Definitions
- the present invention relates to a progressive ophthalmic lens for myopia correction and a method for producing such a lens.
- the foveal vision corresponds to the observation of the object with the central part of each retina, which is called the foveal zone.
- the lateral parts of the observed object which are imaged by light rays penetrating obliquely in the eye, correspond to the peripheral vision of the wearer. The skilled person then speaks of over-correction of myopia in these conditions of peripheral vision.
- the document WO 2007/041796 indicates that the size of the central zone, which is adapted for the foveal vision, can be personalized for each wearer of glasses, according to his behavior to move rather the eyes and / or the head .
- some children accomodate imprecisely when they observe an object which is situated at a short distance from them, that is to say in conditions of near vision. Because of this lack of accommodation on the part of a myopic child who is corrected for his vision from afar, the image of a close object is also formed behind his retina, even in the foveal area.
- a corrective glass of myopia which is of the progressive glass type.
- Such a lens comprises a far vision zone, in which the optical power of the lens is adapted to correct the myopia of the wearer when he observes a distant object, a near vision zone, in which the correction of myopia is reduced, and an intermediate zone which is located between the far and near vision areas, and in which the optical power of the lens varies continuously.
- Such progressive ophthalmic lenses are adapted for the foveal vision of the wearer. Nevertheless, it has been found that each of these two types of ophthalmic lenses, with a zone adapted for peripheral vision, on the one hand, or progressive, on the other hand, still causes a residual worsening of the ametropia of the wearer.
- An object of the present invention is then to provide a new type of ophthalmic lens, which is suitable for a myopic carrier and which further reduces the risk of increasing the degree of myopia in the long term.
- the invention proposes a progressive ophthalmic lens which is adapted to correct a myopia of a wearer of this lens, and which comprises:
- the lens has a first optical power value which is adapted to perform the myopia correction for the foveal vision of the wearer, in far vision condition;
- a near vision zone which is located below the far vision zone for a position of standard use of the lens by the wearer, and in which the lens has a second optical power value which is adapted for the foveal vision of the wearer in near vision condition, this second value corresponding to a first reduction of the myopia correction with respect to the first value;
- the lens having a third optical power value in a reference point which is located in this intermediate zone and which corresponds to a straight direction in front of the wearer's eye for the standard use position of the lens.
- the reference point in the intermediate zone of the glass, at which the third optical power value is achieved may be the glass mounting center which is considered to assemble the glass in a frame.
- the glass is characterized in that it further has, in an upper area thereof which is located above the far vision zone and laterally on each side of the reference point for the use position.
- standard of the glass fourth optical power values which are adapted for the peripheral vision of the wearer when the direction of gaze of the wearer is straight ahead through the glass, and which correspond to a second reduction of the myopia correction with respect to the third optical power value.
- the invention combines, within a single ophthalmic myopia correction lens, the characteristics of a progressive lens with those of a lens which is adapted to correct differently the foveal and peripheral visions of the wearer.
- the myopia correction that is obtained is adapted to variable observation conditions, both when the observation distance varies - far vision, intermediate vision and near vision - and when the eccentricity of the observation varies. parts of an object that is observed - foveal vision and peripheral vision.
- the worsening of the myopia of the wearer that provokes all these different observation conditions is avoided or reduced.
- the glass is divided into at least four zones: far and near vision zones, as well as the intermediate zone, in which the myopia correction is more specifically adapted to the foveal vision, and the upper zone in which the myopia correction is more specifically adapted to the peripheral vision for the direction of gaze straight ahead.
- the glass in the context of the invention, by standard use position of the glass is meant the position of the latter when it is assembled in a spectacle frame, and this is placed on the wearer's face with his head held. vertically, or slightly bent forward.
- the variations in the optical power of the lens between the far vision zone and the upper zone, which is dedicated to the correction of the peripheral vision, are continuous, as are those appearing on each side of the reference point, between that zone. ci and the upper zone.
- these variations in optical power may result from continuous variations in a curvature and / or a refractive index of the glass present in the same areas of the glass.
- the image of the observed object is formed in a continuous surface, which coincides with the retina both in the foveal area and in the peripheral zone of the retina, or which does not substantially deviate from the retina in the peripheral zone.
- the fourth optical power values in the upper zone of the lens can in particular correspond to absolute differences which are greater than 0.5 diopter with respect to the third optical power value, the latter being suitable for foveal vision and for the direction right in front of the wearer's gaze.
