Budgies (budgerigars / parakeets) are small, quick, and excellent at masking illness — but a budgie with an eye infection is usually visible enough for owners to catch early. In 2026, avian vets consistently note that eye problems in budgies are often linked to underlying respiratory infection or environmental irritants, which means treating just the eye without addressing the root cause often leads to recurrence.
What Does a Budgie Eye Infection Look Like?
Healthy budgie eyes are bright, clear, fully open, and alert. A budgie with an eye infection or inflammation may show:
- Watery or teary eyes — excess discharge around one or both eyes
- Crusty, sticky, or matted eyelids — dried discharge that clumps the feathers around the eye
- Swollen or puffy eyelids — tissue around the eye appears inflamed
- Half-closed or squinting eye — a budgie keeping one eye partially closed is in discomfort
- Rubbing the eye on a perch — trying to relieve irritation
- Redness around the eye rim
- Cloudy or hazy appearance to the eye itself
A budgie showing eye symptoms alongside not eating, fluffed feathers, or nasal discharge is likely dealing with a systemic infection, not just a localized eye problem.
Common Causes of Budgie Eye Infections
Conjunctivitis (Bacterial or Viral)
The most common eye condition in birds. Conjunctivitis is inflammation of the tissues lining the eyelids and eye surface, usually caused by bacteria such as Chlamydia psittaci, Mycoplasma, or E. coli, or by herpesvirus.
Chlamydiosis (formerly called psittacosis) is a significant cause of eye disease in budgies and other psittacines — it can also affect humans, making proper diagnosis especially important. Any budgie with persistent eye discharge alongside respiratory symptoms should be tested.
Respiratory Infection
Budgies' nasal passages and eye ducts are closely connected. Upper respiratory infections frequently involve eye discharge alongside nasal discharge, sneezing, and labored breathing. Treating only the eye while ignoring respiratory signs will not resolve the underlying infection.
Environmental Irritants
Cigarette smoke, aerosol sprays (cooking spray, air freshener, hairspray), non-stick cookware fumes (PTFE/Teflon), and dusty bedding are all common irritants that cause eye redness, tearing, and discharge in birds.
Trauma
A scratch from a cage wire, branch, or another bird can cause a corneal injury — presenting as a watery eye, squinting, and cloudiness. Corneal injuries need prompt avian vet care to prevent infection and vision loss.
Vitamin A Deficiency
Diets consisting mainly of seeds (without variety, fresh vegetables, or pellets) can lead to Vitamin A deficiency, which weakens the mucous membranes including those around the eyes. Swollen eyelids and eye discharge are common findings.
When to See an Avian Vet
Any eye symptom in a budgie should be evaluated by an avian vet promptly. Do not attempt to treat bird eye infections with home remedies or human or pet eye drops — these can cause serious harm. Contact an avian vet if your budgie shows:
- Any of the eye signs described above persisting more than 24 hours
- Eye symptoms alongside nasal discharge, sneezing, or labored breathing
- Reduced activity, sitting at the bottom of the cage, or not eating
- One eye significantly more affected than the other (suggests unilateral infection or injury)
- Any cloudiness in the eye itself (possible corneal involvement)
Treatment
An avian vet will typically:
- Examine both eyes and the nasal passages
- Perform a swab/culture to identify the causative organism
- Prescribe antibiotic or antiviral eye drops formulated for birds
- Treat any concurrent respiratory infection
- Recommend dietary improvements if Vitamin A deficiency is suspected
Most uncomplicated eye infections in budgies respond well to appropriate treatment within 1–2 weeks.

Frequently Asked Questions
Q: Can I treat my budgie's eye infection at home? A: No — do not use human or pet eye drops on budgies without avian vet guidance. Many active ingredients are toxic to birds. Always see an avian vet for proper diagnosis and bird-safe medication.
Q: Why does my budgie have one eye closed? A: A budgie keeping one eye closed or half-open is usually in discomfort — from an eye infection, corneal scratch, or trauma. This warrants a same-day call to an avian vet.
Q: Can a budgie eye infection spread to other birds? A: Yes — bacterial and viral eye infections, particularly chlamydiosis, can spread between birds in the same household. Isolate an affected bird and have all household birds tested if chlamydiosis is diagnosed.
Q: What home environment changes help prevent eye problems in budgies? A: Never use aerosol sprays, non-stick cookware, or cigarette smoke around budgies. Ensure the cage is cleaned regularly, ventilation is good, and the diet includes pellets and fresh vegetables alongside seeds.
