Which symptom is most commonly associated with cataracts?

Cloudy vision is the most commonly associated symptom of cataracts because cataracts cause a progressive opacification of the lens of the eye. This cloudiness can lead to blurred or hazy vision, making it difficult to see clearly, particularly in low light or when looking at bright lights. As cataracts develop, they interfere with the passage of light through the lens, which is essential for clear vision. Patients may describe their vision as appearing as if they are looking through a foggy window or that colors seem less vibrant.

While other symptoms such as red eyes can occur due to various eye conditions, they are not specifically linked to cataracts. Severe pain is not a common symptom of cataracts; rather, cataracts typically involve visual changes without accompanying pain. Blindness can be a severe outcome in advanced cases of cataracts, but it is not immediate or direct; cloudy vision is the first noticeable symptom that patients report. Understanding this helps in recognizing cataracts early and seeking appropriate treatment.
