Not every vision problem is the same — and knowing what you’re dealing with is the first step to protecting your sight. Below is a straightforward guide to some of the most common eye conditions we see, what to watch for, and when it’s time to book an assessment.
Keratoconus
Keratoconus is a progressive condition where the cornea thins and gradually bulges into a cone-like shape, distorting vision. It typically develops in the teens or twenties and can worsen over time if untreated.
Watch for: blurred or distorted vision that doesn’t fully correct with glasses, frequent prescription changes, increased light sensitivity, and eye rubbing habits. Learn more about Keratoconus and the Causes, Symptoms, Treatment Options.
Glaucoma
Often called “the silent thief of sight,” glaucoma damages the optic nerve, usually due to elevated pressure inside the eye. It progresses slowly and often without noticeable symptoms until vision loss has already begun — which is why regular screening matters more than symptom-watching.
Watch for: gradual loss of peripheral vision, though often there are no early symptoms at all — this is why routine eye pressure checks are so important.
Dry Eye Syndrome
Dry eye occurs when your eyes don’t produce enough quality tears to stay lubricated, leading to discomfort, irritation, and sometimes blurred vision. It’s especially common with increased screen time, certain medications, and seasonal changes.
Watch for: a gritty or burning sensation, redness, excessive tearing (counterintuitively, a symptom of dryness), and discomfort that worsens through the day.
Diabetic Eye Disease
Diabetes can affect the blood vessels in the retina over time, a condition known as diabetic retinopathy. It’s one of the leading causes of preventable vision loss in adults, and early stages typically have no symptoms at all.
Watch for: blurred vision, floaters, and dark spots — though by the time these appear, the condition may already be advancing, which is why annual screening for anyone with diabetes is strongly recommended.
Macular Degeneration
Macular degeneration affects the central part of the retina, gradually impacting the sharp, detailed vision needed for reading, driving, and recognising faces. It’s most common in people over 50.
Watch for: straight lines appearing wavy, difficulty recognising faces, and a blurred or blank spot in central vision.
When to Book an Assessment
Many of these conditions develop gradually and without obvious symptoms in their early stages — which is exactly why routine eye examinations matter, even when your vision feels “fine.” If you’re experiencing any of the warning signs above, or it’s simply been over a year since your last comprehensive eye check, it’s worth booking an assessment.
