What is a Cataract?
A cataract is the clouding of the natural lens of your eye. This lens sits behind the colored part (iris) and helps focus light so you can see clearly. When it becomes cloudy, your vision can become blurry, dull, or faded — like looking through a frosted window. If you’re wondering what is cataract or looking for a simple cataract definition medical, it refers to the cloudiness that blocks or distorts light entering the eye.
Cataracts usually develop slowly over time and are most common with aging, but they can also be caused by diabetes, injury, long-term UV exposure, or certain medications. The cataract meaning often becomes clearer when you understand that it’s a progressive, vision-blurring condition.
Signs You Might Have a Cataract
Ask yourself the following questions:
- Do objects look blurry or hazy — even with glasses?
- Do you have trouble seeing clearly at night?
- Are the lights too bright or glaring, especially while driving?
- Do colors seem dull or yellowish?
- Are you needing frequent changes in your glasses prescription?
If you answered yes to any of these, you might have a cataract. These are considered some of the early symptoms of cataract, and it’s best to consult a specialist.
What Should You Do?
Don’t worry, what are cataracts is a common question, and they are very treatable. A quick and painless eye examination by an ophthalmologist can confirm if you have a cataract. If needed, cataract surgery is one of the safest and most successful procedures today, often restoring clear vision within days.
