Overview of Cataracts

Cataracts refer to the clouding of the eye’s natural lens, which is located behind the iris and pupil. This clouding causes a gradual loss of vision and can lead to blindness if not treated. Cataracts typically develop slowly over time, and symptoms may not be noticeable at first. However, as the cataract progresses, symptoms may become more pronounced and include:

• Blurred vision
• Double vision
• Sensitivity to light and glare
• Difficulty seeing at night
• Seeing colors as faded or yellowed
• Needing brighter light for reading or other activities

Cataracts are most commonly associated with aging and are a natural part of the aging process. Other risk factors for cataracts include:

• Prolonged exposure to UV radiation from the sun or other sources
• Smoking
• Alcohol consumption
• Obesity
• Diabetes
• High blood pressure
• Family history of cataracts
• Previous eye injury or surgery

Cataracts can often be treated with surgery, which involves removing the clouded lens and replacing it with an artificial lens. Cataract surgery is generally considered safe and effective, and most people experience significant improvement in their vision following the procedure. In some cases, cataracts may be treated with prescription eyeglasses or contact lenses, but these options typically provide only temporary relief and do not address the underlying issue.
