D. inverted.

Answer

To solve the question "When we see an object, the image formed on the retina is...", we need to analyze the functioning of the human eye and the properties of the image formed by it.

### Step-by-Step Solution:

1. **Understanding the Eye Structure**:
- The human eye consists of several parts, including the cornea, lens, and retina. The lens of the eye focuses light onto the retina.

2. **Image Formation**:
- When light from an object enters the eye, it passes through the cornea and the lens. The lens focuses the light rays to form an image on the retina.

3. **Retina as the Image Plane**:
- The retina acts as a screen where the image of the object is formed. This image is what the brain interprets as the visual representation of the object.

4. **Constant Parameters**:
- The distance from the lens of the eye to the retina remains constant. This distance is crucial because it ensures that the image is always formed on the retina, regardless of the distance of the object being viewed.

5. **Conclusion**:
- Therefore, when we see an object, the image formed on the retina is always at a fixed distance from the eye lens, which is the distance to the retina.

### Final Answer:
The image formed on the retina is at a constant distance from the eye lens.
