If you have noticed blurred vision, glare from headlights, or colors that seem less vibrant than they once did, it’s possible you’re suffering from cataracts. Indeed, they are one of the most common reasons for vision changes in aging eyes, and understanding how they develop can help you take proactive steps to protect your eye health.
The team at Holtebeck Eye Center in Brookfield focuses on educating patients about cataracts and providing advanced cataract surgery when needed. Learning what leads to a clouded lens can help you feel more confident about your vision and your options. So, let’s explore what causes cataracts.
What Causes Cataracts as We Age?
The most common answer to what causes cataracts is the natural aging process. Inside the eye, the lens sits behind the iris and helps focus light onto the retina so you can see clearly. When the lens is clear, it allows sharp images to form.
Over time, the proteins and fibers within the lens begin to change. They can break down and cluster together, which leads to clouding. As this clouded lens develops, it scatters and blocks light instead of focusing it properly. These effects are why many people experience blurry vision, faded colors, or difficulty seeing at night.
Cataracts often develop in both eyes, although they may not progress at the same speed. One eye may seem more affected than the other, which can create uneven vision changes.
Other Risk Factors That Contribute to Cataracts
While aging is the leading cause, several other factors can increase the likelihood of developing cataracts or cause them to progress more quickly.
These include:
- Diabetes and other systemic health conditions
- A family history of cataracts
- Previous eye injuries or inflammation
- Past eye surgery, including procedures for glaucoma
- Long term use of corticosteroid medications
- Radiation treatment for certain medical conditions
Lifestyle habits also play a role. Smoking, excessive alcohol use, and prolonged exposure to ultraviolet light without proper eye protection have all been associated with a higher risk of cataracts.
Understanding these risk factors is important for maintaining long term eye health. Even though cataracts are common, knowing what causes cataracts can help you make informed choices about protecting your vision.
How Cataracts Affect Vision
As a cataract grows, the lens becomes thicker and less flexible. The increasing cloudiness prevents a sharply defined image from reaching the retina. This leads to symptoms such as blurred vision, glare sensitivity, halos around lights, and difficulty reading in low light.
These vision changes can interfere with daily activities such as driving, reading, or enjoying hobbies. Because symptoms often develop gradually, many people adjust without realizing how much their sight has changed.
Routine comprehensive eye exams are essential for detecting cataracts in their early stages. Dr. Holtebeck and Dr. Abbas can monitor changes in your vision and discuss whether updated glasses, lifestyle adjustments, or cataract surgery may eventually be appropriate.
Can Cataracts Be Prevented?
There is no guaranteed way to prevent cataracts, but certain healthy habits may support your overall eye health.
Scheduling regular eye exams allows early detection of cataracts and other conditions. Managing medical conditions such as diabetes is also important. Wearing sunglasses that block ultraviolet light may help protect the eyes from sun related damage. Choosing a balanced diet rich in fruits and vegetables provides antioxidants and nutrients that support healthy aging eyes. Reducing smoking and limiting alcohol intake can also benefit long term vision.
These steps may not eliminate the risk entirely, but they can contribute to healthier eyes over time.
