Description

EYEWEAR The invention relates to a pair of glasses comprising at least one spectacle lens with a left and a right spectacle lens section, a frame device which comprises a left and a right frame part, the frame device being in mechanical engagement with the there is at least one spectacle lens and the left frame part is assigned to the left spectacle lens section and the right frame part is assigned to the right spectacle lens section, wherein each frame part has a fastening section with a fastening recess into which fastening recess engages at least one fitting part arranged on a lateral end of the respective spectacle lens section ,

Numerous designs of glasses are already known from the prior art, in which individual frame parts and - depending on the design - optionally a continuous, one-piece glasses or two separate glasses can be mechanically plugged together. This has the advantage that in the event of damage to the lens and / or frame part, the individual parts of the glasses can be replaced simply and inexpensively. This is particularly advantageous in the case of sports glasses which are exposed to the high mechanical loads to which they are exposed when the user is exercising. In addition, parts of glasses that can be connected to one another by means of plug-in connections that can be connected to each other by glasses without special tools can also be adapted particularly flexibly to current designs and / or colors.

For example, from EP 2 159 623 B1 sports glasses with a continuous lens have become known in which a pair of elastically deformable left and right frame parts together with the brackets arranged thereon can be fastened to the lens by means of a plug connection. The nose pads or nose pads are fastened directly in a nose recess of the spectacle lens on the underside of the spectacle lens.

A low weight and the associated feeling of a comfortable fit are generally considered to be an important criterion for glasses, in particular sports glasses. Under no circumstances should glasses be annoying when worn for a long time.

A disadvantage of the design of sports glasses known from EP 2 159 623 B1 and of the sports glasses currently known is at least that when the glasses are subjected to an external force, for example in the event of an impact or during shaking and / or jerky movements during a sporting activity of the spectacle wearer, the entire weight of the glasses acts undamped on the nose pads and thus on the nose of the wearer of the glasses. When glasses are worn for a longer period during physical activity or during sports activities, this usually leads to signs of fatigue and pressure points in the area of the nose pads, which are uncomfortable for the user of the glasses.

It is the object of the present invention to provide improved glasses which avoids the disadvantages of glasses, in particular sports glasses, which are known from the prior art, and which are more comfortable to wear as well as longer, pain-free wearing of the glasses even during physical exertion Operation of the user or wearer of the glasses guaranteed.

This object is achieved in generic glasses by the features specified in the characterizing part of claim 1. Particularly advantageous, preferred embodiments and developments of the invention are the subject of the dependent claims. Spectacles according to the invention include:

[0011] at least one spectacle lens with a left and a right spectacle lens section,

AT 16 557 U2 2019-12-15 Austrian patent office - a frame device which comprises a left and a right frame part, the frame device being in mechanical engagement with the at least one spectacle lens and the left frame part the left spectacle lens section and the right frame part is assigned to the right spectacle lens section, [0013] each frame part having a fastening section with a fastening recess into which fastening recess at least one fitting part arranged at a lateral end of the respective spectacle lens section engages, each frame part each having an elastically resilient damping element, wherein each damping element is fastened to a fastening section and extends in the nasal direction of the spectacles along a lower edge of the respective spectacle lens section and from the lower edge to form a variable gap distance to a nas The end of the frame extends, wherein each damping element can be deflected flexibly and flexibly in at least one direction and wherein a nose pad is arranged on each of the nasal frame ends, which nose pad is set up in a wearing position of the glasses on the nose to lie against a user and support the respective frame part.

[0017] In general, the assignment of the terms with regard to a location or an orientation, such as “horizontal”, “vertical”, “in the horizontal direction”, “in the vertical direction”, “above”, “below”, “in front” "," Underneath "," above "etc. are only chosen for simplification and these terms may refer to the representation in the drawings, but not necessarily to the current position of use or wearing position of the glasses.

The anatomical position and directional designations used in the present application merely serve to simplify the description of the wearing position of the glasses according to the invention in their intended position on the front of the head of a user or spectacle wearer. The concept of a "nasal" direction generally stands for "towards the nose", ie pointing medially to the nose in the middle of the head. The term temporal direction generally means towards the temple, ie laterally or laterally on the head. An “upper” or superior direction generally means upward and a “lower” or inferior direction generally means downward.

