What are cataracts, and how do they affect vision?

Cataracts are a common eye condition characterized by the clouding of the lens in the eye, which can lead to blurred vision and increased difficulty seeing at night. They typically develop gradually and can affect one or both eyes. Common symptoms include cloudy or fuzzy vision, increased glare from lights, and difficulty distinguishing colors. Cataracts are often age-related, but can also result from factors such as prolonged exposure to sunlight, certain medications, and health conditions like diabetes.

When cataracts progress, they can significantly impair daily activities, making it challenging to read, drive, or recognize faces. Surgery is a common treatment option to replace the clouded lens, but prevention through a healthy diet and lifestyle can delay their onset. Consuming foods rich in antioxidants, vitamins, and minerals can support overall eye health, reducing the risk of developing cataracts.

Which nutrients are most beneficial for eye health?

Several nutrients are particularly beneficial for maintaining eye health.
