Definitions
- the invention relates to a lens element intended to be worn in front of an eye of a person to suppress progression of abnormal refractions of the eye such as myopia or hyperopia.
- Myopia of an eye is characterized by the fact that the eye focuses distant objects in front of its retina. Myopia is usually corrected using a concave lens and hyperopia is usually corrected using a convex lens.
- Such focusing defect may have an impact on the progression of myopia of such individuals.
- Foveal vision corresponds to viewing conditions for which the image of an object looked at is formed by the eye in the central zone of the retina, called the foveal zone.
- Peripheral vision corresponds to the perception of elements of a scene that are offset laterally relative to the object looked at, the images of said elements being formed on the peripheral area of the retina, away from the foveal zone.
- the ophthalmic correction with which an ametropic subject is provided is usually adapted for his foveal vision.
- the correction has to be reduced for the peripheral vision relative to the correction that is determined for the foveal vision.
- studies carried out on monkeys have shown that strong defocusing of the light behind the retina, which occurs away from the foveal zone, may cause the retina of the eye to extend and therefore may cause a myopia defect to increase.

- a progressive lens comprises at least one but preferably two non-rotationally symmetrical aspheric surfaces, for instance but not limited to, progressive surface, regressive surface, toric or atoric surfaces.
- a minimum curvature CURVmin is defined at any point on an aspherical surface by the formula:
- Rmax is the local maximum radius of curvature, expressed in meters and CURVmin is expressed in dioptres.
- a maximum curvature CURVmax can be defined at any point on an aspheric surface by the formula:
- Rmin is the local minimum radius of curvature, expressed in meters and CURVmax is expressed in dioptres.
- the local minimum radius of curvature Rmin and the local maximum radius of curvature Rmax are the same and, accordingly, the minimum and maximum curvatures CURVmin and CURVmax are also identical.
- the local minimum radius of curvature Rmin and the local maximum radius of curvature Rmax are different.
- the minimum and maximum spheres labeled SPHmin and SPHmax can be deduced according to the kind of surface considered.

