Definitions
- the present invention relates to a method of producing a polarizing ophthalmic lens which is adapted to the eye / head behavior of a wearer thereof. It also relates to the lens itself, which includes areas associated with polarization filters having different orientations. These zones are determined according to the wearer's eye / head behavior.
- Natural light is not polarized: the electromagnetic waves of which it is composed vibrate in all directions. David Brewster, from 1811, showed that for a certain incidence, a monochromatic light that is reflected on a transparent surface is polarized at 100%. Brewster's Law states that the polarization direction of the reflected wave is parallel to the plane of reflection. Thus the reverberation of a light on a horizontal plane is polarized horizontally.
- Polarizing ophthalmic lenses have been designed in response to these physical properties of reflected light. A lens whose direction of polarization is horizontal selectively filters the light rays that come from reflection on horizontal transparent surfaces. These glasses are particularly effective at eliminating troublesome reverberations on water bodies, on floor coverings, on sand or on snow. Nevertheless, horizontal reflective surfaces do not constitute the majority of potential sources of glare. Thus, light is reflected on the windows of a building or car is, unlike the previous case, polarized vertically.
- Some features of the landscape present in a person's field of vision are unique in urban areas.
- the urban environment has in particular many vertical reflective surfaces, such as, for example, glazing of buildings. These vertical walls generate reflections whose intensity may be sufficient to cause glare.
- Such glare is a source of discomfort, but it can also be a source of danger in some circumstances. This is particularly the case for a driver of a motor vehicle or motorcycle, for example.
- his eyes and his head move to guide his gaze on the area of interest.
- the spatial and temporal coordination of the movements of the eyes and the head has been the subject of numerous investigations.
- the document FR 2 863 857 in the name of the Applicant of the present patent application, describes a method for measuring the amplitudes of eye and head movements of the wearer of an ophthalmic lens. It appears that the strategy used to explore one's environment is unique to each individual. When a target is presented in the peripheral visual field, the relative participation of the head and the eyes varies from one subject to another: for some, who are called “head-movers", most of the movement will be carried out by the head ; for others, which are called “eye-movers”, the eyes will be mainly put into play to bring the eye to the target (Afanador et al., 1986, Fuller, 1992).
- the propensity to move the head or eyes the most is measured by a gain obtained by dividing the angular deviation of the head by the angular eccentricity of the target.
- a gain of 1 means that the observer did not move the eyes and that all the movement necessary to place the gaze on the target was made by the head; it is then a subject of the "head-mover” type.
- a gain of 0 on the contrary characterizes an observer "eye-mover". But individuals are not distinguished into two categories “head-movers” vs. "eye-movers”. There is indeed a continuum of behaviors between the two extreme behaviors described previously (Fuller, 1992).
- An object of the present invention is to provide a personalized protection of the visual function of an ophthalmic lens wearer, against glare that is caused by reverberations of light on reflecting surfaces, taking into account the eye / eye behavior. individual head of each lens wearer.
- the present invention provides a method for producing a polarizing ophthalmic lens which is divided into several zones associated with polarization filters having respective variable orientations.
- the method comprises the following steps, so that the lens is adapted to the eye / head behavior of a wearer thereof: / 1 / characterizing relative magnitudes of respective eye and head movements of the wearer; 121 depending on a result of step / 1 /, defining the areas of the lens that are associated with each polarization filter orientation; and / 3 / manufacturing the lens by incorporating therein, in each zone defined in step 121, a polarization filter which has the orientation corresponding to this zone.
- step / 1 / of the method may comprise a gain calculation for an "eye / head" movement coordination test performed for the wearer. This gain then constitutes the result that is considered in step 121, and is equal to the angular deflection of the wearer's head divided by an angular eccentricity of a target viewed by the wearer.
- the customization of a protection against glare caused by reverberations of light sources on transparent surfaces consists of adapting the dimensions of the different polarization zones according to the propensity of the observer to move more the eyes or the head when exploring its environment.
- the general principle of this customization is to provide a central area that is wider as the wearer tends to move the eyes. Conversely, this area will be reduced for a more "head-mover" wearer.
- the size of the central zone, and consequently of the peripheral zones, is thus not fixed in a single general way. It varies continuously and is determined by the gain that results from the evaluation tests of eye-head coordination.
- This customization has the advantage of optimizing the protection against dazzling.
- a dazzling source is present at 40 ° of eccentricity; - the polarization orientation of this source ensures that it can be filtered only by the peripheral areas of the design;
- the polarizing lens has a central zone covering an observation field of ⁇ 20 °; - AT -
- a target of interest appears at an eccentricity of 30 ° towards the source.
