A person suffering from far-sightedness, also known as hypermetropia, will use convex or converging lenses in their spectacles. Here are the steps to explain why:

1. Far-sightedness is a common vision condition where a person can see distant objects clearly, but objects nearby may be blurry. This happens when the light entering the eye focuses behind the retina, instead of directly on it.

2. The purpose of the spectacle lens is to redirect the light so that it focuses directly on the retina, which will make the vision clear.

3. Convex lenses are thicker in the middle and thinner at the edges. When light passes through a convex lens, it is bent towards the center. This causes the light rays to converge or come together.

4. By wearing spectacles with convex lenses, a far-sighted person can correct their vision. The lens will bend the incoming light rays so that they focus directly on the retina, allowing the person to see nearby objects clearly.

5. The power of the convex lens needed will depend on the degree of far-sightedness. An optometrist will be able to determine the correct lens power during an eye examination.