Depending on the design of the glasses according to the invention, these have at least one spectacle lens with a left and a right spectacle lens section. The term “spectacle lens” also includes one or more spectacle lenses, which, for example, are or are made from an unbreakable, transparent plastic. In an alternative embodiment, the glasses can have two separate glasses instead of a continuous lens or a continuous lens. The term selected below for a left and a right spectacle lens section therefore relates equally to sections of a one-piece spectacle lens or a one-piece spectacle lens as well as to a left or a separate right spectacle lens in the case of a pair of glasses with two separate glasses. This is well known to the person skilled in the field of glasses.

Usually, the individual left or right components, such as frame parts or eyeglass temples, are in each case designed in pairs in mirror symmetry. However, in the case of optical glasses, the left and right spectacle lens sections or, in an embodiment with two separate spectacle glasses, the left and right spectacle glasses can have, for example, different optical lenses with the same or different number of diopters, in order to compensate for individual visual impairments of the user can. This is also well known to the person skilled in the art.

The glasses according to the invention furthermore have a frame device which comprises a left and a right frame part, the frame device in mechanical

Engagement with the at least one spectacle lens and the left frame part is assigned to the left spectacle lens section and the right frame part to the right spectacle lens section. Depending on the version, the left and right frame parts can each be made in one piece or in several parts. For example, a left and a right temple piece can be fixed rigidly, resiliently flexibly or articulated by means of appropriate temple hinges to the corresponding frame part. Likewise, temple pieces can be attached as separate components to the respective frame parts of the glasses. For example, the eyeglass temple can be attached to the associated frame part by means of a known articulation in the form of a hinge with the aid of a screw, a pin or a hinge pin. Likewise, in the case of glasses according to the invention, a frame device can be provided in which the left and right frame parts are connected to one another. For example, at least one nose bridge and / or a connecting bridge along the upper edge of the at least one spectacle lens can be used to connect the left and right frame parts. All of these different embodiments are encompassed by the present invention.

According to the invention, each frame part has a fastening section with a fastening recess into which fastening recess engages at least one fitting part arranged at a lateral end of the respective spectacle lens section. The at least one spectacle lens can advantageously be mechanically connected to each frame part and also separated again. Depending on the design variant, detachable positive and / or non-positive connections can be used to releasably connect one or more fitting parts at the lateral end of the respective spectacle lens sections or the respective separate two spectacle lenses to the corresponding frame part. By way of example, such releasable fastenings of the at least one spectacle lens to the respective frame part can be designed as a tongue and groove connection, a feather key connection, a dovetail connection, a plug connection, a screw connection or a clamp connection.

In a pair of glasses according to the invention, each frame part has an elastically resilient damping element, each damping element being fastened to a fastening section of the respective frame part and extending in the nasal direction of the glasses along a lower edge of the respective spectacle lens section and from this lower edge below Forming a variable gap distance extends up to a nasal frame end, each damping element being elastically flexibly deflectable at least in one direction and wherein a nose pad is arranged on each of the nasal frame ends, which nose pad is set up in a wearing position of the glasses on the nose to lie against a user and support the respective frame part.

As a major advantage of the glasses according to the invention, the damping elements offer particularly effective and comfortable cushioning of the glasses in the event of vibrations, as usually occurs in particular in sports such as mountain biking, running or skiing. Another advantage is that the freely vibratable damping elements, which serve as connecting elements between the fastening section of each frame part, which is connected to the spectacle lens, and the nose pads, a particularly flexible, individually adjustable fixation and alignment of the nose pads and thus the entire glasses allow in wearing position on the nose of the respective user. Unpleasant pressure points on the nose pads, which have so far inevitably occurred when wearing glasses, in particular sports glasses, during sporting activities, can be prevented particularly effectively in this way.

