What Are Cataracts?

Cataracts are a common eye condition that affects millions of people worldwide, particularly as they age. A cataract occurs when the natural lens of the eye becomes cloudy, leading to blurred vision and difficulty performing daily activities. While cataracts may sound alarming, they are treatable through a safe and effective surgical procedure.

In this blog, we’ll explore what cataracts are, how they develop, their symptoms, and how they can be treated to restore clear vision.

What Are Cataracts?

A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil. The lens of the eye is crucial for focusing light onto the retina, which then sends visual signals to the brain. In a healthy eye, this lens is clear, allowing for sharp, crisp images. However, when a cataract develops, the lens becomes cloudy, leading to a decrease in vision.

What Causes Cataracts?

Cataracts are most often associated with ageing, as the proteins in the lens begin to break down and clump together. However, they can also be caused by other factors, including:

• Genetics: A family history of cataracts can increase your risk.
• Medical conditions: Diabetes and other medical conditions can contribute to their development.
• Lifestyle choices: Smoking and prolonged exposure to ultraviolet sunlight can accelerate cataract formation.
• Eye injuries or surgeries: Past injuries or surgeries can make the eye more susceptible to cataracts.

Common Symptoms of Cataracts

If you’re wondering whether you might have cataracts, here are some common symptoms to watch for:

• Blurry Vision: The most noticeable symptom of cataracts.
• Sensitivity to Light: Bright lights or glare may feel uncomfortable.
• Faded Colors: Colors may appear dull or less vibrant.
• Difficulty Seeing at Night: Night driving or dim light settings can become challenging.
• Halos Around Lights: A halo effect around light sources, especially at night.

How Are Cataracts Treated?

The only way to treat cataracts is through surgery, where the cloudy lens is replaced with a clear artificial lens, known as an intraocular lens (IOL). Cataract surgery is a highly advanced and routine procedure with a success rate of over 95%. It is typically performed on an outpatient basis, and patients experience improved vision almost immediately.

When Should You Seek Help?

If you notice any of the symptoms of cataracts or your vision is interfering with daily activities, it’s important to consult an eye specialist. Early diagnosis can help you understand your options and plan for treatment.
