Cataracts develop gradually, often going unnoticed until vision is significantly impaired. Early detection is crucial to preserving eyesight and preventing complications like glaucoma or blindness. Key early signs include:
- Blurry or cloudy vision: Objects may appear out of focus, like looking through fog.
- Light sensitivity: Bright lights or glare become uncomfortable, especially at night.
- Halos around lights: Circular glows around headlights or streetlights are common.
- Frequent prescription changes: Rapid shifts in glasses or contact lens needs.
- Faded or yellowed colors: Colors lose vibrancy, appearing dull or tinted.
Risk factors include aging, diabetes, UV exposure, smoking, and long-term corticosteroid use. Regular eye exams, especially after age 40, are key to early detection. Protect your vision by wearing UV-blocking sunglasses, quitting smoking, and maintaining a healthy lifestyle. If you notice changes in your vision, schedule an eye exam promptly to address potential cataracts before they progress.

What Are Cataracts and How Do They Form?
To understand cataracts, it helps to know how they develop and what signs to watch for.
A cataract forms when the lens of the eye, which focuses light onto the retina, becomes cloudy. The lens is mostly made of water and proteins arranged in a way that keeps it clear. However, when these proteins clump together, they create cloudy areas that scatter light, leading to blurry vision.
Cataracts can form in one or both eyes, but they don’t always progress at the same pace. As they develop, they interfere with light focusing, causing symptoms like blurred vision, dull or faded colors, glare, and halos around lights.
What Causes Cataracts
Aging is the most common cause of cataracts. As we age, the proteins in the lens naturally break down. By the time Americans reach 80 years old, over half either have cataracts or have undergone surgery to remove them.
Exposure to UV light is another major factor. Over time, ultraviolet rays damage the proteins in the lens, which is why protecting your eyes from the sun is so important. Medical conditions, particularly diabetes, also play a significant role. High blood sugar levels affect the lens, increasing the risk of cataracts. Lifestyle habits like smoking and heavy drinking can speed up cataract formation by introducing harmful chemicals into the body and impairing nutrient absorption.
Other contributing factors include prior eye surgeries, exposure to certain chemicals, electric shocks, specific medications, and even genetics. All of these factors can gradually impact the clarity of the lens, setting the stage for cataract development.
How Cataracts Progress Over Time
Cataracts usually develop slowly, with changes unfolding over months or even years.
In the early stage, also called the incipient stage, the lens begins to cloud, though symptoms may be mild or go unnoticed. Interestingly, some people with nuclear cataracts might experience temporary improvement in near vision, a phenomenon often referred to as "second sight."
As cataracts progress to the intumescent stage, the cloudiness becomes more pronounced, and the lens may swell. Vision issues like noticeable blurring, trouble seeing at night, and heightened sensitivity to light become more apparent.
During the mature stage, the lens is fully clouded, significantly impairing vision. Everyday activities become challenging, colors may appear faded or take on a yellowish tint, and frequent changes in eyeglass prescriptions are often needed.
In the hypermature stage, the lens becomes densely opaque and can even shrink or dislocate. This advanced stage can lead to severe complications, such as glaucoma, which results from increased eye pressure. If untreated, glaucoma can cause further vision loss or even blindness.
The speed at which cataracts progress varies widely and depends on factors like overall health, diabetes management, UV exposure, and lifestyle choices. Acting early is crucial – timely treatment can stop cataracts from reaching advanced stages, where complications become more likely and surgeries are more complex.
Denver Eye Surgeons closely monitors cataract development to determine the best time for intervention. Detecting cataracts early allows for more effective treatment, as discussed in the next sections.
Early Warning Signs of Cataracts
Recognizing the early signs of cataracts can help you seek timely treatment. These symptoms often appear gradually, making regular eye exams essential for early detection.
Blurry or Cloudy Vision
One of the first signs of cataracts is blurry or cloudy vision, where everything seems slightly out of focus – almost like looking through a foggy window. This happens because the clouded lens scatters light before it reaches the retina, which reduces sharpness and contrast. You might notice this when reading street signs in low light or needing extra illumination for close-up tasks. Unlike temporary blurriness caused by eye strain, cataract-related vision changes tend to linger and worsen over time.
