Cataracts are a common eye condition that affects millions of people worldwide. They occur when the lens of the eye becomes cloudy, leading to blurred vision and, if left untreated, can eventually cause blindness. But what exactly causes cataracts, and how can we prevent them?

What Are Cataracts?

The lens of the eye is a transparent structure that focuses light onto the retina, allowing us to see clearly. When proteins in the lens clump together, they form cloudy areas known as cataracts2. This cloudiness can interfere with the passage of light, leading to blurred vision and difficulty seeing.

Causes of Cataracts

Several factors contribute to the development of cataracts:

Aging: As we age, the proteins in the lens naturally break down and clump together, leading to cataract formation.
UV Exposure: Prolonged exposure to ultraviolet (UV) light from the sun can damage the lens over time.
Diabetes: People with diabetes are at a higher risk of developing cataracts due to high blood sugar levels.
Smoking: Smoking increases oxidative stress, which can damage the lens.
Nutrition: Poor nutrition, particularly a lack of antioxidants like vitamins C and E, can contribute to cataract formation.

Molecular Mechanism of Cataract
Cataract formation is primarily driven by the aggregation of lens proteins, which disrupts the normal structure and function of the lens. This aggregation can be triggered by various factors, including aging, oxidative stress, and genetic mutations1. Oxidative stress, in particular, plays a significant role in cataract development, as it leads to the production of reactive oxygen species (ROS) that damage lens proteins and other cellular components.
