Definitions
- the invention relates to spectacles and a use of a pair of spectacles with a spectacle frame and an additional frame according to the preamble of claim 1 and of the claim 9.
- Such glasses with a spectacle frame and an additional rack can be placed on it are known per se. They are in particular ver used that the glasses frame with usually ground vision correcting discs as a visual aid and the additional part as sunglasses equipped with tinted windows without vision correction. Thus, the user is largely protected without changing the glasses and without visual impairment against solar radiation and brightness.
- progressive lenses are known, in each of which a special le spectacle lens with different refractive powers for remote and near correction (bifocal) or for remote, middle and close correction (multifocal) is used, with a continuous grinding on each of the discs is trained to see it in virtually all distances between the different far and near points sharp.
- the user has at least the same tendency for each distance but only in a narrow field of vision the correct vision correction (especially if the difference in vision correction between distance and near proximity is large), which is a constant adjustment of the Au Studentssraum and the head posture of the user.
- the transitions between these areas are fluid and outwardly not visible.
- the over- The transition between distance and near-range is also referred to as a progression zone, where the downward spherical effect continuously increases until the near addition is reached.
- the spectacle lens In the progression area, the spectacle lens has the corrective effect for the ametropia and the additional effect for seeing at medium distances.
- the width of the progression zone depends on the effect of the near additive. The disadvantage is that this shorter the progression zone, the shorter it is and the higher the addition between near and far.
- interview glasses also referred to as indoor or computer workstation goggles
- interview glasses typically optimally cover the mean visual range between 50 and 100 to 400 cm, wherein any distance variants are conceivable, depending on the user's need.
- the use of such glasses inevitably leads to the fact that the user has at least two glasses and this always needs to change as needed.
- the invention has for its object to design a pair of spectacles of the genus he mentioned in such a way that the user with her in a simple way between the different distance ranges can change and the vision corrections the need for effective Benut tion when using the glasses frame without or with additional frame can be adjusted as desired.
- the panes of the spectacle frame are progressive lenses for the purpose of correcting vision for different distance ranges in order to achieve maximum or clear visual acuity at least to a distance range
- the discs of the additional frame are configured as Einwirkschparn or as progressive lenses, which in combination with the lenses of the spectacle frame cause visual corrections that are specifically tailored to the needs of the user.
- the progressive lenses of the spectacle frame can be designed specifically for maximum vision in the far vision area or in the middle to near distance, while they do not have the full corrective effect at medium to near distance or in the far vision area.
- Dispensing with the voilkorrigierende effect in the middle and close range brings for the user with a considerable comfort gain, since in this way the otherwise strong differences in the visual correction caused by the gliding disc are largely eliminated even with little change in Momentwinkeis.
- This gain in comfort is especially important for the user and is useful when the corrections required for the near-vision range deviate relatively strongly from the corrections necessary for the far-sighted area.
- the additional frame and its unifocal or cast lens discs for example, a further correction can be made in such a way that in the combination of the discs of the spectacle frame with the discs of the additional frame, the near and middle visual range is considerably improved. Tert and the instantaneous angle of the user is significantly increased for these areas, which brings a great comfort for the user when looking in the near and mid-light area with it.
- the user only has to carry a single spectacle frame and this additional frame instead of two separate spectacle frames, and he can thus insert this thin and lightweight additional frame in a trouser pocket, shirt pocket or shirt pocket and on the carrying of a separate utensil , such as a handbag, for an additional glasses frame.
- a user can also save considerably on the cost of acquiring such an eyewear according to the invention, since he does not need two eyeglass frames, as for example when using an outdoor and an interview broth, and in the case of the discs, in particular those of the additional frame, Often, simpler and thus cheaper variants can be used.
- he can easily switch between visibility by placing or removing this auxiliary frame with a simple movement. If, for example, he alternately wants to look at the screen of his laptop, mobile phone or the like directly in front of him, on the other hand at a desktop screen in a viewing distance of 50 to 100 cm and also at a certain distance, for example on a screen its instantaneous angle is not restricted as in the known casting or trifocal disks. Likewise, he does not have to constantly change whole eyeglass frames, as he has to handle this, for example, when using an indoor or interview glasses. He can always use the glasses frame without Wear changes and simply place the additional frame on the spectacle frame with a quick hand movement or remove it.
- Such spectacles according to the invention are particularly suitable for persons who have visual disturbances in long, medium and short-sightedness and thus require corrective spectacles for the distance, middle and near vision.
