analyzing a phenomenon corrected by lenses\nwhat phenomenon causes the fuzzy image? what kind of lens is…

Brief Explanations:

If the fuzzy image is due to nearsightedness (myopia), light rays focus in front of the retina. A concave lens is used to correct it as it diverges the incoming light rays so that they focus correctly on the retina. If it's farsightedness (hyperopia), light rays focus behind the retina, and a convex lens is used to converge the light rays to focus on the retina. Without more specific information about the nature of the fuzziness, these are the general principles.

Answer:

If it's myopia: The phenomenon is light - rays focusing in front of the retina. A concave lens is used. It diverges the incoming light rays to make them focus on the retina. If it's hyperopia: The phenomenon is light - rays focusing behind the retina. A convex lens is used. It converges the incoming light rays to make them focus on the retina.
