CATARACTS EXPLAINED
Posted by: Talya Eye Center in Uncategorized
Cataract plays a crucial role in focusing light onto the retina at the back of the eye. When the lens becomes cloudy, it can lead to blurred or hazy vision, decreased contrast sensitivity, and difficulty seeing in low light conditions.
A cataract is a clouding of the natural lens in the eye that affects vision. The lens, located behind the iris and the pupil, plays a crucial role in focusing light onto the retina at the back of the eye. When the lens becomes cloudy, it can lead to blurred or hazy vision, decreased contrast sensitivity, and difficulty seeing in low light conditions.
Cataracts are primarily associated with aging, and most people will experience some degree of lens clouding as they get older. However, cataracts can also develop due to other factors, including:
- Trauma: Injury to the eye can cause cataracts.
- Medical conditions: Certain diseases, such as diabetes, can contribute to the development of cataracts.
- Medications: Prolonged use of certain medications, such as corticosteroids, can increase the risk of cataracts.
- Excessive sun exposure: Ultraviolet (UV) radiation from the sun may contribute to cataract development.
- Genetics: A family history of cataracts may increase the risk.
- Smoking and alcohol consumption: These lifestyle factors have been associated with an increased risk of cataracts.
The symptoms of cataracts can include:
- Cloudy or blurry vision: This is a common early symptom.
- Fading of colors: Colors may appear less vibrant.
- Glare: Headlights, lamps, or sunlight may cause discomfort or difficulty seeing.
- Double vision: Seeing double in one eye.
Cataracts can be treated effectively with surgery, which involves removing the cloudy lens and replacing it with an artificial intraocular lens (IOL). Cataract surgery is a common and safe procedure, often performed on an outpatient basis, and it has a high success rate in restoring clear vision. If you suspect you have a cataract or are experiencing changes in your vision, it’s important to consult with an eye care professional for an accurate diagnosis and appropriate treatment options.
