Description

Technical Field

[0001] The invention relates to a selection aid for selecting spectacle lenses. Background Art

[0002] Spectacle lenses are usually selected by medical history, in which a trained optician determines the indicators of the type of spectacle lenses suitable for the respective customer based on a catalog of questions. The purpose of the medical history is to cover all possible indicators necessary to propose the most suitable type of spectacle lenses. Therefore, the medical history is usually very comprehensive and time-consuming. However, medical history indicators that specify the order or weight of questions to be asked to the customer are not common. In addition, there are many indicators, especially those related to the design, which are difficult to identify, especially for new customers. Finally, a high level of expertise and experience is required to obtain a thorough medical history. Although trained opticians have sufficient expertise and experience, they are not present in every store that provides glasses, especially internationally. Therefore, not every customer consultant can make good use of the medical history means currently available, especially the EDP program and medical history questionnaire for medical history. Summary of the invention

[0003] It is therefore an object of the present invention to provide a selection aid for selecting spectacle lenses which is easy to use even without extensive expert knowledge.

[0004] This object is achieved by a selection aid having the features of claim 1. The dependent claims relate to advantageous developments of the invention.

[0005] The concept on which the invention is based is that, based on two disks that can be rotated relative to each other about an axis of rotation, it is possible even for unskilled personnel to define selection criteria based on simple questions to the customer, which selection criteria can be used as a basis for reliably obtaining a recommendation for the type of spectacle lenses to be selected. By rotating the second disk relative to the first disk, a selection area with a central selection segment provided with customer-specific indicators can be selected. The latter is assigned questions, in particular questions about the age of the customer. Each central selection segment then has an age range, wherein the age ranges do not overlap with each other. The two disks are rotated relative to each other so that the second disk releases a selection area in which the correct indication about the age of the customer is provided in the central selection segment of the selection area. From here on, in a radial direction, i.e. in a direction away from the axis of rotation, the questions assigned to the further selection segments are answered one after another and the corresponding partial selection segment of the selection segment to which the question is assigned is selected. Finally, a partial selection section of the last selection section is reached, which adjoins the recommendation section in radial direction, and which contains recommendations for the type of spectacle lenses to be selected and may also contain recommendations for near vision additions for the spectacle lenses, which may in particular include recommendations for changing the near vision additions of the customer's current spectacle lenses. In particular, one of the questions assigned to the further selection section may relate to the customer's visual challenges or difficulties, while another question assigned to the further selection section may relate to the spectacle lenses currently used by the customer. The partial selection section of the relevant further selection section then specifies the answers to the respective questions, which the user may select in order to finally reach the appropriate recommendation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The invention is explained in more detail below based on exemplary embodiments schematically shown in the accompanying drawings. In the drawings:

[0007] Figure 1a to Figure 1d shows a front view of a selection aid, wherein the second disc has four different positions relative to the first disc, and

[0008] Figure 2 Shown according to Figure 1a to Figure 1d Rear view of the selection aid. DETAILED DESCRIPTION

[0009] The selection aid 10 shown in the drawings has a first disk 12 of circular shape, to which a second disk 14 of the same diameter is rotatably connected about an axis of rotation 16. The two disks 12, 14 are arranged concentrically, wherein the second disk 14 is arranged on a selection area 18 of the first disk and covers a large part thereof. The selection area 18 is subdivided into four selection areas 20a to 20d, each of which is of equal size and extends at a center point angle of 90°. The second disk 14 has the shape of a circular sector, which extends at a center point angle of 270° and thus leaves an area corresponding to one of the selection areas 20a to 20d in terms of its shape and size. Therefore, the two disks 12, 14 can be rotated relative to each other so that one of the selection areas 20a to 20d is always visible, while the other selection areas 20a to 20d are covered by the second disk 14 and are not visible. In addition, a cover disk 22 is fixedly connected to the second disk 14, which is arranged on the outer side 24 of the second disk 14 facing away from the first disk 12. The cover disc in turn has a circular shape and is concentric with respect to the first disc 12 and the second disc 14, so that its centre point also lies at the axis of rotation 16. The applicant's logo is arranged on the cover disc 22, through which the axis of rotation 16 also extends.

