Cataracts are the world's leading cause of vision loss — and one of the most treatable. If you've been told you have early cataracts, or if your vision has become progressively blurry, cloudy, or glare-sensitive, this guide will help you understand what's happening and what your options are.
What Is a Cataract?
A cataract is a clouding of the eye's natural lens, which sits behind the iris and pupil. The lens is normally clear, allowing light to focus sharply on the retina. As a cataract develops, the lens becomes increasingly opaque, scattering light and reducing the clarity of your vision.
Cataracts develop gradually and are most commonly age-related, though they can also be caused by injury, certain medications, or medical conditions like diabetes.
Early Warning Signs
- Blurry or foggy vision, especially for reading or detail work
- Increased sensitivity to glare — particularly from headlights at night
- Faded or yellowed colours
- Frequent prescription changes (needing stronger glasses more often)
- Double vision in one eye
- Halos around lights
Risk Factors
Age is the primary risk factor — most people over 60 have some degree of lens clouding. Other factors include diabetes, prolonged UV exposure, smoking, heavy alcohol use, eye injuries, and long-term use of corticosteroid medications.
When Is Surgery Needed?
Not all cataracts require immediate surgery. In the early stages, stronger glasses or better lighting may be sufficient. Surgery is typically recommended when the cataract begins to significantly impact your daily life — driving, reading, or recognising faces.
Cataract surgery is one of the safest and most commonly performed surgeries in the world. The clouded natural lens is removed and replaced with a clear artificial intraocular lens (IOL). Most people experience dramatically improved vision within days of the procedure.
