A cataract is a clouding of the eye’s natural lens that gradually reduces vision clarity. The lens sits behind the iris and pupil and helps focus light onto the retina. As cataracts develop, the lens becomes less transparent, causing blurred vision, glare, difficulty with night driving, and faded colors.
Cataracts are extremely common and most often related to aging, although they can also develop due to medical conditions, medications, or eye trauma.
Cataract symptoms often progress slowly and may include:
Several types of cataracts exist, including:
Nuclear sclerotic cataracts – affect distance vision first
Cortical cataracts – cause glare and contrast problems
Posterior subcapsular cataracts – often affect reading and night vision early
Each type can affect vision differently and may progress at different speeds
Cataracts can develop due to:
Natural aging changes in the lens
Diabetes or blood sugar fluctuations
Long-term steroid use
UV light exposure
Smoking
Previous eye injury or surgery
Early cataracts may be managed temporarily with updated glasses or lighting adjustments. However, cataract surgery is the only permanent treatment once vision impairment affects daily life.
During surgery, the cloudy lens is removed and replaced with a clear artificial intraocular lens (IOL).
You should schedule an eye exam if cataract symptoms begin interfering with:
Driving
Reading
Work or hobbies
Safety or independence
Early evaluation allows for proper monitoring and surgical planning when appropriate.
