Cataracts are one of the most common vision problems, especially in adults over 60. But what exactly causes a cataract to develop and is there anything you can do to prevent it?

At Dakota Eye Institute, we help patients in Bismarck, throughout North Dakota, and surrounding areas understand the risks, symptoms, and treatments for cataracts. In this post, we explore the most common causes of cataracts and when you should see a cataract doctor near you.

What Is a Cataract?

A cataract occurs when the clear lens inside your eye becomes cloudy, leading to blurry vision, glare, and difficulty seeing at night. It’s a progressive condition that typically worsens over time and it’s one of the leading causes of vision loss worldwide.

Luckily, cataract surgery is a safe and effective solution offered by our experienced cataract surgeons in Bismarck, North Dakota.

What Causes Cataracts?

There are several reasons why cataracts form, many of which are age-related or genetic. Here are the most common causes:

Aging (Age-Related Cataracts)
The most common cause of cataracts is natural aging. As we get older, proteins in the eye’s lens break down and clump together, clouding your vision.
UV Exposure
Too much exposure to sunlight – especially without UV-blocking sunglasses – can increase your risk of cataracts. UV rays damage the proteins in your eye’s lens.
Medical Conditions
Certain health issues like diabetes, high blood pressure, and obesity have been linked to an increased risk of cataracts.
Eye Injuries or Surgeries
Previous eye trauma or surgery can lead to what are called secondary cataracts. These are more common in people with a history of eye injuries.
Genetics
Family history plays a role – some people are genetically predisposed to develop cataracts earlier in life.
Smoking & Alcohol Use
Smoking increases oxidative stress on the eyes, and excessive alcohol consumption may contribute to lens damage.
Medications
Long-term use of corticosteroids, such as prednisone, can lead to the development of cataracts.

Common Cataract Symptoms

Knowing the signs of a cataract can help you catch it early. Here are some common cataract symptoms to watch for:

Blurry or cloudy vision
Trouble seeing at night
Light sensitivity or glare
Faded or yellowed colors
Halos around lights
Frequent changes in glasses or contacts prescription

If you’re experiencing any of these symptoms, schedule an evaluation with a cataract doctor in Bismarck or anywhere in North Dakota.

How Are Cataracts Treated?

The only proven treatment for cataracts is cataract surgery. During this procedure, your cloudy lens is removed and replaced with a clear intraocular lens (IOL). We offer several types of cataract IOL lenses, including premium options that may reduce your need for glasses.

Patients often ask about cataract surgery costs. The price can vary depending on the type of cataract lenses used, your insurance coverage, and whether you choose advanced technology like laser-assisted surgery or premium IOLs.