- one of the fourth values of the optical power, for peripheral vision and for the right direction in front of the wearer's gaze, which corresponds to an eccentricity of 30 ° inside the upper zone of the lens may present a deviation absolute which is substantially equal to 0.8 diopter with respect to the third optical power value.
- a distribution of the fourth optical power values of the lens, for peripheral vision and for the right direction in front of the wearer's glance, is substantially constant during a rotation around the reference point. , at inside the upper area of the glass. Peripheral vision for the right gaze direction in front is then corrected uniformly in a wide angular sector.
- the fourth values of the optical power, for the peripheral vision and for the straight direction in front of the wearer may have absolute differences, with respect to the third optical power value. , which grow in relation to a distance from the reference point, within the upper zone of the glass.
- the correction of myopia is regularly decreased in the upper zone of the lens for the peripheral vision of the wearer, starting from the correction value at the reference point of the lens.
- the invention also proposes a method of producing a progressive ophthalmic lens which is adapted to correct a myopia of a carrier of this lens.
- This method comprises the following steps: determining a first optical power value of the lens which is adapted to correct the myopia for a foveal vision of the wearer, in far vision condition;
- determining a second optical power value of the lens which is adapted for the foveal vision of the wearer in close vision condition, and which corresponds to a first reduction of the myopia correction with respect to the first value
- the method is characterized in that it further comprises the following steps: - determining a third optical power value of the glass for the gaze direction of the right holder in front through the glass; and
- determining at least a fourth optical power value of the lens which is adapted for the peripheral vision of the wearer when the direction of gaze is straight ahead through the lens, and which corresponds to a second reduction of the myopia correction with respect to the third optical power value.
- the glass is then produced by further conferring the third optical power value at the point of the intermediate zone of the glass which corresponds to the direction of straight ahead of the carrier, said reference point, and the fourth optical power value in at least a point of an upper zone of the glass which is situated above the far vision zone and, laterally, on each side of the reference point for the standard use position of the glass.
- the optical power of the lens varies continuously between the far vision zone and the upper zone, as well as between the reference point and the upper zone.
- a progressive ophthalmic lens as described above can be achieved using this method.
- a method according to the invention thus comprises, in addition to the realization of the near and far vision zones of the progressive lens according to a prescription which is established for the wearer, the determination of the myopia correction which is adapted for the vision. the wearer's device when he looks straight ahead through the glass.
- the realization of the glass thus combines obtaining an addition between the near and far vision zones, with the adaptation of a zone of the glass more particularly for peripheral vision. This zone, which is more particularly adapted for peripheral vision and which is called the upper zone, is distinct from the near, intermediate and intermediate viewing zones of the glass.
- some of the fourth values of the optical power in the upper zone of the lens, for the peripheral vision and for the right direction in front of the wearer's gaze can correspond to an under-correction of the myopia of the wearer for these conditions of observation.
- some of the fourth optical power values in the upper zone of the lens can be determined so that the myopia of the wearer is only partially corrected for the peripheral vision and the direction of the gaze ahead.
- the method may further comprise the following step, which is performed before the production of the glass:
- One of the fourth optical power values for peripheral vision and for the right direction in front of the wearer's glance, is then adjusted for a non-zero fixed eccentricity, for example 30 °. It is adjusted so as to have an absolute distance with the third optical power value, which increases as a function of the relative amplitude of the wearer's head movements, in the sense of a reduction of the myopia correction.
- FIGS. 1a and 1b are optical power characterizations of a first ophthalmic lens made according to the invention, respectively for the foveal and peripheral visions of the wearer;
- FIGS. 2a and 2b respectively correspond to FIGS. 1a and 1b, for a second ophthalmic lens taken for comparison;
- FIGS. 3a and 3b illustrate a principle of measurement of eye and head movements for a spectacle wearer.
- Figures 1a, 1b, 2a and 2b are optical power maps of two ophthalmic lenses progressive myopic.
- the abscissa and ordinate axes are identified by the values angular displacement of a light beam that enters the eye, with respect to the optical axis of the glass respectively in a horizontal plane and in a vertical plane. They are marked in degrees and denoted ALPHA and BETA, ALPHA denoting the offset in the vertical plane, and BETA the offset in the horizontal plane.
- the null values of ALPHA and BETA correspond to the gaze direction of the upright wearer in front of him, which is denoted O.
- a displacement in a mapping that is established for foveal vision corresponds to a rotation of the eye behind the lens, while a displacement in a map that is established for peripheral vision ( Figures 1b). and 2b) corresponds to a displacement in the image that is formed on the retina when the eye is immobile in the direction of gaze O.
