Early Signs of Cataracts: What to Notice and When to Act
Cataracts develop slowly, so early changes are easy to dismiss. Here are the signs worth paying attention to, and what an assessment involves.

A cataract is a clouding of the eye's natural lens. Because the change is usually slow, many people adapt without realising how much their vision has altered. Recognising the early signs helps you seek assessment at the right time.
What are the early signs of cataracts?
- Vision that looks slightly cloudy, hazy or 'filmy'.
- Increased glare from headlights, sunlight or bright lamps.
- Halos around lights, particularly at night.
- Colours that appear faded or yellow-tinged.
- Needing brighter light to read.
- Frequent changes to your glasses prescription.
Who is more likely to develop cataracts?
Age is the most common factor. Others include diabetes, smoking, long-term use of steroid medication, previous eye injury or surgery, and prolonged unprotected exposure to sunlight.
When should I see an ophthalmologist?
Book an eye examination if you notice any of the changes above, or if your vision is affecting driving, reading or work. A comprehensive examination can confirm whether a cataract is present and rule out other causes of blurred vision.
Sudden vision loss, eye pain or flashes and floaters are not typical of cataracts and should be assessed urgently.
Is surgery always needed?
Not immediately. Early cataracts may be managed with updated glasses and better lighting. Surgery is considered when the cataract interferes with daily life. Your surgeon will discuss timing, lens options and risks with you.