Each damping element is spaced from the lower edge or from the lower contour line of the at least one spectacle lens to form a variable gap distance. The nasal frame ends and the nose pads are also spaced from the at least one spectacle lens and are not directly connected to the spectacle lens or the spectacle lens. The respective damping element and the spectacle lens can thus advantageously swing independently of one another and relative to one another, in order to efficiently reduce the forces occurring in the event of an impact or in the case of jerky movements while wearing the spectacles

3/16

AT 16 557 U2 2019-12-15 Austrian patent office and steam. The nose pads are expediently made from a particularly skin-friendly, non-slip material and are designed in such a way that they can be adapted, for example, to the individual anatomy of a user's nose by means of appropriate molded inserts.

The damping elements significantly increase the wearing comfort of the glasses, especially in the case of jerky movements or shaking movements, the at least one spectacle lens of the glasses can swing at least in the vertical direction - starting from the wearing position of the glasses -, whereby the pressure is cushioned or taken from the nose pads ,

Depending on the design, the damping elements can be integrally connected to the fastening section of the respective frame part, which adjoins at one end and to which the damping elements are fastened, in glasses according to the invention. As an alternative to this, the damping elements can also be built in as connecting elements between the fastening section of each frame part and the nasal frame end or the nose pads as separate discrete components and, for example, be made of a different material than the adjacent parts of each frame part. For example, it can further be provided within the scope of the invention that the damping elements are produced as discrete components from a particularly flexible material with a higher dynamic strength or alternating bending strength than the parts of each frame part adjoining them.

The freely vibratable damping elements are thus advantageously only attached at one end to the respective fastening section of the respective frame part. At their other end in the longitudinal direction of the damping elements, which in the wearing position on the head of a user of the glasses points to the nose of the glasses wearer, the freely oscillating nose pads are provided on the nasal frame ends. Due to the release of the damping elements and the attached nose pads from the at least one spectacle lens, the damping elements together with the nose pads can freely swing relative to the eyeglass lens, thereby particularly effectively absorbing and dampening shocks and jerky movements of glasses during wear.

In the case of a pair of glasses according to the invention, the spectacle lens can be manufactured in one piece, the left and right section of the spectacle lens being connected to one another. This embodiment variant has the advantage, in particular for sports glasses, that the glasses have a particularly robust construction due to the one-piece spectacle lens. Another advantage of such a design with a one-piece spectacle lens is that the field of vision of the user is not impaired due to the continuous lens. Any connecting elements, such as are usually required for connecting two separate spectacle lenses, for example as a nose bridge, can advantageously be omitted in the case of spectacles with a one-piece spectacle lens. Such glasses can therefore be made particularly light, in particular when using a plastic lens, which in turn further increases the wearing comfort of the glasses due to the low weight.

In an alternative embodiment of glasses according to the invention, two separate glasses can be provided, the left and right glasses section in this variant being designed as separate glasses, which are preferably connected to one another with at least one intermediate nose piece.

This variant with two separate, separate glasses that can be connected to one another with one or more nasal bridges per se offers the advantage of also more elegant, less sporty glasses with the particularly comfortable nose pads that can be freely oscillated by means of the damping elements combine. If necessary, the two separate spectacle lenses can also have an eyeglass frame at least in sections. There are therefore no limits to the design options for combining different glasses designs with the elastically resilient damping elements according to the invention on the underside of the glasses lenses.

[0032] In a further expedient embodiment, glasses according to the inven4 / 16

AT 16 557 U2 2019-12-15 Austrian patent office the left and right frame parts can be designed as separate frame parts, preferably as mirror-symmetrically designed separate frame parts. In this embodiment variant, the two frame parts are fastened separately from one another at the mutually opposite lateral ends of the respective spectacle lens section. The two frame parts are connected to one another only by means of the at least one spectacle lens in between. Connection or nose bridges in the area of the upper edge of the lens are not required. In this embodiment, the weight of the glasses can advantageously be reduced further. Removing and exchanging the separate left and right frame parts from at least one spectacle lens is also particularly easy in this variant.