- ophthalmic lenses are understood all lenses of inorganic and organic material, of composition and in variable forms adapting in particular to a spectacle frame for protecting and / or correcting the view, these lenses being chosen from afocal, unifocal, bifocal, trifocal and progressive.
- polarizing ophthalmic lens By use position of the polarizing ophthalmic lens is meant the position of this lens when it is adapted in a frame, or in a holding element, in front of the eyes of a person in accordance with the normal use of the frame or of the element, for a vertical position of the person's head.
- vertical direction reference is made to the vertical gravitational direction.
- a horizontal direction is at an angle of 90 ° to the vertical direction.
- optical center of a lens is often confused with the geometric center of the lens before machining. More generally, the optical center can be defined in one of the following ways:
- orientation of a polarization filter is meant the orientation of the electric field of an incident light for which the intensity of the light transmitted by this filter is minimal or zero.
- linear polarizations of light or linear components of light polarization, are considered.
- Natural light is not polarized because it has no preferred direction of the electric field.
- a light that is reflected on a transparent surface is polarized.
- the polarization direction of the reflected wave is parallel to the plane of reflection. Thanks to the presence of a polarization filter oriented vertically in at least one area of the lens, the light that comes from reflections on vertical walls is attenuated for the wearer looking through this area. Improved visual comfort results, especially in urban areas.
- the polarizing lens may further comprise at least one non-polarized zone.
- Each zone of a lens made according to the invention therefore takes into account the behavioral parameters eye / head of the wearer.
- At least two of the areas are associated with light polarization filters.
- the light passing through the lens is affected differently for the two areas, depending on a polarization direction of this light.
- the polarization filter of at least one of the zones is oriented vertically with respect to the use position of the ophthalmic lens, and the polarization filter of at least one of the other zones is oriented horizontally with respect to the position of use of the lens.
- the zone that is associated with the vertically oriented polarization filter is located in a lateral portion of the lens, adjacent an edge of the lens relative to its use position.
- the lens is then particularly adapted to the current glare situation in an urban environment, according to which the reflection on a vertical wall is situated in a lateral part of the field of view.
- Such a situation corresponds in particular to the case of a walker or a motorist who looks in the direction of a street lined with windows causing reflections. It also corresponds to the case of a vehicle driver who suffers glare due to the reflection of light on vehicles to his right and / or left.
- a lens of a first type that can be used for the invention can comprise at least two zones and have the following characteristics: the polarization filter of one of the zones of the lens can be oriented vertically with respect to the position of use of the lens.
- This vertically oriented filter area is located adjacent a temporal lateral edge of the lens with respect to its use position; and the polarization filter of another zone of the lens can be oriented horizontally with respect to the position of use of the lens.
- This other horizontally oriented filter area is located adjacent to an upper edge of the lens, extends vertically towards a lower edge of the lens, and extends laterally from a nasal lateral edge of the lens. lens towards the temporal lateral edge, up to a distance L which is measured from an optical center of the lens to the lateral temporal edge.
- the distance L is then fixed at step 121 between 1 mm and 25 mm. It is equal to 1 mm when a gain equal to 1 is obtained for the wearer on the "eye / head" movement coordination test, and is equal to 25 mm when a gain equal to 0 is obtained for the test wearer. Movement coordination "eye / head”.
- the distance L can be defined in step 121 by applying a continuous linear relationship between the gain that is obtained for the wearer at the "eye / head" coordination test and this distance L.
- An example of a lens of the first type is shown in FIG. 2.
- the lens comprises only two zones: a first zone 2a which is associated with a polarization filter oriented vertically with respect to the use position of the lens, and a second zone 2b juxtaposed with the first zone 2a and which is adapted to affect the light passing through this second zone in a different way from the first zone depending on the direction of polarization of the light.
- the peripheral protection that is obtained by the zone 2a, the zone 2b being always considered as the protection in the central visual field may be considered only for visual temporal hemichamps. It corresponds to the lateral temporal edge (LT) of the lens, as opposed to the nasal lateral edge (LN) of the lens, which corresponds to an area where the nasal visual hemi-amps occur.
- LT lateral temporal edge
- LN nasal lateral edge
- the choice of temporal visual hemichamps may be justified insofar as the nasal visual hemi-amps are only slightly exposed to the peripheral genes, taking into account the protection afforded by the wearer's nose, and also by the nose of the mounted frame.
- the polarization filters of two zones of the lens can be oriented vertically with respect to the use position of the lens.
- a first of these vertically oriented filter areas is located adjacent to a temporal side edge of the lens relative to its use position, and a second of these areas having a vertically oriented filter is located from adjacent to a nasal lateral edge of the lens with respect to its use position;
- the polarization filter of another zone of the lens can be oriented horizontally with respect to the position of use of the lens.
