A converging lens is designed to focus incoming parallel rays of light, which typically come from distant objects, to a single focal point. This type of lens has a thicker middle section and is rounded at the edges, which allows it to bend the light rays inward as they pass through. The curvature of the lens is crafted in such a way that it causes the light rays to converge at that focal point, thus producing a clear image of distant objects.

In contrast, a diverging lens spreads out light rays that are entering the lens, causing them to diverge rather than focusing them. Plano-convex lenses also primarily focus light but may not be specifically designed for distant light like a standard converging lens. Cylindrical lenses, while useful for correcting specific visual impairments, have a different design that focuses light in only one direction rather than converging light to a single point in two dimensions. This makes the converging lens the appropriate choice for focusing distant light effectively.
