摘要： PROBLEM TO BE SOLVED: To provide spectacles in which wearing person can obtain a substantially constant of field of view of object in near visual acuity part regardless of non-emmetropia or power addition value of lens and without leading to the deterioration of lens characteristics. SOLUTION: The surface of the ophthalmic lens has a far visual acuity part VL containing a control point L for far visual acuity, a near visual acuity part VP containing a control point P for near visual acuity, an intermediate visual acuity part VI between the far visual acuity part VL and the near visual acuity part VP, and a progressive main diameter line MM' passing three parts of the far visual acuity part VL, the near visual acuity part VP and the intermediate visual acuity part VI. This ophthalmic lens has a power addition value defined as the deviation in the average spherical surface between the far visual acuity control point L and the near visual acuity control point P, and a base defined as the value of the average spherical surface in the far visual acuity control point L.

摘要： Apparatus for determining the diameter of an unprocessed ophthalmic lens to fit a particular eyeglass frame comprises a base and a guide on the base adapted to receive a card carrying diagrams of available lenses. A support on the base is adapted to receive the eyeglass frame to be fitted with lenses. The card guide is fixed relative to the base and comprises an elongate slot adapted to allow the card to slide within it. The frame support is mobile relative to the card guide in the direction at right angles to the slot.

摘要： PURPOSE: To provide a device for engaging holding parts with spectacle lenses, where the spectacle lenses are prevented from falling and being broken owing to the interference of an arm with the holding parts. CONSTITUTION: The device which is arranged in a plate so as to fix the holding parts to the spectacle lenses is provided with one arm 13 receiving the holding parts so as to be rotation possible and a carriage for permitting the arm 13 to rotate between a lifting load end position and lowering engagement end position. The carriage can straightly move between a drawing halt position and the advance end of a movement position. In a transmitting device which is operated between a driving device and one of the arm 13 or the carriage, the arm 13 is located at a drawing engagement position when the carriage is located at least at the position being adjacent to the advance end of the movement position. A restraining device is operated between the arm 13 and the carriage and permits the arm 13 to be restrained to the carriage at a lowering halt position in terms of a liberation.

摘要： PURPOSE: To enable engaging holding part by means of force added to a lens without permitting the lens to be broken by constituting a system by means of a plate, a calibration spring device and a displacement sensor. CONSTITUTION: The plate 11 for receiving spectacle lenses is pivotally attached to a fixing base 15 so as to be freely rotation possible and the calibration spring device 16 and the displacement sensor 18 are operated between the plate 11 and the fixing base 15. That is, when the plate 11 is rotated with an axis A2 as a center by engagement force added along an engagement axis A1 , the plate 11 is moved downwards and a proper calibration is executed by the calibration spring device 16. The spring device 16 normally permits the plate 11 to be brought into pressure-contact with the abutting part 34 of the base 15 in order to correctly fix a halt position. Then, the feeler 36 of the displacement sensor 18 covers an optical battery 35 so that a driving device for engaging the holding parts with the spectacle lenses 12 arranged in the plate 11 is operated.

摘要： PURPOSE: To provide a relatively light-weight ophthalmologic lens with a large diameter having a positive refractive power by making the diameter of a central optical working area almost equal to the diameter of the geometrical outline of the lens, and having a special relation with the refractive power. CONSTITUTION: A diameter D1 of the central optical working area 10 of a lens is made almost equal to a diameter D2 of a geometrical outline 11. Then, a peripheral blending area 12 is provided between the optical working area and the geometrical outline 11 in the surrounding of the optical working area. In this case, a diameter D1 mm and a refractive power P diopter are related with each other in order to fulfill an expression D1 =a.b.P. Here, the values of a=84-89, and b=4-9 are used. Thus, the positive reflective power P=2-9 can be attained, and the relatively light opthalomological lens with a large diameter can be obtained.

摘要： PURPOSE: To attain the suitable correction of astigmatism and field curvature by constituting a single focus lens having partially spherical convex and concave faces so that the refractive index is changed from the optical axis of the lens to its periphery and optical magnification is regulated only by the refractive index independently of geometric magnification. CONSTITUTION: The single focus lens for glasses has partially spherical concave and convex faces 11, 10, changes its refractive index from the optical axis X of the lens to the periphery and regulates the optical magnification only by the refractive index independently of geometric magnification. Thus, the use of the concave and convex faces 11, 10, fixed thickness and the merits of fine picture quality are suitably combined. Consequently, the single focus glasses lens allowed to be easily worked and capable of sufficiently correcting astigmatism and field curvature aberration and suitably reducing the thickness of the center part or the peripheral part is manufactured.

摘要： PURPOSE: To automatically measure the inter-pupil distance of a human by forming an instrumentation coordinate system with a series of reference light sources linearly arranged according to regular pitches, and reading the existence of multiple cornea reflected rays via its scanning. CONSTITUTION: Reference light sources 28 form parallel luminous segments. Basic light sources 16 generate cornea reflected rays in sequence. The cornea reflected rays processed by a detecting acceptor 20 are generated by the basic light source 16 nearest to the general visual line directions DO, DG of corresponding eyes OD, OG. For the measurement of half inter-pupil distances ED, EG in relation to the general visual line direction D with a conversion table, the cornea reflected rays formed along the visual line directions DO, DG parallel with the visual line direction D in relation to the reference light sources 28 are positioned. Peaks TD, TG corresponding to the cornea reflected ray by the right eye OD and the cornea reflected ray by the left eye OG appear on a cornea reflected ray generator 12. The positions of the peaks TD, TG can be obtained by a trigonometrical calculation.
