You clean your glasses again, but the world still looks hazy. Headlights seem unusually bright at night, colours don't look as clear as they used to, and reading small print has become frustrating.
You may assume that you simply need a stronger glasses prescription. Sometimes the real issue is a cataract.
What Is a Cataract?
A cataract occurs when the natural lens inside the eye becomes cloudy. Instead of light passing clearly through the lens, the cloudiness can gradually affect how clearly you see.
Cataracts are commonly associated with ageing, but they can also occur for other reasons, including eye injuries, certain medical conditions or prolonged use of particular medicines.
Common symptoms include:
-
Blurry or cloudy vision
-
Difficulty seeing at night
-
Increased glare from headlights
-
Faded-looking colours
-
Frequent changes in glasses prescription
-
Difficulty reading or doing close-up work
-
Seeing halos around lights
Cataracts usually develop gradually, so many people don't notice how much their vision has changed until everyday activities become harder.
When Should You Consider Cataract Surgery?
A cataract does not automatically mean you need surgery immediately.
The important question is whether the cataract is affecting your daily life. If you are struggling to drive, read, work, recognise faces, watch television, or perform routine activities despite appropriate glasses, it's worth discussing treatment with an eye specialist.
Your eye doctor can examine the cataract and assess how much it is affecting your vision.
Why Is Surgery Done?
Cataract surgery removes the cloudy natural lens and replaces it with an artificial intraocular lens, commonly called an IOL.
The aim is to improve vision that has been affected by the cataract. Your surgeon will discuss which type of lens may be appropriate based on your eyes, lifestyle and visual requirements.
The Advice We Would Challenge
A common misconception is that you should wait until a cataract becomes “fully mature” before having surgery.
That isn't a useful rule.
Modern cataract surgery is generally considered when the cataract is causing enough visual difficulty to affect a person's quality of life. Waiting for vision to become extremely poor isn't necessarily beneficial.
At the same time, having a cataract doesn't mean surgery must happen immediately. The timing should be based on your symptoms and examination.
A Real-World Example
One of our clients had gradually stopped driving at night because headlights had become uncomfortable and road signs were harder to see.
They initially assumed the problem was simply their glasses. An eye examination showed a cataract contributing to the visual changes, allowing them to discuss whether surgery was appropriate rather than continuing to change spectacles without addressing the underlying issue.
What Happens Before Cataract Surgery?
Your eye specialist will examine your eyes and measure them carefully before surgery. These measurements help the surgeon plan the procedure and select an appropriate intraocular lens.
You'll also discuss your medical history, existing eye conditions, medications and visual expectations.
Cataract surgery is common, but it is still surgery. You should understand the expected benefits, possible risks, recovery and follow-up requirements before proceeding.
A Statistic Worth Knowing
The World Health Organization's 2024 eye-care information continues to identify cataract as one of the major causes of blindness globally.
That doesn't mean every person with a cataract needs immediate surgery. It does show why cataract-related vision loss is an important eye-health concern and why timely assessment matters.

Frequently Asked Questions
How do I know if I have a cataract?
Common signs include gradually blurred vision, glare, difficulty seeing at night, faded colours and frequent changes in your glasses prescription. An eye examination is needed for diagnosis.
Is cataract surgery painful?
The eye is numbed during the procedure, so significant pain during surgery is not expected. Some discomfort or irritation may occur during recovery.
How long does cataract surgery take?
The surgical procedure itself is usually relatively short, but your complete treatment journey includes pre-operative assessment, surgery and follow-up care. Your surgeon can explain the expected timeline for your individual case.
Don't Let Hazy Vision Become Your New Normal
If your vision has gradually become cloudy, night driving is becoming difficult, or glare is interfering with everyday activities, don't simply keep changing your glasses.
Book a comprehensive eye examination, find out whether a cataract is affecting your vision, and discuss the timing and options for treatment with a qualified eye specialist.