Light Sensitivity and Glare Problems
Increased sensitivity to bright light, known as photophobia, is another early indicator. Bright sunlight, headlights, or even indoor lamps may feel uncomfortably harsh. You might find yourself squinting more often or avoiding places with intense lighting. Driving can become particularly challenging, as glare from other vehicles or the road can make it hard to see clearly.
Halos Around Lights
Seeing halos – those glowing rings around light sources – is a common symptom, especially noticeable at night. Streetlights, car headlights, and other light sources may appear surrounded by bright circles. This happens because cataracts cause the lens to scatter light unevenly. These halos can make night driving especially hazardous by blurring objects and reducing clarity.
Frequent Changes in Glasses Prescription
If you find yourself needing new glasses more frequently than usual, it could be an early sign of cataracts. This occurs because protein buildup on the lens affects how light passes through to the retina, leading to rapid changes in vision. Unlike typical age-related adjustments, these frequent prescription updates may indicate cataract progression.
Faded or Yellowed Colors
Cataracts can also alter how you perceive colors, making them seem faded or yellowish over time. This happens because the lens often develops a yellow or brown tint, which filters out certain hues. For instance, white objects might appear more yellow, and distinguishing between similar colors can become challenging. Everyday activities like choosing clothes, reading color-coded information, or appreciating artwork may be affected. Many people only realize how much their color vision has changed after cataract surgery restores it.
According to the National Eye Institute, over half of Americans aged 80 or older either have cataracts or have undergone cataract surgery. While the severity of symptoms can vary, regular eye exams remain the best way to detect cataracts early and manage them effectively.
Who Gets Cataracts Most Often?
Knowing who is more likely to develop cataracts can help you stay proactive about your eye health. While cataracts can occur at any age, certain factors greatly increase the chances of developing them.
Age and Health Conditions That Increase Risk
Age is the biggest factor when it comes to cataracts. They often develop naturally as part of the aging process, with the risk rising significantly after the age of 60. This happens because, over time, the proteins in the eye’s lens break down and clump together, causing the cloudiness that defines cataracts.
Diabetes is another major contributor. If you have diabetes, your odds of developing cataracts are two to five times higher compared to someone without the condition. Elevated blood sugar levels can alter the lens, leading to cataracts earlier in life. For those managing diabetes, keeping blood sugar in check and scheduling regular eye exams is critical.
Long-term use of corticosteroids can also increase your risk, especially when taken in high doses or over extended periods. These medications can disrupt the lens’s metabolism, making it more prone to clouding. Other factors include previous eye surgeries, injuries, or genetic disorders. If you’re on corticosteroids for conditions like asthma or arthritis, it’s a good idea to talk with your doctor and eye care provider about keeping an eye on your vision.
In addition to age and health issues, your daily habits and surroundings also play a role.
Lifestyle and Environmental Risk Factors
Everyday choices and environmental exposures can have a big impact on cataract development. Smoking is a preventable risk factor that speeds up lens clouding. Chemicals in cigarettes damage the proteins in your lens and reduce the antioxidants that protect your eyes.
Drinking too much alcohol can harm eye tissues and increase your risk of cataracts. Heavy alcohol use also interferes with your body’s ability to absorb nutrients that support eye health.
Prolonged exposure to ultraviolet (UV) light is another key factor. UV rays from sunlight gradually damage the proteins in your lens, leading to cataracts over time. This is particularly a concern in sunny, high-altitude areas like Colorado, where UV exposure is greater. People who spend a lot of time outdoors – whether for work, sports, or leisure – are especially at risk.
Demographics also play a role. Certain ethnic groups, such as African Americans and Hispanics, may face a higher likelihood of developing cataracts earlier due to genetic factors and health disparities.
