blur point
1. The point at which the fixation target appears blurred on the introduction of increasing prisms and/or lens power, as for example in a test for relative convergence. 2. A point on a graph representing the limit of clear, single, binocular vision. See relative convergence; binocular vision single zone of clear.
break point The point at which diplopia occurs when increasing prism or lens power during binocular fixation. See blur point; relative convergence.
cardinal point's Six points on the optical axis of a lens system or thick lens: the two principal foci, the two principal points and the two nodal points. (Sometimes, this definition also includes the axial object and image points.) (Fig. P14) Syn. gaussian points (some authors consider this term synonymous, although it does not include the two nodal points). See cardinal planes.
centration point The point at which the optical centre (of a lens) is to be located in the absence of a prescribed prism, or after any prescribed prism has been neutralized. If the centration point is not specified, it is located at the standard optical centre position (British Standard). See standard optical position centre; decentration.

neutral point 1. In retinoscopy, it is the point at which the sight hole of the retinoscope is conjugate with the patient's retina. At this point, no reflex motion can be seen by the examiner and the entire pupil is illuminated completely, or is completely dark. This is obtained in a myopic eye when the retinoscope is placed at the far point of accommodation. When testing emmetropes and hyperopes this neutral point is reached when sufficient converging lens power has been added in order to displace the far point (artificially) to the sight hole of the retinoscope. See conjugate distances.

See conjugate distances.
2. In dichromats, it is a region of the spectrum that appears colourless. See deuteranopia; protanopia; tritanopia.
nodal point's In a centred optical system they are a pair of conjugate points on the axis which have the property that any incident ray which passes through the first nodal point leaves the system as though from the second nodal point and parallel to the incident ray. Thus the refracted ray is unchanged in direction, although displaced. The distance between the two nodal points is equal to the distance between the two principal points. When the refractive indices on each side of the system are equal, as in the case of a thick lens in air, the principal and nodal points coincide. They are then called equivalent points. In a single refracting surface, the nodal points coincide with the centre of curvature, while the principal points coincide with the vertex of the surface (Figs. P12 and P14). See optical centre; principal plane; vertex.
null p . See nystagmus.
point object See point object.
principal point's The points of intersection of the principal planes with the optical axis. The principal points are the usual reference points from which the focal lengths and the object and image distances are measured (Figs. P12 and P14). See equivalent power.
recovery point The point at which fusion is regained on decreasing the prism or lens power which originally induced diplopia in investigation of relative accommodation and convergence. See relative convergence.
point of regard Usually a synonym of point of fixation. However, in some circumstances it may be a peripheral point in space upon which visual attention is directed, while the eye is looking foveally at a point of fixation. See point of fixation.
point source See point source.
visual point The point of intersection of the visual axis with the back surface of a spectacle lens (British Standard). See distance visual point; near visual point.
point zero A point on the retina of a strabismic eye which has acquired the same visual direction, under binocular conditions, as the fovea of the fixating eye.

Patient discussion about point
Q. what is the difference between tender points and trigger points. I read somewhere in the net that there are two points called tender and trigger points which are one of the symptoms of fibromyalgia. Is that true? If so what is the difference between tender points and trigger points?
A. What you have read about tender and trigger points are true. A tender point hurts to the touch and causes some degree of pain in that area, while a trigger point may not necessarily be painful to the touch but causes a degree of pain to be felt in another area. Fibromyalgia patients typically have a number of tender points and, according to the American College of Rheumatology, the diagnostic criteria for fibromyalgia stipulates that an FMS sufferer should have pain upon palpation (i.e. touch) in eleven of the generally accepted eighteen tender points. A tender point is verified in a physical examination in which approximately nine pounds of pressure are applied by touch and the patient acknowledges that pain is felt.
Q. can Autism appears in any point in life?
A. not really no, ether you diagnose it at the age of 3 or it's not there.
Q. My aunty who is suffering from fibromyalgia feels the position of painful tender/trigger points moves. My aunty who is suffering from fibromyalgia feels the position of painful tender points /trigger points moves. The pain moves. For this reason, pain cannot be bound to specific points. Can anybody help?
A. It’s a usual feeling faced by most. Really you will get more help from this community. We recommend you to consider neurophysiology and neuropsychology which can help you to understand the problem and the quality of pathological inference and its central representation.
