@Arunan **It’s all done by the brain.** The eye is just a sensor. Making sense of what is sensed is the job of the processor - the brain. In addition to inverting the image on the retina, the brain is also able to combine the images from the two eyes to give us the perception of depth. In fact, this processing is not passive. That is, the brain does not just take the image from the eye and invert it. If the input to the eye is altered over a sufficiently long period of time, the brain is able to compensate for it. This is known as [perceptual adaptation](https://en.wikipedia.org/wiki/Perceptual_adaptation) > **[Neural adaptation](https://en.wikipedia.org/wiki/Neural_adaptation)** > > Neural adaptation or sensory adaptation is a gradual decrease over time in the responsiveness of the sensory system to a constant stimulus. It is usually experienced as a change in the stimulus. For example, if a hand is rested on a table, the table's surface is immediately felt against the skin. Subsequently, however, the sensation of the table surface against the skin gradually diminishes until it is virtually unnoticeable. The sensory neurons that initially respond are no longer stimulated to ... you can learn more about [perceptual adaptation](https://en.wikipedia.org/wiki/Perceptual_adaptation) from the link 👆 --- _[View the full topic](https://metastudio.org/t/homemade-solar-eclipse-viewer/4121)._
