| near point of convergence | The point to which the visual lines are directed when convergence is at its maximum. (05 Mar 2000) |
| 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. In very young people and in those with myopia, this distance is less. The near point recedes with age, possibly even causing farsighted condition,. (05 Aug 1998) |
| needle point tracing | A tracing of mandibular movements made by means of a device attached to the opposing arches; its shape resembles that of an arrowhead or a Gothic arch, and when the instrument's marking point is at the apex of the arch, the jaws are considered to be in centric relation. Synonym: arrow point tracing, Gothic arch tracing, Gothic arch, stylus tracing. (05 Mar 2000) |

| nodal point | One of two point's in a compound optical system so related that a ray directed toward the first point will appear to have passed through the second point parallel to its original direction. Synonym: axial point. (05 Mar 2000) |
| subnasal point | The centre of the root of the anterior nasal spine. Synonym: apophysary point, apophysial point, spinal point. (05 Mar 2000) |
