| near point of the eye | <ophthalmology> The nearest point to the entrance of the pupil of the normal eye at which focus is attained without strain, 10 inches (250 mm) is the generally accepted distance.

| near sight | <ophthalmology> That error of refraction in which rays of light entering the eye parallel to the optic axis are brought to a focus in front of the retina, as a result of the eyeball being too long from front to back (axial myopia) or of an increased strength in refractive power of the media of the eye (index myopia). Also called nearsightedness, because the near point is less distant than it is in emmetropia with an equal amplitude of accommodation. Origin: Gr. Myein = to shut (18 Nov 1997) |
