Cataract is a clouding of the eye’s natural lens, which normally focuses light onto the retina. As the lens becomes cloudy, vision gradually becomes blurry, dim, or distorted.
Common symptoms
Blurry or cloudy vision
Difficulty seeing at night
Increased sensitivity to glare (e.g., headlights)
Colors appearing faded or yellowed
Frequent changes in eyeglass prescription
Seeing halos around lights
Double vision in one eye
Risk factors
Aging (most common cause)
Diabetes
Smoking
Excessive UV light exposure
Long-term steroid use
Eye injuries or previous eye surgery
Family history
Treatment
Early cataracts may be managed with:
Stronger glasses or contact lenses
Brighter lighting
Anti-glare sunglasses
When vision significantly affects daily activities, the standard treatment is cataract surgery, in which the cloudy lens is removed and replaced with an artificial intraocular lens (IOL). Cataract surgery is one of the most common and successful surgical procedures worldwide.
Cataracts are most commonly associated with aging, but they can occur at almost any age.
Typical age ranges:
40s–50s: Early cataract changes may begin, often without noticeable symptoms.
60s and older: Cataracts become much more common and are more likely to affect vision.
By age 80: More than half of people have either developed cataracts or undergone cataract surgery.
