When a simple eye infection isn’t simple

Elton John recently shared that he has lost vision in his right eye after a severe eye infection while holidaying in France. His left eye has also been affected, reducing his ability to read, watch screens, or clearly see the people around him for more than a year.

No clinical details have been released, so the exact diagnosis is unknown. What is clear is that an eye infection, something many people assume will clear on its own, caused permanent damage.

Even with excellent healthcare access, eye infections can move quickly and leave lasting consequences. Redness, pain, sudden blur, light sensitivity, vision loss, or discharge should always be taken seriously.
Early assessment provides the best chance of protecting sight.

Would you recognise the early signs of a serious eye infection?

Your heart health and your eye health are more connected than you might think

One of the things I often explain to patients is that the eyes don’t work in isolation. They are closely connected to the rest of the body, especially the heart and blood vessels.

The small blood vessels inside the eye are very sensitive to changes in circulation. Because of this, the eyes can sometimes show early signs of health changes happening elsewhere in the body.

A recent study from UCLA Health found that people with higher cardiovascular risk were more likely to develop certain eye conditions later on, including macular degeneration, diabetic retinopathy, glaucoma and other retinal problems.

Factors such as high blood pressure, cholesterol, diabetes and smoking don’t only affect the heart. Over time, they can also influence how well the delicate structures inside the eye remain healthy. The important part is that many of these changes begin quietly, often years before vision is affected. This is why regular eye examinations are so important, especially if you have cardiovascular risk factors or a family history of eye disease. Early detection allows us to monitor changes and act before they begin to affect sight.

Do you think about your eye health as part of your overall health?

Something interesting about eye health I came across recently.

A large study looked at everyday environmental chemicals, things we can be exposed to through food, water, or smoking, and how they may relate to age-related macular degeneration.

The researchers found that higher levels of certain chemicals, like nitrates and thiocyanates, were linked with a higher chance of developing early macular changes. This doesn’t mean these chemicals cause macular degeneration, but it does add to what we already know, that eye health is influenced by more than just age or genetics.

When we talk about macular degeneration, we’re usually thinking about family history, smoking, heart health, and diet. This research simply reminds us that long-term exposure and lifestyle factors are also important and macular changes often start quietly, long before vision is affected.

If you have a family history of macular degeneration, smoke or have smoked, or are thinking about protecting your eye health as you get older, regular eye examinations are really important. Early changes can often be detected well before you notice any symptoms.

Which lifestyle factor do you think plays the biggest role in protecting vision as we age: diet, heart health, or environment?

We’re seeing more short-sighted kids and they're spending less time outdoors.

More children who are becoming short-sighted at a younger age. Recent Australian data shows that around 1 in 4 children tested last year were diagnosed with myopia.

One of the biggest changes?

Kids are spending far less time outdoors and a lot more time on screens, often 6 to 9 hours a day.

Spending time outside is really important. Natural light and distance viewing help support healthy visual development, especially during the school years. While genetics play a role, lifestyle is a big part of what we’re seeing in the consulting room. Many children don’t realise they’re struggling to see clearly, and it can quietly affect their learning and confidence at school.

If your child is squinting, complaining of headaches, or finding schoolwork harder than usual, an eye examination can make a real difference. We recommend annual eye tests for school-aged children, even if there are no obvious problems.

Smart glasses are becoming a real thing

I’m getting more questions lately about smart glasses, and it’s no surprise. Experts predict this technology could grow into a $200 billion market by 2040, with many more people expected to use them over the next decade.

The technology is exciting, especially with AI now being built into eyewear. But as with any new tech, it’s important to think about how it actually fits into your everyday vision and eye comfort.

Smart glasses aren’t just a gadget, they’re something you’ll be wearing on your eyes for long periods of time.

Are you're thinking buying a pair? Before you do it, it’s worth having a chat with your optometrist. We can help make sure they suit your vision, your lifestyle, and your long-term eye health.

Weight-loss medications and vision, what should you know?

Robbie Williams recently shared that he’s been experiencing blurry vision since starting the weight-loss medication Mounjaro (tirzepatide). He described audience members appearing as indistinct shapes, even up close.

He believes the change may be linked to the medication rather than age. Around the same time, a 2024 study published in JAMA (involving over 17,000 patients) reported higher rates of certain serious eye conditions, particularly a rare optic nerve problem, among some people using semaglutide-based medications. This doesn’t mean these medicines are “bad”. They can be very effective and, for many people, life-changing. But it does remind us that any new medication should be monitored, including its effect on vision.

In our practice, we’re hearing more people mention visual changes after starting these injections. Not everyone is affected, but it’s important to pay attention.

If you use Mounjaro, Ozempic, or Wegovy and notice:
- blurry vision
- difficulty focusing
- reduced clarity at any distance
or a sense that your eyes just “aren’t working the same”, please have your eyes checked, and let your prescribing doctor know. Early assessment matters.

These medications can be part of a healthy plan, and your eye health deserves to be part of that conversation.

Have you noticed any changes in your vision after starting a new medication?

New year, and the eyes truly are windows into our health.

A routine eye check for an 8-year-old girl in the United States turned out to be far more important than anyone expected. Her GP noticed one eye seemed weaker and recommended an eye test.

During the examination, the optometrist saw swelling in her optic nerve, a sign that something deeper was happening. He urged the family to seek urgent care. When answers didn’t come straight away, he followed up again and directed them to a specialist children’s hospital. Further testing revealed a benign brain tumour. Surgery was performed, and her vision, and likely her long-term health, were protected.

And remember: eye exams are not “just about glasses”, they help us detect changes linked to neurological and systemic conditions, often before symptoms appear.

As we step into a new year, many of us set goals to eat better, exercise more, or reduce stress. I encourage you to add this powerful habit to your goals: Make regular eye examinations part of your health check-ups for you and your family. Your future self will thank you.

When was the last time you or your child had a full eye examination?

Back to school, clear vision!

Back to school means busy minds and hard-working eyes.
A quick eye check can help make learning clearer and more comfortable.

UV doesn't take a day off - and neither should your eye protection.

Even on cloudy days, UV rays still reach our eyes and can quietly contribute to:
- Cataracts
- Macular damage
- Sunburn of the eye (yes, it happens)
- Premature ageing of the delicate skin around the eyes.

Sunglasses with UV protection, prescription or non-prescription, help shield your eyes every day, not just at the beach.

If you are unsure whether your current sunglasses protect your eyes, bring them in, we're happy to check.

Protect your eyes today, see clearly tomorrow. Book your eye check or drop by the practice, we're here to help.
