When we look at an object, an inverted diminished image of an object is formed on the retina of our eye. However, we see objects upright and of the appropriate size. How does this happen?

Explanation

### Step-by-Step Solution:

1. **Understanding Image Formation**: When we look at an object, light rays from that object enter our eyes and are focused by the lens onto the retina, which acts like a screen. The image formed on the retina is inverted (upside down) and diminished (smaller than the actual object).

2. **Role of the Retina**: The retina contains photoreceptor cells that convert the light into electrical signals. This is where the inverted and diminished image is formed.

3. **Transmission to the Brain**: The electrical signals generated by the retina are transmitted to the brain via the optic nerve. The optic nerve carries visual information from the retina to the visual cortex in the brain.
