The main impact of cataracts on health is impaired vision, which can interfere with daily activities such as reading, driving, and recognizing faces. Over time, untreated cataracts can significantly reduce a person's quality of life and independence. It is essential to address cataracts promptly to prevent further deterioration of vision and maintain overall well-being.

Types of Cataracts
There are different types of cataracts based on where they form in the eye or how they develop, influencing vision in various ways.
- Nuclear Cataracts: Form in the center (nucleus) of the lens, often associated with aging.
- Cortical Cataracts: Develop in the lens cortex (outer layer), progressing from the edges towards the center.
- Posterior Subcapsular Cataracts: Occur at the back of the lens, affecting vision in bright light and causing glare.
- Congenital Cataracts: Present at birth or develop during childhood due to genetic factors or maternal infections.
- Traumatic Cataracts: Result from eye injuries, disrupting the lens clarity and vision.
Risk Factors

Treatment for Cataracts
Cataracts are typically treated through various safe and effective methods that aim to restore clear vision.
- Surgery: The most common treatment for cataracts is surgery to remove the cloudy lens and replace it with an artificial lens to restore vision.
- Prescription Glasses: In the early stages of cataracts, prescription glasses may help improve vision by compensating for the clouding of the natural lens.
- Change in Lifestyle: Making lifestyle changes such as quitting smoking, protecting the eyes from UV rays, and eating a healthy diet rich in antioxidants can slow the progression of cataracts.
- Eye Drops: Some eye drops may help manage symptoms of cataracts, such as dry eyes or discomfort, but they cannot reverse the condition or prevent its progression.
- Regular Eye Exams: Regular eye exams are essential for early detection of cataracts, allowing for timely intervention and appropriate management to preserve vision.
