that IS in of the retina. (a) With the +20 lens in your "eye" (in the water) and the light source 33 cm away from the cornea, notice that there is a sharp image on the retina. This represents the normal eye functioning properly. Now make the eye myopic by making the eyeball too long. Do this by moving the retina to its farthest rear position away from the lens. Describe what happens to the image on the retina when you do this.

Question
Transcribed Image Text:**Near-sightedness (myopia).** A near-sighted, or myopic, person can see nearby objects clearly but not distant ones. A common cause of myopia is an eyeball that is *too long*. In that case, the properly-functioning lens forms an image where the retina *should* be, so the image is formed *before* the light reaches the retina, meaning that it is in front of the retina.
