Introduction
With the rise in screen time, environmental pollutants, and aging populations, eye health has become a major concern worldwide. Cataracts, a leading cause of blindness, affect millions of people annually. Prevention is key, and vitamins play a crucial role in maintaining good vision and reducing the risk of cataracts.
In 2025, advancements in nutrition and research continue to highlight the best vitamins and nutrients that support optimal eye health. This article explores the top vitamins for cataract prevention, their benefits, and the best food sources or supplements available.
Understanding Cataracts and Their Causes
What Are Cataracts?
A cataract is the clouding of the eye’s lens, leading to blurry vision, sensitivity to light, and difficulty seeing at night. It typically develops due to aging, but other factors such as genetics, UV exposure, smoking, diabetes, and poor nutrition contribute to its formation.
What Causes Cataracts?
- Aging: The most common cause; proteins in the lens break down over time.
- Oxidative Stress: Free radicals damage lens proteins, causing clouding.
- UV Exposure: Sunlight contributes to lens damage.
- Nutrient Deficiency: Lack of essential vitamins accelerates eye aging.
- Smoking & Alcohol Consumption: Increase oxidative damage.
- Diabetes & Hypertension: Contribute to cataract formation.
Prevention through proper nutrition is one of the best strategies to maintain clear vision and reduce the risk of cataracts.