It can be particularly advantageous if, in the case of glasses according to the invention, the frame parts are attached exclusively to the lateral ends of the respective spectacle lens sections or spectacle lenses. In this embodiment, the fastening sections on the frame parts for fastening the spectacle lens sections can be of particularly small dimensions. In extreme cases, the fastening sections on the frame parts can be designed as punctiform. Such a particularly compact fastening of the spectacle lens or the spectacle lenses to the frame parts enables a further reduction in the weight of the glasses as a result of material savings for the frame parts.

In a further advantageous embodiment of the glasses according to the invention, it can be provided that the damping elements in a wearing position in the rest position of the glasses do not touch the respective lens sections or lenses. In this embodiment, the damping elements are spaced so far from the lower edges or the lower contour lines of the at least one spectacle lens that they do not touch the at least one spectacle lens in a wearing position of the glasses on the head of the wearer. The nasal frame ends adjoining the damping elements, together with the nose pads arranged thereon, are also appropriately spaced from the lower edges or the lower contour lines of the at least one spectacle lens. Depending on the geometry of the design and the selected distances between the respective damping element and the lower edge of the lens, this condition can not only be in an unloaded wearing position in the rest position, i.e. when the glasses are worn quietly and without vibrations, but also in a loaded wearing position during external force such as one Impulse due to a shock of the glasses.

In a further development of the invention it can be provided that the frame parts are connected to each other at their nasal frame ends with a middle piece, preferably with an elastic middle piece. This embodiment offers the advantage that the two nasal frame ends with the nose pads arranged thereon do not form free ends, but are connected to one another in a manner that is as flexibly movable as possible by means of a central piece. In particular with sports glasses, this design offers the advantage of a reduced risk of injury, since the connecting middle piece protects the free ends of the two nasal frame ends in a comparable manner to a protective bar. In the event of particularly strong vibrations of the glasses, such a centerpiece also secures the position of the nose pads on the user's nose and reduces the risk of the nose pads slipping unintentionally. A further advantage of this variant is that, for example, an optical clip, that is to say an additional pane with an optical vision correction, can be attached to the connecting center piece. Likewise, for example, a tinted, darkened additional lens can be attached to the center piece.

In a particularly robust embodiment of the glasses according to the invention, the frame parts and / or the elastically resilient damping elements can be made of a material which has a tensile modulus of elasticity of 1200 to 7000 MPa, preferably of 1400 to 3500 MPa, in particular of 1600 MPa.

The tensile modulus of elasticity expresses the relationship between the tensile stress and the tensile elongation of a material, in particular a plastic material. The modulus of elasticity or modulus of elasticity thus provides information about the rigidity of a material and is all the greater, depending

5/16

AT 16 557 U2 2019-12-15 Austrian patent office the smaller the deformation that a tested specimen experiences under a certain load.

In a pair of glasses according to the invention, the frame parts and / or the elastically resilient damping elements (211, 221) can expediently be made of a particularly dimensionally stable material which has a yield stress of 30 to 130 MPa, preferably 40 to 100 MPa, in particular 60 MPa. The tensile stress in plastics is used to determine the tensile properties and specifies the first stress value at which the elongation increases without increasing the stress. In the case of plastics, however, permanent deformation can take place even at stresses below the yield stress. A high yield stress indicates a strong, strong material.

In a pair of glasses according to the invention, the frame parts and / or the elastically resilient damping elements can advantageously be made of a dimensionally stable material which has an elongation at stretch of 2 to 8%, preferably 3 to 7%, in particular 6%.

In a further, particularly resistant embodiment of the glasses according to the invention, the frame parts and / or the elastically resilient damping elements can be made of an unbreakable material which has a breaking stress of 30 to 120 MPa, preferably 45 to 60 MPa.

A pair of glasses according to the invention can be made particularly robust if the frame parts and / or the elastically resilient damping elements are made of an unbreakable material which has an elongation at break greater than 2%, preferably greater than 10%, in particular greater than 50% ,

The following plastics, which can fulfill one or more of the aforementioned material properties, may be mentioned by way of example: high-performance plastics such as polyetherimides or polyamides and ABS plastics.

Representatives of the polyetherimides (abbreviated: PEI), which are among the polyimides, are plastics which are commercially available under the Ultem® brand name, for example in the Ultem® 1000 or Ultem® 2300 variants.

