What Is a Cataract?
The natural lens inside the eye helps focus light onto the retina. With a cataract, this lens gradually becomes cloudy, making it difficult for light to pass through clearly.
Cataracts usually develop slowly and may initially cause only minor changes in vision.
Common Symptoms of Cataract
Blurred or cloudy vision is one of the most common symptoms. Patients may also experience difficulty seeing at night, increased sensitivity to bright lights and glare, faded colours or frequent changes in spectacle power.
Some people may notice halos around lights or difficulty reading despite using their usual glasses.
How Is Cataract Treated?
In the early stages, changes in spectacles and improved lighting may help with visual tasks. However, when a cataract begins to interfere significantly with daily activities, cataract surgery may be recommended.
Modern cataract surgery involves removing the cloudy natural lens and replacing it with an artificial intraocular lens.
When Should You Consult an Eye Specialist?
If blurred vision, glare or difficulty with daily activities is becoming noticeable, a comprehensive eye examination can determine whether a cataract or another eye condition is responsible.
