because it can have side effects, including increased eye pressure or cataract formation. These conditions should always be managed under the care of an optometrist to ensure the best outcomes.
Knowing which treatment option is right for you can save you from discomfort and prevent the situation from escalating. Don’t hesitate to seek professional advice when needed.

Prevention and Long-Term Eye Care
How can you keep red eyes at bay in the long run? While some causes of red eyes are unavoidable, taking steps to maintain good eye health can go a long way in preventing future issues.
Proper hygiene, especially if you wear contact lenses, is important. Ensuring your lenses are cleaned properly and replaced on time reduces the risk of infection. Avoid touching your eyes with unwashed hands, as this can introduce bacteria and viruses. Simple cleanliness habits can drastically reduce the likelihood of eye infections.
Eye protection is another important aspect of prevention. If you spend a lot of time outdoors, wearing wrap-around sunglasses can help shield your eyes from allergens, dust, and harsh sunlight. For those working in environments with high exposure to dust, chemicals, or other potential irritants, protective eyewear is essential in keeping your eyes safe from harm.
Making some environmental adjustments at home or work can also help prevent red eyes. If you live in a dry climate or spend long hours in air-conditioned spaces, using a humidifier can add moisture to the air, which helps prevent your eyes from drying out. Minimising exposure to common allergens like pollen, dust mites, or pet dander by keeping your home clean can also help.
When to See an Optometrist
When is it time to stop managing your red eyes on your own and consult a professional? While occasional redness may not always be a cause for concern, there are certain red flags that you should never ignore.
If you experience sudden, severe eye pain or a sudden loss of vision, it’s critical to seek immediate medical attention. These symptoms could be indicative of a serious condition like glaucoma or uveitis, which require prompt treatment to avoid permanent damage. Similarly, if the redness is accompanied by persistent discharge, sensitivity to light, or if it just doesn’t seem to improve after a few days, it’s best to book an appointment with your optometrist.
For those who have experienced recurring infections or flare-ups of chronic conditions like uveitis, regular eye exams are essential. The earlier we catch serious issues such as glaucoma, the better the outcomes, as early detection can prevent long-term damage. Even if your red eyes are linked to less serious causes, such as dry eyes or allergies, an eye exam can help us to tailor a treatment plan and provide long-term relief.
At Junic Eye Care, we use advanced diagnostic tools to get a detailed look at the health of your eyes. With therapeutic prescribing rights, we’re also able to provide the right medications for your specific condition, ensuring you receive comprehensive care.
Never wait until it’s too late. Prioritising regular eye check-ups can help detect issues early, giving you peace of mind and keeping your eyes healthy.
CONCLUSION
Red eyes can be caused by a variety of factors, including allergies, dry eyes, infections, and serious conditions like glaucoma, scleritis and uveitis. Common symptoms of red eyes include itching, burning, discharge, and sensitivity to light, all of which can indicate an underlying issue. While over-the-counter remedies might provide temporary relief, a professional diagnosis is best to ensure proper treatment.
Remember, leaving an eye infection unchecked can allow it to spread, making treatment more difficult and risking long-term damage. Your vision is too important to leave to chance—book an appointment today.