- Fig. 1 is a perspective plan view of an inventive
- FIG. 2 shows a perspective top view of the separate spectacle frame according to FIG. 1;
- Fig. 3 is a front perspective view of the non-attached to the rack.
- Fig. 1 shows a pair of glasses 10 with a spectacle frame 11 and on the SEM front removably mounted additional frame 20 each with two consisting of a transparent material discs 12, 22, such as glasses.
- the spectacle frame 11 consists on herkömmli che way of a discs 12 holding the socket 13 with a central connecting part 17, both sides of a joint 14, depending on a pivotally mounted bracket 15 for the support in the ears and support elements 16 for supporting the glasses on the nose.
- This version 13 with the brackets 15 can be installedstaitet according to requirements with any shape of different materials and sizes.
- Accordingly adapted to the discs 12, 22 may be formed ge, which may consist of glass, plastic, a combination of these materials or other materials.
- the discs 12, 22 of both the spectacle frame 11 and the additional frame 20 are each provided with vision corrections, such that they have a refractive effect, which is adapted to the vision of the user and with these the desired visual acuity, in particular for a Nah- , Remote and possibly a middle distance range is made possible.
- the discs 12 of the spectacle frame 11 are configured as sliding vision discs for vision corrections for different distance ranges to achieve respectively maximum or distinct visual acuity to at least one distance range, while the discs 22 of the auxiliary stem 20 are single-vision or sliding vision discs are configured, which in combination with the discs 12 of the spectacle frame 1 1 effect vision corrections that are specifically tailored to the needs of the user.
- the progressive lenses of spectacle frame 1 1 can be spe- cial! be designed for maximum vision in the far vision area, while in the middle to near distance they do not have the fully corrective effect.
- the deviation of the compensation of the maximum to distinct or not fully corrected visual acuity with the vision correction in the near, middle and / or long-distance range of the discs 12 of the spectacle frame 11 o- that of their combination with the discs 22 of the auxiliary part 20 is fixed to a certain amount of the selectable correction powers.
- near vision correction at maximum vision can be + 1.5 diopters, while the effective correction is only + 0.75, which is 0.75 diopters less.
- the discs 12, 22 are suitably ground and the discs are thus designed as lenses.
- the disks could also be cast and consist of different materials, possibly also as tinted disks, or those which, in the event of high incidence of light, for example when it is sunny, cause a fouling in a known manner.
- the discs overlap 22 of the set frame 20 to the discs 12 of the eyeglass frame 11, i. they are the same size, so that the user can take advantage of his full Magnoliawin angle.
- the discs 22 extend to the discs 12 approximately or exactly parallel to each other and there is a lower
- FIG. 2 shows the spectacle frame 11 and FIG. 3 the auxiliary frame 20 separated.
- a user can only wear the spectacle frame 11 with the casting lenses if he has to change between wide, middle and near vision.
- the additional frame 20 according to FIG. 3 is advantageously made of a lightweight thin material and consists of ring-shaped or similarly shaped socket parts 23, the discs 22 held by these, a connecting member 24 and hook-shaped fastening elements 25, 26, as well as this in Fig. 1 can be seen.
- This additional frame 20 is characterized in that this formed as St16lein connecting member 24 is formed on the upper side slightly bo genförmig and resilient. If it is now to be placed on the eyeglass frame 11, it can be caused by a slight finger pressure from the top of the connecting member 24, that soel be stretched and thus the frame part 23 with the discs are pushed apart from each other something. Thus, these hook-shaped fastening elements 25, 26 mounted in pairs on the outside of the socket parts 23 can be pushed outwards over the socket 13 and when the finger pressure is released on the rod it springs back into the bent state as shown and Sunglasses 23 move back towards each other and thus Umklam numbers these fasteners 25, 26, the socket 13, so that a rigid connection between them arises.
- the additional frame 20 is first hooked on one side of the eyeglass frame 11, then stretched by pressure and train and on the side is also hooked on the side, and it can be hooked on both sides and then held on both sides is.
- the discs of the spectacle frame or the additional frame could also be executed with other corrections on the left side than on the right side, especially if the user has different vision assets from the left to the right eye.
- the attachment of the additional frame on the spectacle frame could be designed differently, such as by at least one magnet as a fastener instead of these hooks, or by a plugging or by clips.
- the discs could touch one another in the attached state.
- the discs of the additional frame could cover only a part, for example, the lower part of the discs of the spectacle frame. Since they would be smaller in size than the latter slices.
