What are cataracts?
Cataracts are very common. In fact, they’re the main cause of impaired vision worldwide!
Blurry vision refers to a lack of sharpness or clarity in eyesight, making objects or details appear hazy, out of focus, or unclear. The blurriness can affect near vision, distance vision, or both, and it may be temporary or chronic. Blurry vision is not a condition itself, it’s more a symptom of other eye conditions or simply a sign that you may need new or updated glasses or contact lenses.
What causes cataracts?
The exact cause of cataracts is not always known, but several factors contribute to their development. Here are some common causes:
Ageing
The primary cause of cataracts is ageing. As individuals grow older, the proteins within the eye's lens can break down and clump together, causing cloudiness.
Genetics
Cataracts can have a genetic component, meaning they may run in families. Some people may be more predisposed to developing cataracts due to their genetic makeup.
Trauma
Physical injury to the eye can contribute to the development of cataracts. Blunt trauma or injuries that cause damage to the lens may increase the risk.
Medical Conditions
Certain medical conditions can increase the likelihood of cataracts, including diabetes. People with diabetes are at a higher risk of developing cataracts at an earlier age
Exposure to Ultraviolet (UV) Radiation
Prolonged exposure to sunlight, especially without adequate eye protection, may contribute to cataract formation.
Smoking and Alcohol Consumption
Smoking and excessive alcohol consumption have been linked to an increased risk of cataracts.

Cataract symptoms
Here are some common symptoms of cataracts:
- Blurred Vision: Vision may appear cloudy or blurry, similar to looking through a foggy or frosted glass
- Difficulty Seeing at Night: Cataracts can cause increased sensitivity to glare, making it challenging to drive or see well in low-light conditions
- Faded Colours: Colours may seem less vibrant or appear yellowed due to the clouding of the eye's lens
- Double Vision: Cataracts can cause double vision in one eye, which may improve when the affected eye is closed
- Frequent Changes in Prescription Glasses: Individuals with cataracts may notice that their eyeglass or contact lens prescription needs frequent adjustments
- Halos Around Lights: Bright lights, such as car headlights or street lights, may appear surrounded by halos or glare
- Poor Night Vision: Difficulty seeing clearly in dim lighting or darkness may be a symptom of cataracts
- Progressive Vision Impairment: Cataracts often develop slowly over time, causing a gradual decline in vision. Initially, individuals may not notice significant changes until the cataract becomes more advanced
Treatment for cataracts
The primary treatment for cataracts is surgical intervention. Cataract surgery is a common and highly successful procedure that involves removing the cloudy natural lens and replacing it with an artificial intraocular lens (IOL). There are two types of cataract surgery: small incision cataract surgery (phacoemulsification) and extracapsular cataract extraction. These surgeries are usually done on an outpatient basis, so you shouldn’t need to stay at the hospital overnight, and it usually takes less than an hour to perform.
Cataract surgery is considered one of the safest and most successful surgical procedures, with a high rate of patient satisfaction. If you suspect you have cataracts or experience vision changes, it's essential to consult with your trusted Spec-Savers Optometrist for a thorough examination and personalized treatment plan.
