What Causes Cataracts and Who Is Most at Risk

Cataracts are one of the most common age-related eye conditions, but many people are unsure why they happen or whether they are at higher risk. A cataract develops when the eye’s natural lens becomes cloudy, making vision look blurry, dull, or hazy. At Central DuPage Vision Center, we help patients in Winfield understand cataracts early so they can protect their sight and know when treatment may be needed.

How Cataracts Develop

The lens inside your eye is normally clear, which helps focus light properly onto the retina. Over time, proteins in the lens can begin to break down and clump together. This causes the lens to lose its clarity. As cataracts progress, everyday activities like reading, driving at night, or seeing fine detail can become more difficult. Cataracts usually develop gradually, which is why changes in vision can be easy to miss at first.

Common Causes of Cataracts

Aging is the leading cause of cataracts, but it is not the only one. Several factors can contribute to lens clouding, including:

  • Natural age-related changes in the eye
  • Long-term UV exposure
  • Diabetes
  • Smoking
  • Eye injuries
  • Extended use of steroid medications
  • A family history of cataracts

These factors can increase the likelihood of cataracts developing earlier or progressing faster.

Who Is Most at Risk?

While cataracts are most often associated with older adults, some people face a higher risk than others. Adults over 60 are more likely to develop cataracts simply because the lens changes over time. Patients with diabetes may also be more vulnerable, since blood sugar changes can affect the lens.

People who spend a great deal of time in the sun without proper UV protection may place added stress on their eyes. Smokers and those with a history of eye trauma or previous eye surgery may also have a greater chance of developing cataracts. In some cases, cataracts can even appear earlier in life due to genetics, medical conditions, or medication use.

Signs You Should Not Ignore

Because cataracts often develop slowly, the symptoms may seem minor at first. It is important to schedule an eye exam if you notice:

  • Blurry or cloudy vision
  • Increased glare from headlights or sunlight
  • Trouble seeing at night
  • Colors looking faded or yellowed
  • Frequent prescription changes

These symptoms do not always mean you have cataracts, but they should be evaluated promptly.
