Final Jeopardy 1.What happens in the eye of a person who is nearsighted? Explain what causes the person’s vision to be blurry. Explain how the eye would work if it were normal. What is different about the nearsighted eye? Use the terms cornea, lens, retina, and focal point in your response.

Final Jeopardy Answer In a normal eye, the cornea and lens work together to focus light. The focal point is in a position so that the image is focused on the retina. In a nearsighted eye, the shape is distorted, so the imagle is focused in front of the retina.