- any aspherical face of the lens may be expressed by the local mean spheres and cylinders.
- a surface can be considered as locally non-spherical when the cylinder is at least 0.25 diopters.
- a local cylinder axis gAC may further be defined.
- Figure 7a illustrates the astigmatism axis g as defined in the TABO convention and figure 7b illustrates the cylinder axis gAC in a convention defined to characterize an aspherical surface.
- the cylinder axis gAC is the angle of the orientation of the maximum curvature CURVmax with relation to a reference axis and in the chosen sense of rotation.
- the reference axis is horizontal (the angle of this reference axis is 0°) and the sense of rotation is counter clockwise for each eye, when looking at the wearer (0° ⁇ gAC ⁇ 180°).
- An axis value for the cylinder axis gAC of +45° therefore represents an axis oriented obliquely, which when looking at the wearer, extends from the quadrant located up on the right to the quadrant located down on the left.
- a progressive multifocal lens may also be defined by optical characteristics, taking into consideration the situation of the person wearing the lenses.
- Figures 8 and 9 are diagrammatic illustrations of optical systems of eye and lens, thus showing the definitions used in the description. More precisely, figure 8 represents a perspective view of such a system illustrating parameters a and b used to define a gaze direction. Figure 9 is a view in the vertical plane parallel to the antero posterior axis of the wearer’s head and passing through the center of rotation of the eye in the case when the parameter b is equal to 0.
- the center of rotation of the eye is labeled Q’.
- the axis Q’F’ shown on Figure 9 in a dot-dash line, is the horizontal axis passing through the center of rotation of the eye and extending in front of the wearer - that is the axis Q’F’ corresponding to the primary gaze view.
- This axis cuts the aspherical surface of the lens on a point called the fitting cross, which is present on lenses to enable the positioning of lenses in a frame by an optician.
- the point of intersection of the rear surface of the lens and the axis Q’F’ is the point O. O can be the fitting cross if it is located on the rear surface.
- An apex sphere, of center Q’, and of radius q’ is tangential to the rear surface of the lens in a point of the horizontal axis.
- a value of radius q’ of 25.5 mm corresponds to a usual value and provides satisfying results when wearing the lenses.
- a given gaze direction - represented by a solid line on figure 8 - corresponds to a position of the eye in rotation around Q’ and to a point J of the apex sphere; the angle b is the angle formed between the axis Q’F’ and the projection of the straight line Q’J on the horizontal plane comprising the axis Q’F’; this angle appears on the scheme on Figure 3.
- the angle a is the angle formed between the axis Q’J and the projection of the straight line Q’J on the horizontal plane comprising the axis Q’F’; this angle appears on the scheme on Figures 8 and 9.
- a given gaze view thus corresponds to a point J of the apex sphere or to a couple (a, b). The more the value of the lowering gaze angle is positive, the more the gaze is lowering and the more the value is negative, the more the gaze is rising.
- the image of a point M in the object space, located at a given object distance, is formed between two points S and T corresponding to minimum and maximum distances JS and JT, which would be the sagittal and tangential local focal lengths.
- the image of a point in the object space at infinity is formed, at the point F’ .
- the distance D corresponds to the rear frontal plane of the lens.
- Ergorama is a function associating to each gaze direction the usual distance of an object point. Typically, in far vision following the primary gaze direction, the object point is at infinity. In near vision, following a gaze direction essentially corresponding to an angle a of the order of 35° and to an angle b of the order of 5° in absolute value toward the nasal side, the object distance is of the order of 30 to 50 cm.
- US patent US-A-6,318,859 may be considered. This document describes an ergorama, its definition and its modeling method. For a method of the invention, points may be at infinity or not. Ergorama may be a function of the wearer’s ametropia or wearer’s addition.
- An object point M at an object distance given by the ergorama is considered for a gaze direction (a,b).
- An object proximity ProxO is defined for the point M on the corresponding light ray in the object space as the inverse of the distance MJ between point M and point J of the apex sphere:
- the object proximity can be considered as the inverse of the distance between the object point and the front surface of the lens, on the corresponding light ray.
- the image of a point M having a given object proximity is formed between two points S and T which correspond respectively to minimal and maximal focal distances (which would be sagittal and tangential focal distances).
- the quantity Proxl is called image proximity of the point M:
- an optical power Pui as the sum of the image proximity and the object proximity.
- an astigmatism Ast is defined for every gaze direction and for a given object proximity as :
- This definition corresponds to the astigmatism of a ray beam created by the lens. It can be noticed that the definition gives, in the primary gaze direction, the classical value of astigmatism.
- the astigmatism angle is the angle g.
- the angle g is measured in the frame ⁇ Q’ , xm, ym, zm ⁇ linked to the eye. It corresponds to the angle with which the image S or T i formed depending on the convention used with relation to the direction zm in the plane ⁇ Q’, zm, ym ⁇ .
- optical power and astigmatism have been defined for foveal vision considering the light ray passing by the center of rotation of the eye of the wearer.
- the optical power and astigmatism may be defined in a similar manner for peripheral vision considering the light ray passing by the center of the pupil of the wearer as illustrated on figure lOa.
- the prescription portion 12 may further be configured to provide to the wearer for foveal vision a second optical power for foveal vision different from the first optical power based on the prescription of the wearer.

- the“quadrants at 45°” are to be understood as equal angular quadrant of 90° oriented in the directions 45 225° and 1357315° according to the TABO convention as illustrated on figure 1.
- the central zone 16 comprises a framing reference point that faces the pupil of the wearer gazing straight ahead in standard wearing conditions and has a diameter greater than or equal to 4 mm and smaller than or equal to 22 mm.
- At least the lower part quadrant Q4 has a second optical power for central vision different from the first optical power corresponding to the prescription for correcting the abnormal refraction.
- the prescription portion has a progressive addition dioptric function.

- At least one of the temporal Q3 and nasal Ql quadrant has a second optical power.
- the temporal Q3 quadrant has a variation of power with the eccentricity of the lens.
- such configuration increases the efficiency of the abnormal refraction control in peripheral vision with even more effect in horizontal axis.
- the four quadrants Ql, Q2, Q3 and Q4 have a concentric power progression.
- the central zone of the lens corresponding to a zone centered on the optical center of the lens element does not comprise optical elements.

- the optical elements may be disposed on the entire surface of the lens element.
- At least one optical element of the plurality of at least three optical elements 14, has an optical function of not focusing an image on the retina of the eye of the wearer for peripheral vision.
- focusing is to be understood as producing a focusing spot with a circular section that can be reduced to a point in the focal plane.
- such optical function of the optical element reduces the deformation of the retina of the eye of the wearer in peripheral vision, allowing to slow down the progression of the abnormal refraction of the eye of the person wearing the lens element.
- optical elements may be as represented on figure 1, non-contiguous optical elements.

- At least one, preferably all of the, optical element of the plurality of optical elements 14, has an optical function of not focusing an image on the retina of the eye of the wearer, in particular for peripheral vision and preferably for central and peripheral vision.
