Answer

The question describes a condition where the eye lens becomes cloudy, leading to a gradual loss of vision. This condition is known as cataract.

### Step-by-Step Solution:

1. **Identify the Condition**: The question states that the eye lens becomes cloudy. This is a key symptom of a specific eye condition.

2. **Understand the Implications**: When the eye lens becomes cloudy, it affects the way light enters the eye and is focused on the retina. This can lead to blurred vision and difficulty seeing clearly.

3. **Name the Condition**: The medical term for the clouding of the eye lens is "cataract." It is a common condition, especially in older adults, and can lead to significant vision impairment if not treated.

4. **Discuss Treatment Options**: Cataracts can be treated effectively through surgery, where the cloudy lens is removed and often replaced with an artificial lens. This procedure can restore clear vision.

5. **Preventive Measures**: While cataracts are often age-related, some preventive measures include protecting the eyes from UV light, maintaining a healthy diet rich in antioxidants, and avoiding smoking.

### Final Answer:
In cataract, the eye lens becomes cloudy, which leads to gradual loss of vision.
