A cataract is a clouding of the eye’s naturally clear lens, and it is one of the most common causes of blurred vision as we age. The good news is that cataracts are highly treatable, and modern surgery is one of the safest and most successful procedures in medicine. Understanding the early signs helps you act before your daily life is affected.
Common symptoms
Cataracts usually develop slowly, so the changes can be easy to overlook at first.
- Cloudy, blurred or dim vision.
- Increasing difficulty seeing at night.
- Sensitivity to light and glare, especially from headlights.
- Colours appearing faded or yellowed.
- Frequent changes to your glasses prescription.
What causes cataracts
Ageing is the most common cause, as proteins in the lens gradually break down and clump together. Other contributing factors include diabetes, prolonged exposure to ultraviolet sunlight, smoking, certain medications such as steroids, and previous eye injury. In a sunny climate like the UAE, consistent UV protection is an important preventive habit.
How cataracts are treated

In the early stages, stronger glasses and better lighting may help. When a cataract begins to interfere with reading, driving or work, surgery is the definitive solution. The cloudy lens is gently removed and replaced with a clear artificial lens, often through a tiny incision and usually as a quick day-case procedure. Most patients notice a dramatic improvement in vision within days.