[0010] The selection areas 20a to 20d each have a central selection section 26 in the shape of an annular sector, the inner boundary line 28 of which is in the shape of an arc coincides with the outline of the cover disk 22. The central selection sections 26 are each provided with a different customer age range; Figure 1a The middle age group is between 20 and 29 years old. Figure 1b The middle age group is between 30 and 39 years old. Figure 1c The age range is 40 to 49 years old, and Figure 1d On the outer side 24 of the second disk 14, the central selection section 26 is assigned, by corresponding positioning relative to the axis of rotation 16, a first question 27 about the customer's age (How old are you? After the question asked by the customer consultant has been answered, the first disk 12 and the second disk 14 are rotated relative to each other so that the selection areas 20a to 20d having the correct answer to the question are visible, while the other selection areas 20a to 20d are hidden by the second disk 14.

[0011] In the radial direction 30 indicated by the arrow, i.e. away from the axis of rotation 16, in each selection area 20a to 20d, an additional first selection section 32 is adjacent to the central selection section 26, said additional first selection section being further subdivided into four equally sized partial selection sections 34, each of which is in the shape of an annular sector. At a corresponding distance from the axis of rotation 16, the second disc 14 has a second question 36 assigned to the additional first selection section 32, said second question being related to the visual challenges or difficulties of the customer (do you experience the following visual challenges ). Each partial selection section 34 of the further first selection section 32 contains possible answers, wherein the arrangement of these partial selection sections 34 of the further first selection section 32 is the same in each selection area 20a to 20d. The customer informs the customer advisor which prescribed answer best suits the question (none, or eyestrain, or near vision discomfort, or near vision blur). In the radial direction 30, an additional second selection section 38 is adjacent to the further first selection section 32, the shape of the further second selection section then being an annular sector. Continuing from the answer to the second question 36, the customer advisor asks the customer a third question 40, which is assigned to the additional second selection section 38 by a corresponding arrangement on the outer side 24 of the second disc 14 (What is your current lens solution? ) and relates to the current spectacle lens solution or the current spectacle lens type. Each partial selection segment 34 of the further first selection segment 32 is assigned three partial selection segments 42 of the further second selection segment 38, which are to be selected based on the correct answer to the third question 40 and relate to the current spectacle lens solution or the current spectacle lens type, respectively. The answers SV (for single vision lenses), DIG (for digital lenses) and PAL (for progressive lenses) are available for selection. Once a suitable partial selection segment 42 of the further second selection segment 38 has also been selected, the answer to the question about the suitable spectacle lens type can be read out in a recommendation segment 44, which in turn is in the shape of an annular sector and is immediately adjacent to the selected partial selection segment 42 of the further second selection segment 38 in the radial direction 30. In this case, it is possible that a suitable spectacle lens type is mentioned in the recommendation segment 44, a recommendation is additionally given for the refractive power of the spectacle lens in the near vision range (addition light in near vision), or there may be no explicit recommendation, which is indicated by "further investigation required". An explanatory text 46 on the outer side 24 of the second disk 14 , which is assigned to the recommendation section 44 by a corresponding distance from the rotation axis 16 , clarifies that the text in the recommendation section 44 is a spectacle lens recommendation.

[0012] Figure 2It is also shown that operating instructions for the selection aid 10 are printed on a rear side 48 of the first disk 12 facing away from the second disk 14 .

[0013] The exemplary embodiment shown assigns questions about the age of the customer to a central selection section 26, wherein four possible age ranges can be selected. Needless to say, this should be considered as merely an example. On the one hand, more or fewer age ranges can be selected by corresponding extensions of the selection areas 20a to 20d. In this regard, each selection area 20a to 20d extends over a center point angle of 120° in the case of three selectable age ranges, over a center point angle of 72° in the case of five selectable age ranges, over a center point angle of 60° in the case of six selectable age ranges, etc. On the other hand, the first question 27 can also relate to different indicators, and the order of the questions can likewise be a different order.
