What is a characteristic of a plus lens?

• A. It diverges light
• B. It converges light
• C. It does not affect light
• D. It absorbs light

Answer: (B)

A plus lens is designed to converge light rays that pass through it. This characteristic occurs because a plus lens, which is thicker in the center than at the edges, causes incoming parallel light rays to bend towards a focal point on the opposite side of the lens. This is a fundamental property of convex lenses, which are classified as plus lenses and are commonly used to correct hyperopia (farsightedness) by bringing light rays closer together to focus them correctly on the retina. The other options do not accurately describe the behavior of a plus lens; for instance, a lens that diverges light would be a minus lens, which is used to treat myopia (nearsightedness) instead. Similarly, stating a lens does not affect light or absorbs light would not be correct in the context of the primary function of a plus lens, which is to manipulate light for proper vision correction.