Acrylonitrile-butadiene-styrene copolymer plastics (abbreviated: ABS) are comparatively inexpensive plastics which, owing to their high impact and impact strength and high rigidity, can also be used to manufacture frame parts and / or resilient damping elements.

Advantageously, the frame parts and / or the elastically resilient damping elements can be made from a weather-resistant polyamide plastic, preferably a cycloaliphatic polyamide plastic, in glasses according to the invention.

The term polyamides is usually used as a term for synthetic, technically usable thermoplastics. Because of their excellent strength and toughness, polyamides are often used as construction materials.

Preliminary investigations have shown that transparent polyamide plastics, which are manufactured under the brand name Grilamid TR® by EMS-GRIVORY and are freely available on the market, are used particularly advantageously as a material for the production of the frame parts and / or the elastically resilient damping elements can be. Grilamid TR® has a remarkably low density compared to other transparent polymers. It is the lightest technical thermoplastic.

In particular, the polyamide plastic with the brand name Grilamid TR 90® has proven particularly advantageous for use as a material for the frame parts and / or the resilient damping elements. Grilamid TR 90® is a homopolyamide and has an exceptionally good dynamic strength: This material has a fatigue strength of more than 30 MPa and, even with an alternating bending load of +/- 50 MPa, still achieves one million alternating bending cycles when the load changes. The tensile modulus of elasticity of Grilamid TR 90® is 1600 MPa, the yield stress is approximately 60 MPa and the elongation at break is

6/16

AT 16 557 U2 2019-12-15 Austrian patent office around 6%. Its nominal elongation at break is more than 50%, which is why this material is particularly tough. In addition, the density of Grilamid TR 90® is only 1g / cm ³ . Depending on the design of the eyeglass frame or the frame parts, this selected material can be used to provide a frame device which is extremely light and weighs only about 30 g in total.

In addition to the mechanical properties such as high strength, rigidity and ductility, this plastic has high chemical resistance to cosmetics, skin perspiration and various paints. The plastic is free of plasticizers.

Thermoplastic polycarbonate plastics are mostly used as the preferred material for producing the spectacle lens, since these have high strength, impact strength, rigidity and hardness. Using suitable lacquer coatings or in combination with transparent thermoplastic polyurethanes, light, UV-light-resistant lenses can be made from polycarbonate, which are ideally suited for spectacle lenses and also for plastic optical lenses. Alternatively, other transparent plastics such as polymethyl methacrylate (short: PMMA) can also be used to manufacture the spectacle lens.

It can be particularly advantageous if, in the case of glasses according to the invention, the resilient damping elements in a wearing position of the glasses on the head of a user, starting from the respective fastening section, first against a temporal direction laterally on the head of the user and then in a nasal direction Nose of the user run out, so that in a wearing position of the glasses, the damping elements each form a lower frame section for the at least one spectacle lens without being connected to it. In this variant, the damping elements can advantageously be curved or curved, for example, and essentially follow the contour of the lower and at least partially also the lateral edge of the respective spectacle lens section, but without being attached to the spectacle lens. The greater the free length of the freely resilient or freely vibrating damping elements, the higher the damping effects can be achieved.

Starting from the fastening section, this lower frame section forms the continuation of the respective frame part, the lower frame section being spaced from the spectacle lenses and there being no direct contact with the respective spectacle lenses. This lower frame section ends at the nose pads or the respective nasal end of the spring elements.

In order to ensure a sufficient spring action in the event of a load in the event of impacts or an impact on the glasses, it may be expedient if, in the case of glasses according to the invention, the resilient damping elements each have a freely oscillating length of 60 to 100 mm, preferably 70 to 90 mm , exhibit.

