Here's a breakdown:
* What happens: The lens is made of mostly water and protein. As we age, these proteins can clump together and form cloudy areas in the lens. This clouding interferes with light passing through the lens, making vision blurry.
* Causes: Aging is the most common cause of cataracts. Other factors include:
* Diabetes: High blood sugar levels can damage the lens.
* Exposure to UV radiation: Sunlight can damage the lens over time.
* Certain medications: Some medications can cause cataracts as a side effect.
* Eye injury: A direct injury to the eye can damage the lens.
* Smoking: Smoking increases the risk of cataracts.
* Genetics: Some people have a genetic predisposition to cataracts.
* Symptoms:
* Blurred vision
* Difficulty seeing at night
* Double vision
* Halos around lights
* Faded colors
* Frequent changes in eyeglass prescriptions
* Treatment: The only way to remove a cataract is with surgery. Surgery involves removing the cloudy lens and replacing it with an artificial lens implant. Cataract surgery is very safe and effective.
It's important to note that cataracts don't always cause symptoms. Some people may have a cataract without noticing any change in their vision.
If you notice any changes in your vision, it's important to see an eye doctor. They can determine if you have a cataract and recommend the best treatment for you.