How Often You Should Get Eye Exams
If you’re over 60, an annual eye exam is a must to catch cataracts and other age-related eye issues early. This becomes even more important if you have diabetes, a history of eye problems, or take medications like corticosteroids that increase cataract risk.
For those with diabetes or other chronic conditions affecting vision, eye care providers may suggest exams every six months. Similarly, people on long-term corticosteroids should discuss more frequent monitoring with their healthcare team.
As the population ages, cataract cases are expected to double by 2050. Regular screenings are essential for early detection and timely treatment. Increased awareness and better access to eye care have already improved early diagnosis rates in recent years.
For residents in the Denver area, Denver Eye Surgeons provides comprehensive cataract screenings and same-day appointments. Their team specializes in tailored care for individuals over 60 or those with diabetes, emphasizing the importance of routine monitoring to maintain eye health.
Staying on top of regular exams not only helps detect cataracts early but also supports overall vision health for years to come.

When to See an Eye Doctor
Recognizing when to seek professional eye care can be the key to protecting your vision and avoiding serious complications. While cataracts often develop slowly, certain symptoms demand immediate attention. Knowing what to expect during an eye exam can also help you feel more prepared for the process.
Symptoms That Require Immediate Attention
If you notice sudden changes in your vision, don’t wait to act. Rapid blurring, double vision, or a sudden loss of sight could signal advanced cataracts or other serious eye conditions that need urgent medical care.
A cloudy or white appearance in the pupil is another red flag, often indicating advanced cataract development. This visible change suggests the lens has become significantly cloudy, requiring prompt treatment to prevent further issues.
Everyday activities becoming difficult – like struggling to read street signs, recognizing faces, or driving at night – are also signs it’s time to see an eye doctor. Frequent changes in your eyeglass prescription, increased sensitivity to glare, or seeing halos around lights, especially at night, are warning signs that should not be ignored. These symptoms not only suggest cataract progression but can also make activities like night driving unsafe.
Posterior subcapsular cataracts, in particular, can worsen quickly, sometimes advancing within just a few months. If you’ve been diagnosed with this type, it’s crucial to stay on top of follow-up appointments and report any changes in your symptoms immediately. Acting quickly can help protect your vision and avoid complications.
What to Expect During a Cataract Eye Exam
If you experience any of these warning signs, the next step is a comprehensive eye exam. A cataract evaluation typically includes several important diagnostic tests:
- Visual acuity testing with an eye chart to measure how clearly you can see.
- Slit-lamp examination to closely inspect the lens and other eye structures.
- Retinal assessment to evaluate the overall health of your eye.
- Intraocular pressure measurement to check for glaucoma, which can sometimes accompany advanced cataracts.
To examine the internal structures of your eye, your doctor will dilate your pupils using special eye drops. This may temporarily blur your vision for a few hours, so arranging for transportation home is a good idea. Administrative steps like check-in will be handled before the exam begins.
After completing the evaluation, your doctor will review the results and discuss the next steps. Depending on the severity of the cataracts, this could involve monitoring their progression, updating your prescription, or exploring surgical options if your vision is significantly affected.

How to Prevent Cataracts and Keep Eyes Healthy
While you can’t completely eliminate the risk of cataracts, there are effective ways to reduce the chances and slow their progression. By making smart, everyday choices, you can protect your vision and maintain healthier eyes.
Daily Habits to Protect Your Vision
One of the best ways to guard against cataracts is to shield your eyes from UV light. Prolonged exposure to UV rays can damage the proteins in your eye’s lens, increasing the likelihood of cataracts. Opt for sunglasses that block 99–100% of UVA and UVB rays, and don’t forget a wide-brimmed hat for extra protection.
Another crucial step is quitting smoking. Smokers are twice as likely to develop cataracts compared to non-smokers, as the harmful chemicals in cigarettes can damage the lens over time. The good news? It’s never too late to quit – stopping now can still make a positive difference for your eye health.
Limiting alcohol intake is another simple way to support healthy eyes.
