Definitions
- the invention relates to a progressive spectacle lens with little change of the binocular performance 'at a glance movement according to the preamble of claim 1.
- Progressive spectacle lenses are usually understood to mean spectacle lenses which, in the area through which the spectacle wearer looks at an object located at a greater distance - i.f. referred to as the far part - have a different (lower) refractive power than in the area (near part) through which the spectacle wearer looks at a near object.
- the so-called progression zone is arranged between the far part and the near part, in which the effect of the spectacle lens increases continuously from that of the far part to that of the near part.
- the value of the increase in impact is also referred to as addition.
- the distant part is arranged in the upper part of the spectacle lens and is designed for gazing "to infinity", while the near part is arranged in the lower region and is especially designed for reading.
- - pilot glasses or glasses for VDU places - the long-distance and the near part can also be arranged differently and / or be designed for other distances. It is also possible that there are several near parts and / or several distant parts and corresponding progression zones.
- the increase in the refractive power between the far part and the near part requires that the curvature of one or both surfaces changes continuously from the far part to the near part.
- the main curvature radii together with the refractive index n of the glass material determine the sizes that are often used for the optical characterization of a surface:
- Refractive index D 0.5 * (n-1) * (1 / Rl + 1 / R2)
- Area astigmatism A (n-1) * (1 / Rl - 1 / R2)
- the surface refractive index D is the size over which the increase in the effect from the far part to the near part is achieved.
- the area astigmatism A (clearly cylindrical effect) is a "disturbing property", since an astigmatism - unless the eye itself has an astigmatism to be corrected - that exceeds a value of approx. 0.5 dpt, leads to an image on the retina that is perceived as out of focus.
- the spectacle lens has different nasal and temporal properties at corresponding viewing points. This can impair binocular vision in particular. This is particularly noticeable when looking at the eye and is therefore annoying:
- the invention has for its object to develop a progressive spectacle lens according to the preamble of claim 1 such that the optical quantities relevant to the quality of the binocular visual impression change as little as possible during eye movements.
- the binocular properties relevant to the solutions to the problem are the astigmatic difference, the refractive equilibrium and the vertical prism difference.
- the astigmatic deviation and the refraction error of the wavefront through the left lens are combined with the values of the right lens and thus result in the sizes of the astigmatic difference (according to the method of crossed cylinders) and refraction equilibrium (absolute amount of the difference in the mean effect of the lenses).
- the vertical prism difference is obtained by projecting the main rays on the eye side into the Cyclops eye plane and expressing the angle between the straight lines in cm / m.
- Fig. 2 shows a comparison of the stroke of the refraction equilibrium (dpt) with horizontal eye movement
- Fig .3 shows a comparison of the stroke of the vertical
- the coordinate system used has its origin in the apex of the lens on the object side, and the z axis points in the direction of light.
- the abscissa values are the arithmetic mean of the x coordinates of the first and last penetration point of the main rays through the front surface of the glass.
- the ordinate values represent the strokes during the individual movements described.
- the stroke of the refraction equilibrium (difference in the mean effect of the lenses) is also significantly smaller in the entire horizontal section than in the competition. Nowhere does it exceed 0.06 dpt.
- the smaller change in the stroke of the vertical prism difference imaging properties is clearly shown in the subject of this invention, which does not exceed a value of .02 cm / m up to an x-coordinate of ⁇ 10 mm.
- the progressive spectacle lens according to the invention is thus characterized in that the change in the binocular imaging properties during horizontal eye movements is as small as possible and the associated binocular visual comfort is great.
- the progressive spectacle lens according to the invention can be calculated in particular in the so-called use position; a (concrete) usage situation is defined for this. This refers either to a specific user, for whom the individual parameters in the respective usage situation are determined and the progressive area is calculated and manufactured separately, or to average values as described in DIN 58 208 Part 2.
