Myopia means that the curvature of the lens becomes larger and the convergence ability is enhanced, that is, the refractive power is enhanced. The image appears in front of the retina, so wear divergent lenses to delay the convergence of light. For hyperopia, the convergence ability is weakened because the curvature of the lens becomes smaller, that is, the refractive ability is weakened, and the image appears behind the retina, so the convergence lens should be worn.

So the answer is: ③, ①.
