D. Eyelid - Protects eye from dust, flies, rain, etc.

Explanation

To solve the question regarding which part of the eye is incorrectly matched with its function, we will analyze each option provided.

### Step-by-Step Solution:

1. **Identify the Parts of the Eye and Their Functions**:
- We need to look at the different parts of the eye mentioned in the options and their respective functions.

2. **Evaluate Each Option**:
- **Option 1: Iris** - The function is to control the amount of light entering the eye by adjusting the size of the pupil. This is a correct match.
- **Option 2: Pupil** - The function is described as the opening through which light enters the eye. This is also a correct match.
- **Option 3: Cornea** - The function is stated as forming the image of the object. This is an incorrect match. The cornea is primarily responsible for refracting light and protecting the eye, but it does not form the image; that function is primarily performed by the lens.
- **Option 4: Eyelid** - The function is to protect the eyes from dust, flies, and other particles. This is a correct match.

3. **Conclusion**:
- After evaluating all the options, the incorrect match is **Option 3: Cornea** with the function of forming the image of the object.

### Final Answer:
The part of the eye that is incorrectly matched with its function is **Cornea** (Option 3).
