Emmetropia refers to a state of normal vision where light rays entering the eye are focused precisely on the retina without the need for corrective lenses. This means that individuals with emmetropic eyes can see clearly at various distances, as the refractive power of their eye is perfectly matched to the length of the eyeball. Therefore, all rays of light are appropriately focused on the retina, allowing for optimal visual acuity.

The other options reflect different visual issues:

- The first choice implies a need for corrective lenses, which is contrary to the definition of emmetropia.

- The second choice suggests that light rays do not focus on the retina, indicating a refractive error like myopia or hyperopia, which emmetropia does not represent.

- The final choice claims that vision is impaired for distance viewing, which also does not relate to emmetropia, as this condition denotes having no such impairment.
