Cataract Awareness and Prevention

Cataracts are one of the leading causes of vision impairment worldwide and become increasingly common with age. For patients in Paradise and across the Las Vegas valley, understanding what cataracts are, how they progress, and what you can do to protect your vision is an important part of long-term eye health.

What Are Cataracts and What Causes Them?

A cataract develops when the natural lens inside the eye gradually becomes cloudy, causing vision to blur over time. The lens is responsible for focusing light onto the retina, which is how you see clearly. When proteins in the lens break down and clump together, they block or scatter light, making images appear hazy, dim, or washed out.

Aging is the most common cause. As you get older, the proteins in your lens naturally deteriorate. However, cataracts can also be caused or accelerated by other factors, including diabetes, eye injuries or trauma, prolonged use of corticosteroid medications, smoking, excessive alcohol consumption, long-term UV exposure, and certain eye conditions such as uveitis. In some cases, cataracts are present at birth.

What Symptoms Should You Watch For?

Cataracts typically develop slowly, so early symptoms can be subtle. As the condition progresses, you may notice:

• Increasingly blurry or hazy vision, similar to looking through a foggy window
• Colors appearing faded, yellowed, or less vibrant than they used to be
• Increased sensitivity to glare from sunlight, headlights, or indoor lighting
• Difficulty driving at night due to glare or halos around lights
• Double vision in one eye
• Needing brighter light to read or perform close-up tasks
• Reduced contrast and depth perception, making it harder to judge distances

If you notice any of these changes, schedule a comprehensive eye exam. Early detection allows your eye doctor to monitor the cataract and help you maintain the best possible vision as it progresses.

How Are Cataracts Treated?

In the early stages, cataracts can often be managed without surgery. An updated eyeglass prescription, better lighting at home and work, anti-glare lens coatings, and magnifying tools can help you continue your normal activities. Your eye doctor will monitor your cataracts during regular exams and track any changes in your vision over time.

When cataracts begin to significantly interfere with daily life, such as making it difficult to drive, read, work, or enjoy hobbies, cataract surgery is typically recommended. During the procedure, an ophthalmologist removes the cloudy natural lens and replaces it with a clear artificial intraocular lens (IOL). Standard IOLs correct distance vision, though reading glasses may still be needed for close-up tasks. Newer multifocal and extended depth-of-focus IOLs can reduce dependence on glasses, though they are not suitable for every patient.

Cataract surgery is performed on an outpatient basis, and most patients experience noticeably improved vision within days. At Insight Vision Optometry, Las Vegas, our team provides cataract co-management, including pre-operative evaluation, guidance on IOL options, surgical referral, and post-operative follow-up care.

How Can You Reduce Your Risk of Developing Cataracts?

While cataracts cannot always be prevented, several lifestyle habits can help lower your risk or slow their progression:

• Wear sunglasses that block 100% of UVA and UVB rays whenever you are outdoors
• Quit smoking, as tobacco use is a well-established risk factor for cataracts
• Limit alcohol consumption
• Eat a balanced diet rich in fruits and vegetables, which provide antioxidants that support lens health
• Manage chronic conditions such as diabetes and high blood pressure with your primary care provider
• Exercise regularly to support overall health and circulation

When Should You Schedule an Eye Exam?

If you are over 40, have diabetes or other risk factors, or have noticed any changes in your vision, regular comprehensive eye exams are essential. Early cataracts often produce no noticeable symptoms, so routine screening is the most reliable way to detect them before they significantly affect your quality of life.