- Positive values of ALPHA indicate a direction of gaze which is inclined downwards for the eartographs foveal vision, and indicate a light ray that comes from the lower part of the visual field for peripheral vision eartographies.
- the curves shown connect points for which the optical power is constant. Since they are myopia correcting lenses, the optical power values are negative. A reduction of the correction therefore corresponds to a positive variation of the optical power, that is to say to values of the optical power of the glass which are close to zero, or which may become positive, possibly.
- the glasses according to the invention are progressive: for the foveal vision, the optical power varies continuously between a distant point of vision of the glass and a point of near vision.
- the indications VL and VP correspond to the rectilinear directions which pass through the center of rotation of the eye and, respectively, by the points of vision from far and near the glass.
- the indications VL and VP correspond to rectilinear directions which pass through the center of the pupil of the eye and, respectively, by the points of vision from far and near the glass.
- the eartographs of Figures 1a and 1b have been established for a first spectacle lens according to the invention.
- This first lens corresponds to a correction of -6.0 dioptres at the far vision point and at an addition + 2.0 dioptres surface area of the progressive face.
- This surface addition value corresponds to an optical addition of 2.25 diopters in the carrier mode, the latter value being the optical power difference that appears in FIG. 1a between the viewing direction VP and the direction VL.
- the far vision zone corresponds to the points of the glass for which the optical power for the foveal vision is close to the value for the far vision point, for example with a deviation from this value at the point distance vision which is less than 0.5 diopter in absolute value.
- the mapping of FIG. 1b shows that the optical power deviation for the peripheral vision with respect to the value in O is greater than
- this gap increases radially in the direction of a reduction of myopia correction.
- the distribution of the optical power for peripheral vision has approximately a symmetry of revolution about the direction O.
- the upper zone S which is illustrated in FIG. 1b is bounded by two arcs. in circles, but it is understood that such a shape of the area adapted for peripheral vision is given for illustrative purposes, in a simplified way.
- the exact shape of the zone S can indeed be adapted in a variable manner, as will be seen in the following considering the amplitudes of the movements of head and eyes made by the wearer.
- the value of the optical power at at least one point of the zone S can be determined from a measurement which is carried out on the carrier of the first lens.
- a measure may be a self-defeating or skiascopy measure.
- At least one of the values of the optical power in the area S can be determined for a reference eccentricity, by reducing by a fixed amount the myopia correction which is performed at the reference point of the glass, for peripheral vision.
- the optical power for a light beam direction which makes a BETA angle of +/- 30 ° with the direction O is modified by about 0.8 diopter with respect to the optical power value. for the direction O.
- the first glass can be made by varying at least one curvature of a face thereof parallel to this face, in a manner that is known per se.
- One of the processes for machining ophthalmic lenses that are also known to a person skilled in the art can then be used to impart to the face of the glass the determined variations in curvature.
- a refractive index of a glass material can be varied, even parallel to the face of the glass, to give it the local optical power characteristics that correspond cartographies.
- the maps of FIGS. 2a and 2b have been established for a second spectacle lens, for comparison.
- This second lens also corresponds to a correction of -6.0 diopters at the far vision point and a surface addition of + 2.0 diopters of the progressive face. Comparing the maps of Figures 1b and 2b, it appears that myopia correction for peripheral vision decreases more rapidly away from the central point of the image that is formed on the retina, laterally on each side of the point O and above point VL, for the first glass as for the second glass. Since the prescribed myopia correction is determined for the foveal vision and corresponds to an over-correction for the peripheral vision, the first lens (FIGS. 1a and 1b) provides a better correction of the peripheral vision compared to the second lens ( Figures 2a and 2b).
- the far vision zone of the lens which is located around the far vision point and in which the ophthalmic correction is adapted for the foveal vision, is less extensive for the first lens (FIG. the second glass ( Figure 2a).
- Glasses having optical power distributions that are intermediate between those of the first and second glasses described above can be made likewise. There is thus a compromise, for myopia corrections that are identical to the far and near vision points of the lenses, between an adaptation of the corrections more for the foveal vision or more for the peripheral vision. According to an improvement of the invention, this compromise can be adapted to the wearer of the glass, depending on his propensity to use rather his foveal vision or rather his peripheral vision. Such a customization of a glass according to the invention then brings in addition to the wearer a visual comfort which is superior.
