Demonstration of near and far sightedness. Focus camera on a page about 30cm from the camera. When the page is removed the objects in the distance are not in focus, near sightedness. This can be corrected with a diverging lens.
Focus the camera on the distant object and then place a page at a reading distance, 30 cm. The page will be out if focus and it can be corrected with a converging lens, far sightedness.
Location: I2-3, you will also need a computer and display to show what the “eye” sees.