When the glasses are unloaded without external impact or vibration forces, the distances between the lower edge of the at least one spectacle lens and the respective damping element can be, for example, 2 mm and for the nose pads, for example, 3 mm. In the loaded state under the influence of an external force during shaking of the glasses, the distance between the lower edge of the glasses lens and the respective damping element or the respective nose pad can be reduced to +/- 0 mm. Depending on the individual anatomy of the user, the support points of the nose pads in the wearing position, seen from the front, lie in a plane behind the at least one spectacle lens when the eyeglass wearer is wearing a delicate nose. This makes it possible for the damping elements in the vertical direction between the spectacle lens and the front of the face of the user to swing in the vertical direction even higher than to the lower edge of the spectacle lens during a load on the glasses, i.e. in a loaded wearing position while the glasses are subjected to external force can without touching the glass edges.

The following detailed description of the figures relates to the first embodiment of glasses 1 according to the invention shown in FIGS. 1 to 4. The glasses 1 shown here are designed as sports glasses and have a one-piece, continuous spectacle lens 10 made of unbreakable plastic. The spectacle lens 10 has a left spectacle lens section 11 and a right spectacle lens section 12. Fitting parts 13, 130 are molded onto a lateral end 110 of the left spectacle lens section 11, which are used for mechanical fastening with a frame device 20 or with a corresponding left frame part 21. A lower edge 111 of the left lens section 11 forms a contour section of the lens.

Mirror-symmetrically to this, the right spectacle lens section 12 has a lateral end 120, on which here fitting parts 14, 140 are formed, which are used for mechanical fastening with a frame device 20 or with a corresponding right frame part 22. A lower edge 121 of the right spectacle lens section 12 forms a contour section of the spectacle lens.

The frame device 20 comprises a left frame part 21 with a left fastening section 210, a left damping element 211 fastened thereon and a left nasal frame end 212.

8.16

AT 16 557 U2 2019-12-15 Austrian Patent Office The frame device 20 further comprises a separate right frame part 22 which is independent of the left frame part 21 and has a right fastening section 220, a right damping element 221 fastened thereon and a right nasal frame end 222 left 21 and right 22 frame parts are designed mirror-symmetrical to each other and, for example, made in one piece from a thermoplastic with the brand name Grilamid TR 90®. A nose pad 23 is attached to each of the nasal frame ends 212 and 222. These nose pads 23 are particularly advantageously equipped with an internal insert material, for example made of metal, which can be easily deformed by a user. The nose pads 23 can thus be adapted to the particular anatomy of the user's nose.

The left fastening section 210 has a left fastening recess 24, into which fastening recess 24 the fitting parts 13, 130 or contour sections arranged on the lateral end 110 of the left spectacle lens section 11 engage in the assembled position of the spectacles 1. Here, a positive and non-positive, detachable plug connection is selected for connecting the left frame part 21 to the corresponding spectacle lens section 11 of the spectacle lens 10.

Likewise, the right fastening section 220 has a right fastening recess 25, into which fastening recess 25 the fitting parts 14, 140 or contour sections arranged at the lateral end 120 of the right spectacle lens section 12 engage in the assembled position of the spectacles 1. Here, mirror-symmetrically, a positive and non-positive, releasable plug connection is also chosen for connecting the right frame part 22 to the corresponding spectacle lens section 12 of the spectacle lens 10. In the assembled state of the glasses 1, the two frame parts 21, 22 are connected to one another only with the glasses lens 10 lying between them.

On the two frame parts 21, 22, a pair of left eyeglass temples 31 and a right eyeglass temple 32 are each movably attached by means of temple hinges 33. An arrow N1 symbolizes the nasal direction N1 of the left damping element 211 - in relation to the intended wearing position of the glasses on the head of a user as “pointing towards the user's nose”. The arrow N2 symbolizes the nasal direction N2 of the right damping element 221. The variable gap distance S1 between the left damping element 211 and the lower glass edge 111 is identified by an arrow S1. Likewise, the variable gap distance S2 between the right damping element 221 and the corresponding lower glass edge 121 is marked with an arrow S1.

A direction of deflection R1 of the left damping element 211, in which it can swing freely, is symbolized by a double arrow R1.

A direction of deflection R2, in which the right damping element 221 can swing freely, is symbolized by a double arrow R2.

