Question: 1 / 50

How can plus lenses be characterized?

the radius of curvature of a one diopter lens

simple myopia or nearsightedness can be corrected with these type of lenses

plus spheres are used for farsightedness

plus lenses can be characterized by converging/against motion

Plus lenses can be characterized by their ability to converge light, making objects appear larger and closer. This characterizes their use for correcting farsightedness, which is when objects appear blurry when near due to the eye not being able to focus properly. The other options are incorrect because A refers to the curvature of the lens, B refers specifically to myopia while plus lenses are used for correcting hyperopia (farsightedness), and C is similar to D but does not accurately describe the purpose of plus lenses.