- This other horizontally oriented filter area is located adjacent to an upper edge of the lens, extends vertically towards a lower edge of the lens, and extends laterally continuously over a distance d between the two. zones having vertically oriented polarization filters, the distance d being measured on a straight line passing through an optical center of the lens and being distributed equally on either side of a vertical line passing through the optical center.
- the distance d is set at step / 2 / between 2 mm and 50 mm. It is equal to 2 mm when a gain equal to 1 is obtained for the wearer on the "eye / head" movement coordination test, and is equal to 50 mm when a gain equal to 0 is obtained for the test wearer. Movement coordination "eye / head”.
- the distance d can be defined at step 121 by applying a continuous linear relationship between the gain obtained for the wearer at the "eye / head" coordination test and this distance d.
- FIG. 3 An example of a lens of the second type is illustrated in FIG. 3.
- two peripheral zones 2a are associated with vertically oriented polarization filters and a central zone 2b is associated with a polarization filter oriented horizontally with respect to the position. of use of the lens.
- This central area helps to mitigate dazzling sources from light reflection on horizontal surfaces, such as bodies of water and wet roads.
- Such a lens is particularly suitable for comfort during driving.
- the central zone which is associated with a horizontally oriented polarization filter extends over a width of 2 mm for an observer having a "head-mover" behavior, obtaining a gain of 1 in the measurement of the eye-eye coordination head, up to 50 mm for an observer "eyemover", that is to say, obtaining a gain of 0 to the test mentioned above.
- These dimensions are measured on a horizontal line passing through the optical center of the lens as defined above and on both sides, in equal quantity towards the temporal zone and the nasal area, of a vertical line passing through this same point. (In other words, the width d of the central zone 2b ( Figure 3) is divided half to the left of the optical center and half to the right of the optical center).
- a lens which is used for the invention may further comprise an additional area which is non-polarizing or which has an obliquely oriented polarization filter.
- This additional area extends laterally in the direction of the vertically oriented polarization filter area (s), is located in a lower portion of the lens for its use position, adjacent to the region having a horizontally oriented polarization filter. , and has an upper limit that passes between the optical center of the lens and a point 20 mm below this optical center for the use position of the lens.
- This extra area may have no polarization filter.
- it may have a polarization filter whose oblique orientation is between 0 ° excluded and 90 ° excluded from the vertical direction for the position of use of the lens.
- the oblique orientation of this filter may also be equal to 135 ° with respect to the vertical direction for the use position of the lens.
- the upper limit of this additional zone can also be fixed during step 121 of the method of the invention, so that it passes at 7 mm below the optical center of the lens when a gain equal to 0 is obtained for the wearer on the "eye / head" motion coordination test.
- the upper limit of the additional zone can be set at step 121 so that it goes to 3, 5 mm below the optical center of the lens.
- the polarizing lens can therefore also have four different areas, and even more. It may comprise in particular first and second zones, each of which is associated with a polarization filter oriented vertically with respect to the position of use of the lens, a third zone which is located between the first and second zones and which has a filter of horizontally oriented polarization, and at least a fourth zone, located for example under the third zone, for affecting the light passing through this fourth zone in a manner different from the first, second and third zones.
- the fourth zone may notably not be polarized or have an oblique polarization direction (FIG. 4).
- the invention also provides a polarizing ophthalmic lens made in the manner described above.
- Such a lens is divided into several zones which are associated with respective polarization filters, and is adapted to the eye / head behavior of the wearer of this lens.
- FIG. 1 illustrates the perception of a light source according to the behavior "eye / head" of a lens carrier
- FIG. 2 shows a polarizing ophthalmic lens comprising a zone (2a) associated with a polarization filter oriented vertically with respect to the use position of the lens, and a second zone (2b) associated with a polarization filter oriented horizontally with respect to the position of use
- - Figure 3 shows a polarizing ophthalmic lens having two zones (2a) associated with polarization filters oriented vertically with respect to the use position of the lens and located adjacent to the lateral edges of the lens. and a third zone (2b) associated with a polarization filter oriented horizontally with respect to the position of use;
- Figure 4 illustrates a pair of spectacles comprising two polarizing ophthalmic lenses made according to the invention
- FIG. 5 shows a polarizing ophthalmic lens comprising two peripheral zones (2a) associated with polarization filters oriented vertically with respect to the position of use of the lens and positioned adjacent to a third zone (FIG. 2b) associated with a horizontally oriented polarization filter located in the upper central portion of the lens, and a fourth non-polarizing zone (2c) located in the lower portion of the lens; and FIG. 6 (FIG.