- This improvement of the invention consists in taking into account a behavioral characteristic of the wearer to favor the correction of the foveal vision or that of the peripheral vision.
- This behavioral characteristic is the propensity of the wearer to turn more head or eyes when observing an object that is not located in front of him.
- a larger area of the lens that corrects the foveal vision of the wearer is preferred.
- the image of an object that is observed by the wearer is then correctly formed on the retina, for a higher range of angle of rotation of the eyes.
- a wearer who moves his head mostly looks through the glass in a restricted area which is located around his center, the latter being associated with the direction of gaze O. It is then preferable that the upper zone of the glass, in which the peripheral vision is more precisely corrected, or more extensive. This increase in the upper zone appears in particular on each side of the center of the glass, in the direction of the latter in a roughly horizontal direction.
- an optimal compromise between the myopia correction for peripheral vision and that for foveal vision, on the entire surface of the ophthalmic lens can be obtained.
- This compromise varies depending on the carrier. It can be adapted to provide a good foveal vision comfort for a wearer who mainly moves the eyes, while still providing a correction adjusted to its peripheral vision for very inclined light rays.
- the relative magnitudes of eye and head movements for the future carrier for which the glass is intended are firstly characterized.
- the reference target is denoted R in Figure 3a. It is located preferably at eye level for the wearer. The wearer is therefore placed in front of the reference target, with the shoulders substantially located in a vertical plane that is perpendicular to the virtual line that connects his head to the reference target. He then has the head and the eyes that are oriented toward the reference target.
- the bearer is then asked to look at a second target, referred to as the test target and noted T, which is offset from the reference target, without moving the shoulders.
- the test target and noted T which is offset from the reference target, without moving the shoulders.
- the test target is horizontally offset from the reference target, so as to characterize the horizontal movements of the wearer's head and eyes.
- the angular offset of the test target relative to that of reference is called eccentricity, and denoted E.
- E The angular offset of the test target relative to that of reference.
- ⁇ r denotes the angle of rotation of the wearer's head, also called angular deflection of the head, to move from the first observation situation of the reference target to the second observation situation of the the test target
- ⁇ y is the angle of rotation of the eyes that is performed simultaneously by the wearer.
- the eccentricity E is therefore equal to the sum of the two angles ⁇ ⁇ and ⁇ ⁇ .
- the quotient of the angular deviation of the head ⁇ j is then calculated by the eccentricity E. This quotient is equal to unity for a wearer who has exclusively turned the head to move from the reference target R to the test target T , and zero for a wearer who has only turned his eyes.
- a G gain is then calculated for this "eye / head" motion coordination test that has been performed for the wearer.
- the gain G can be defined by a predetermined increasing function of the quotient of the angular deviation of the head ⁇ ⁇ by the eccentricity E.
- G ⁇ -r / E.
- a wearer who essentially turns his eyes to fix the test target therefore has a gain value G close to zero, and a wearer who essentially turns his head to fix the same target has a value of G close to unity .
- This "eye / head" movement coordination test can be performed by the wearer in the shop of an optician retailer where he orders his pair of glasses equipped with corrective glass.
- the optical power value of the glass for the peripheral vision, at a point of the upper zone S of the glass which corresponds to an eccentricity of 30 °, is then adjusted as a function of the value obtained for the gain G.
- This adjustment can consist of vary the difference in optical power with respect to the point of the glass that corresponds to the direction O, or with respect to a value that is deduced from a measurement made on the carrier.
- the absolute difference in optical power between the point of the upper zone S which corresponds to the eccentricity of 30 ° and the point of the glass which corresponds to the direction O is preferably decreased for an amplitude of the eye movements of the wearer. is important, that is to say a value of the coefficient G close to 0.
- one of the fourth optical power values which is performed for a non-zero fixed eccentricity, for example 30 °, corresponds to a reduction of the myopia correction with respect to the third optical power value. which is performed at the reference point, this reduction being an increasing function of the value of the coefficient G.
- the limit of the upper zone S towards the reference point, at least on each side of this point, is then displaced according to the relative amplitude of the head movements of the wearer.
- the length of this displacement increases as a function of the relative amplitude of the movements of the wearer's head.
- the upper zone of the lens which is adapted to correct the myopia of the wearer in a more suitable way for peripheral vision, is increasing towards the point of reference for a wearer who turns his head more than the eyes.
- the size of the far vision zone of the glass may vary simultaneously, laterally to each side of the glass and possibly to the top of the glass for the standard use position thereof. It then decreases when the relative amplitude of the wearer's head movements increases.
