| x-point | <radiobiology> Place where the poloidal magnetic field vanishes in such a way that two flux surfaces appear to cross, for example where the main plasma joins the divertor or between magnetic islands. Location where magnetic reconnection takes place. See: magnetic reconnection, divertors, O-point. (09 Oct 1997) |

| 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) |