Your diet also plays a key role. Foods packed with antioxidants, such as vitamin C, vitamin E, lutein, and zeaxanthin, can help protect your eyes. Leafy greens like spinach and kale, citrus fruits, colorful veggies, and omega-3-rich fish are excellent choices to lower cataract risk and boost overall eye health.
These habits work hand-in-hand with managing any existing health conditions that could impact your vision.
Managing Health Conditions That Affect Your Eyes
Chronic conditions like diabetes can significantly increase your risk of cataracts. Keeping your blood sugar levels in check, maintaining healthy blood pressure, eating a balanced diet, and staying active are all essential steps to protect your eyesight.
For those managing diabetes, specialized care is crucial. Denver Eye Surgeons provides tailored diabetic eye care, addressing cataracts and other complications related to diabetes. Their approach ensures your vision is protected while addressing the unique challenges posed by the condition.
By staying on top of chronic health issues with proper medication, a healthy lifestyle, and regular exercise, you not only reduce cataract risk but also improve early detection of potential problems.
The Importance of Regular Eye Exams
Routine eye exams are essential for catching cataracts – and other eye conditions – early. The American Academy of Ophthalmology suggests that adults between 40 and 64 without risk factors should get an eye exam every 2–4 years. After age 65, exams should increase to every 1–2 years. If you have diabetes, a family history of eye disease, or other risk factors, more frequent checkups may be necessary.
These exams help your eye doctor detect changes in your lens before symptoms become noticeable, giving you the opportunity to take action early and plan for treatment if needed.
Consider this: over 24.4 million Americans aged 40 and older have cataracts, and by age 75, about half of all Americans are affected. These numbers highlight just how critical regular eye care is.
At Denver Eye Surgeons, you can schedule comprehensive eye exams at least once a year to ensure your vision stays on track. Their skilled team is equipped to diagnose and manage cataracts at every stage, and with same-day appointments available, you won’t have to wait if you notice changes in your vision.

Shielding your eyes from UV rays is a key measure – wear sunglasses with UV protection and consider a wide-brimmed hat when outdoors. Eating a balanced diet full of antioxidants, such as vitamins C and E found in fruits and vegetables, is another way to promote eye health. It’s also wise to steer clear of smoking and limit alcohol intake, as both are linked to a higher likelihood of cataracts.
Don’t underestimate the importance of regular eye exams. These check-ups can help catch cataracts early and manage them effectively. If you’ve noticed changes in your vision, Denver Eye Surgeons provides thorough eye care and expert cataract treatment, offering personalized guidance tailored to your needs.
How are cataracts different from glaucoma or macular degeneration?
Cataracts, glaucoma, and macular degeneration are all eye conditions that can affect your vision, but they do so in distinct ways. Cataracts cause the eye’s natural lens to become cloudy, leading to blurry or dim vision. This condition typically develops gradually as part of the aging process. Glaucoma, however, is linked to increased pressure within the eye, which can damage the optic nerve. If left untreated, it can lead to peripheral vision loss. Meanwhile, macular degeneration targets the central part of your vision, making it difficult to see fine details or recognize faces.
If you’ve noticed changes in your vision, it’s essential to consult an eye care professional as soon as possible. For those in Denver, Denver Eye Surgeons provides specialized care and advanced treatments for cataracts, glaucoma, and other eye conditions to help safeguard and improve your vision.
What happens during cataract surgery, and how long does it take to recover?
Cataract surgery is a straightforward and safe procedure that involves replacing the cloudy lens in your eye with a clear artificial lens. It’s typically performed on an outpatient basis and usually takes just 15 to 30 minutes per eye. Most people feel little to no discomfort during the process.
After surgery, it’s normal to experience mild irritation or blurry vision for a few days as your eye begins to heal. While full recovery can take a few weeks, many patients notice their vision improving within just a day or two. To ensure proper healing, it’s important to follow your doctor’s post-surgery instructions, such as using prescribed eye drops and avoiding heavy lifting or intense physical activities. For those in the Denver area, the skilled professionals at Denver Eye Surgeons offer personalized cataract care to help restore your vision.
