Objects farther than six meters from the eye are seen clearly without any effort to focus. Compare ametropia, hyperopia, myopia.The normal condition of the eye as regards refraction of light rays. When the muscles in the eyeball are completely relaxed, the focusing power is accurately adjusted for parallel rays, so that vision is perfect for distant objects.The normal condition of the eye in refraction in which, when the eye is at rest, parallel rays focus exactly on the retina."}