In the embodiment shown here, the respective damping element 211, 221 not only extends in the nasal direction N1, N2 essentially along the lower edge 111, 121 of the spectacle lens 10, but also follows the lateral curvature of the spectacle lens 10 in a temporal or lateral manner Direction T1, T2 to the respective fastening section 210, 220. The arrow T1 symbolizes the lateral direction of the release of the left damping element 211. According to the anatomical concept of "temporal" as "pointing to the temple of a user", the left damping element 211 is - starting from Fastening section 210 - first oriented in the direction of arrow T1 in a lateral direction, strictly speaking pointing away from the user's temple, laterally downward, in order to subsequently extend in the nasal direction N1 following the curved or rounded contour of the spectacle lens 10.

Conversely, the arrow T2 symbolizes the lateral direction of the release of the right damping element 221. Starting from the fastening section 220, the right damping element 221 is also initially oriented in the direction of the arrow T2 in a lateral, downward direction away from the user's temple, to then get the ge

In an unloaded wearing position P1 in the rest position of the glasses 1, as shown for example in FIG. 3, the gap distances S1, S2 between the lower edges 111, 121 of the spectacle lens 10 and the respective damping element 211, 221, for example, 2 mm and in the area between the lower edges 111, 121 and the nose pads 23, for example 3 mm.

In the loaded state under the action of an external force P2, as is illustrated, for example, in FIG. 4, the gap distances S1, S2 between the lower edges 111, 121 of the spectacle lens 10 and the respective damping element 211, 221 or the respective nose pad 23 can be reduced to +/- 0 mm. The gap distances S1, S2 are advantageously variable, which is why external forces P2 which do not act centrally on the glasses 1, but instead, for example in the form of forces from the side or obliquely from above or below, particularly effectively from the elastic damping elements 211, 221 can be damped. For example, in a loaded wearing position P2, in which the external force acting on the glasses 1 mainly acts on the left frame part 21, the left gap distance S1 can briefly be significantly smaller than the right gap distance S2. The two damping elements 211, 221 can advantageously be deflected independently of one another in order to be able to dampen vibrations of the glasses 1 in the best possible way and thus to ensure that the glasses wearer is very comfortable to wear.

5 shows a second embodiment of glasses 1 according to the invention with a one-piece spectacle lens 10 and with two frame parts 21, 22 fastened to the spectacle lens 10, the nasal frame ends 212, 222 of the damping elements 211, 221 being connected to an elastic middle piece 26 , The elastic middle piece 26 is here, for example, a soft silicone tube section which is fastened to the nasal frame ends 212, 222 and which enables the sports glasses to be held in a particularly secure, non-slip manner in the wearing position on the head of a user.

6 shows a third embodiment of glasses 1 according to the invention with two separate glasses 11, 12 which are connected to one another by means of two nose pieces 19. Frame parts 21, 22 are fastened to the spectacle lenses 11, 12, the nasal frame ends 212, 222 of the damping elements 211, 221 being connected to a central piece 26.

Likewise, in a further, not explicitly shown embodiment of a pair of glasses 1 according to the invention with two separate glasses 11, 12, such a center piece 26 may also be missing. In this design variant, classic glasses 1 with separate glasses lenses 11, 12 can be combined with the advantageous effects of the frame parts 21, 22 equipped with the damping elements 211, 221.

FIG. 7 shows the glasses 1 shown in FIG. 3 in an unloaded wearing position P1 in the rest position of the glasses 1 together with the contour of the head of a spectacle wearer, indicated by dashed lines. The gap distances S1, S2 here in the unloaded wearing position are, for example, between 2 mm and 3 mm.

FIG. 8 shows the glasses 1 shown in FIG. 4 in a loaded wearing position P2 during an external force action, which is symbolized as arrow P2, together with the contour of the head of a spectacle wearer, indicated by dashed lines. The gap distances S1, S2 are here, for example, for a short time +/- 0 mm when viewed from the front in the loaded wearing position. Because of the comparatively narrow, delicate nose of the spectacle wearer, the nose pads 23 lie somewhat arched to the face of the wearer behind the spectacle lens 10 on the nose. This can also be seen from the side view of FIG. 9. 8, the damping elements 211, 221 and the nose pads 23 do not touch the lower edges 111, 121 of the spectacle lens even during the external force P2