- a polarizing ophthalmic lens comprising two peripheral zones (2a) associated with polarization oriented vertically with respect to the use position of the lens and positioned adjacent to a third zone (2b) associated with a horizontally oriented polarization filter and located in the upper central portion of the lens, and a fourth zone having an oblique polarization filter (2c) located in the lower part of the lens.
- a pair of spectacles comprises a frame 1 with two branches 3, equipped with two glasses 2.
- the word glass is taken in its usual sense as an ophthalmic lens cut out for a pair of spectacles, without relation to the nature of the lens. constituent material of it.
- a spectacle lens as considered in the context of the invention may therefore be made of mineral material, for example based on silicate, or of organic material, such as polycarbonate; polyamide; polyimides; polysulfones; copolymers of polyethylene terephthalate and polycarbonate; polyolefins, especially polynorbornenes; polymers and copolymers of diethylene glycol bis (allyl carbonate); (meth) acrylic polymers and copolymers, especially polymers and (meth) acrylic copolymers derived from bisphenol-A; thio (meth) acrylic polymers and copolymers; urethane and thiourethane polymers and copolymers; epoxy polymers and copolymers and episulfide polymers and copolymers.
- organic material such as polycarbonate; polyamide; polyimides; polysulfones; copolymers of polyethylene terephthalate and polycarbonate; polyolefins, especially polynorbornenes; polymers and copoly
- a spectacle lens may be only a polarization filter support.
- the two faces of the glass are parallel, so as not to introduce any image distortion.
- It can also be a glass with an ophthalmic correction function, whatever the nature of the correction (correction of myopia, astigmatism, hyperopia and presbyopia).
- It can be in particular a glass afocal, unifocal, bifocal, trifocal or progressive.
- the glass can still be associated with other optical functions, such as a sun protection glass or a photochromic glass ....
- the glass 2 is divided into three distinct areas.
- Zone 2a is associated with a horizontally oriented polarization filter.
- C denotes the optical center of the glass 2.
- the distance d represents the total width of the zone 2b equally distributed on either side of the center C.
- the distance d is between 2 and 50 millimeters, that is to say 1 and 25 mm respectively on each side of the center C. It is equal to 50 millimeters for an "eye-mover" observer, having obtained a gain of 0 in the eye-head coordination test.
- a gain of 0.5 which represents a propensity of the wearer to rotate the head and the eyes equally when exploring his peripheral visual environment, then corresponds to a width d of the zone 2b of 26 mm (13 mm on each side of the optical center C).
- Such a lens is particularly suitable, for example, for a vehicle driver in an urban environment.
- Zone 2b is associated with a polarization filter oriented horizontally with respect to the position of use of the pair of glasses.
- Zone 2c is not associated with any polarization filter (FIG. 5) or with an obliquely oriented polarization filter (FIG. 6).
- the zone 2c therefore makes it possible not to attenuate the polarized light sources (FIG. 5), or to facilitate the perception of sources having an obliquely oriented polarization in a manner opposite to the orientation of the filter of this zone (FIG. 6).
- the carrier driver of a pair of spectacles equipped with lenses according to FIG. 5 or 6 is thus protected against both dazzling caused by reflections on vertical walls located laterally in his field of vision, and against reflections from the surface of a road in front of him.
- the lower central part of its field of view, corresponding to the zones 2c is affected either by a non-polarizing filter making it possible not to limit the visibility of the liquid crystal displays that emit polarized light, or by a polarized filter. 135 degrees to ensure that the on-board displays that emit polarized light at 0 or 90 degrees are not extinguished. This allows the driver to read them, and also ensures increased visual perception of active matrix edge displays that produce 45-degree polarized light.
- the inventors have determined that a good compromise is obtained when the zone 2c has an upper limit passing between the optical center and a point located at 20 millimeters. below this center.
- the participation of the head in a downward or upward gaze movement is less important than when moving horizontally. Nevertheless, there is also some difference between individuals.
- the participation of the head in the vertical direction is half as important as in the horizontal direction. We can therefore consider that the maximum gain in the vertical direction is 0.5.
- the essential driving elements that can be impacted by the polarization orientation properties of the spectacle lens are the liquid crystal displays such as speed meters, navigation visuals, etc. These elements, given the requirements of ease and speed of access to the information they give, are rarely located below 20 ° down.
- an individual "eye-mover” will tolerate a lower positioning of the zone 2c than an individual "head-mover".
- the boundary placed 7 mm below the optical center is the limit to see a visual located at 20 ° downward through zone 2c.
- the border will have to be placed at the highest point at 3.5 mm under the optical center.
- each polarization filter can be made according to one of the technologies known to those skilled in the art, not described here. It can be a filter by absorption of polarized light in a particular direction or, possibly, a filter by reflection of light polarized in this direction.
