Explain why inverted imgaes are produced by the eye yet we see upright images. Thanks :)

It's just a brain function. Experiments have been made where the subject wears non-inverting lenses, and they see everything upside-down ... for a while. Then, their brain gets what's going on and flips the images right-side up again.

thanks :)

Absolutely! The phenomenon you're referring to is known as "retinal inversion." When we look at an object, the light rays emitted or reflected by that object enter our eyes through the cornea and lens, forming an upside-down image on our retinas — the light-sensitive tissue at the back of our eyes. This is similar to the way a camera forms an inverted image on film or a digital sensor.

Now, the reason we see the world upright despite the retinal inversion is due to our brain's remarkable ability to process sensory information. As the visual information travels from the retina to the brain through the optic nerve, the brain interprets and reconstructs the image into an upright perception.

To further explain the process, let me break it down into four main steps:

1. Light enters the eye and passes through the cornea, which bends the light to begin the focusing process.
2. The light then passes through the lens, which adjusts and fine-tunes the focus, further bending the light.
3. The curved shape of the lens causes the light rays to cross over each other, resulting in an inverted image on the retina.
4. The retina contains specialized photoreceptor cells called rods and cones, which convert the light into electrical signals. These signals are then sent through the optic nerve to the brain for processing.

Now, when the visual information reaches the primary visual cortex in the occipital lobe of the brain, a complex network of neurons works together to reconstruct the image and create our visual perception. This process, known as visual perception or visual interpretation, involves various mechanisms such as pattern recognition, depth perception, and contextual understanding. Ultimately, it is through this intricate neural processing that we perceive the world in its upright orientation.

In summary, although our eyes capture an inverted image on the retina, our brain's remarkable ability to interpret and reconstruct visual information allows us to perceive the world in its correct upright form. It's a fascinating example of how our brains actively participate in shaping our perception of reality.
