6 Signs You May Have Cataracts


Cataracts are a common eye condition as people age. They occur when the eye’s natural lens becomes cloudy, leading to vision problems. Early detection is key to managing cataracts effectively and preserving your vision. Understanding the signs of cataracts can help you seek timely medical advice. This blog discusses six common signs that may indicate the presence of cataracts. By being aware of these symptoms, you can take proactive steps to protect your eye health.

1. Causes of Cataracts

The answer to what causes cataracts is not simple, as they develop due to various factors. Aging is the most significant cause. As people age, the proteins in the eye’s lens can clump together, creating cloudy areas that impair vision. Other contributing factors include excessive exposure to ultraviolet (UV) radiation, smoking, and excessive alcohol consumption. Certain medical conditions like diabetes and prolonged use of corticosteroid medications can increase the risk of cataracts. If you have a family history of cataracts, you may be more likely to develop them. Eye injuries and previous eye surgeries can also lead to cataracts.

2. Blurry or Cloudy Vision

One of the most common signs of cataracts is blurry or cloudy vision. This symptom occurs as the lens of the eye becomes increasingly opaque, scattering light and making it difficult to see clearly. You might see your vision is like looking through a foggy window. This can affect your ability to perform everyday tasks such as reading, driving, or recognizing faces. Blurry or cloudy vision typically worsens over time as the cataract progresses. This symptom can develop in one or both eyes, and it may not be symmetrical. If you experience persistent blurry vision that does not improve with glasses or contact lenses, consult an eye care professional.

3. Difficulty Seeing at Night

Another sign of cataracts is having difficulty seeing at night. Cataracts can make it harder to see in low-light conditions. You might find it challenging to drive at night, as oncoming headlights and streetlights create glare and halos, making it difficult to see the road. Difficulty seeing at night can also affect other activities, such as walking in poorly lit areas or reading in dim light. If you notice that your night vision is deteriorating, it could be an indication of developing cataracts. An eye examination can help determine the cause of your night vision problems and allow for appropriate treatment to improve your overall vision quality.

4. Sensitivity to Light and Glare

Increased sensitivity to light and glare is another common symptom of cataracts. Bright sunlight, indoor lighting, and headlights can cause discomfort and make it difficult to see. You might find yourself squinting or needing to wear sunglasses more frequently to reduce the glare. This can interfere with your daily activities and reduce your quality of life. Sensitivity to light and glare occurs because cataracts cause the lens to scatter light entering the eye, creating glare and reducing contrast. If you experience these symptoms, seek an eye examination to determine the cause. Proper diagnosis and treatment can help alleviate the discomfort associated with light sensitivity and improve your vision.

5. Frequent Changes in Prescription Glasses or Contact Lenses

If you find that your prescription for glasses or contact lenses is changing more frequently than usual, it could be a sign of cataracts. As cataracts develop, they can cause fluctuations in your vision. You might notice that your current glasses or contact lenses no longer provide clear vision. These frequent changes can be frustrating and costly. It’s important to monitor how often you need to update your prescription and discuss these changes with your eye care professional. If cataracts are the underlying cause, addressing them through appropriate treatment can stabilize your vision and reduce the need for frequent prescription changes.

6. Fading or Yellowing of Colors

Cataracts can cause colors to appear faded or yellowed. This symptom occurs because the cloudy lens filters and scatters light, leading to a dull and discolored perception of the world around you. You might notice that whites appear more yellow and bright colors look less intense. This can impact activities that rely on color differentiation, such as cooking, choosing clothing, or engaging in creative projects. Fading or yellowing of colors can also make everyday tasks less enjoyable. If you experience changes in how you perceive colors, have your eyes examined.


Recognizing the signs of cataracts early can help you seek timely medical advice and treatment. Blurry or cloudy vision, difficulty seeing at night, and increased sensitivity to light and glare are common indicators. Frequent changes in prescription glasses or contact lenses and the fading or yellowing of colors can also signal the presence of cataracts. Understanding the causes of cataracts, such as aging, UV exposure, and certain medical conditions, can help you take preventive measures. If you notice any of these symptoms, schedule an eye examination to determine the cause and discuss treatment options.
