[0039] As known from the background art, the progressive lens in the prior art has the problem of high difficulty of adaptive training.
[0040] REFERENCE Figure 1 , a structural schematic view of a lens of a progressive lens is shown.
[0041] The lens of the progressive lens has a far vision zone 11 and a near vision zone 12. The lens of the far vision zone 11 has a far vision power suitable for far vision, and the lens of the near vision zone 12 has a near vision power suitable for near vision. In order to realize the respective powers of the far vision zone 11 and the near vision zone 12, the lens of the progressive lens has a vignetting zone.
[0042] Specifically, as shown in the lens in Figure 1 The far vision zone 11 and the near vision zone 12 are respectively located in the upper and lower parts of the lens, and the vignetting zones are located on both sides of the line connecting the far vision zone 11 and the near vision zone 12, and are respectively a vignetting zone 13a and a vignetting zone 13b.
[0043] The far vision zone 11 and the near vision zone 12 are the best vision zones of the progressive lens in use. When the line of sight falls in the vignetting zone, the object image is deformed, and the swimming effect is generated. The smaller the vignetting degree is, the closer to the far vision zone 11 or the near vision zone 12. The more serious the vignetting degree is, the closer to the edge of the lens. Therefore, when the head is rapidly rotated, the influence of the vignetting zone will be more obvious.
[0044] During the fitting of the progressive lens, the user needs to spend a long time to learn how to correctly use it: when looking far, the line of sight falls in the far vision zone 11 of the upper part of the lens; when looking near, the line of sight falls in the near vision zone 12 of the lower part of the lens; when looking left and right, the head rotation is used instead of the eyeball rotation to avoid the line of sight falling in the vignetting zone. In addition, there is a transition zone 14 between the far vision zone 11 and the near vision zone 12. The transition zone 14 also has slight vignetting. When using the transition zone 14 to look near, some users may have visual fatigue.
[0045] When learning to use the progressive lens, the user needs to learn to control the position of the line of sight. Therefore, the fitting process of the progressive lens has quite high requirements on the understanding ability and action ability of the user and the matching degree.
[0046] However, there is no obvious distinction between different regions of the lens of the progressive lens, and the user cannot clearly and directly distinguish the specific range and position of different regions. Especially in the initial stage of using the progressive lens, when the user does not fully master the use method, the line of sight is easy to fall in the vignetting zone, and the user is easy to have dizziness, nausea and other discomfort; the discomfort in the initial stage will make the user have resistance, which will prolong the learning and adaptation time, and may affect the use rate of the progressive lens, so that the progressive lens is idle.
[0047] On the other hand, when teaching the use method, the fitter needs to observe whether the line of sight of the user falls in the correct region. Therefore, the fitting process of the progressive lens has quite high requirements on the expression ability and guiding ability of the fitter, and the training cost of the fitter is higher and the period is longer.
[0048] Therefore, in the fitting process of the progressive lens, even if the vision examination, product selection, lens correction and the like are correct, the high-difficulty adaptive training seriously affects the promotion and popularization of the progressive lens.
[0049] To solve the technical problem, the utility model provides a kind of training patch of progressive lens.The training patch has the limit area for identifying the astigmatic zone of the lens.The limit area can identify the astigmatic zone in the lens of progressive lens, can remind the range and position of astigmatic zone in adaptive training, make user better control sight line position, can effectively reduce the difficulty of adaptive training of progressive lens, be conducive to the promotion and popularization of progressive lens.
[0050] To make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below with reference to the drawings.
[0051] Reference Figure 2 , shows the structure schematic diagram of some embodiments of the training patch of the utility model progressive lens.
[0052] The lens of the progressive lens ( Figure 2 With dotted line) has astigmatic zone.The training patch includes: limit area, the limit area is suitable for being set on the surface of the astigmatic zone of the lens to identify the astigmatic zone.
[0053] The training patch is suitable for being set on the surface of the lens of the progressive lens to identify the astigmatic zone, so as to remind the position and range of astigmatic zone in the process of adaptive training, assist user to learn sight line control method, reduce the difficulty of adaptive training.
[0054] In some embodiments of the utility model, the limit area identifies the astigmatic zone by reducing the transmittance.When the training patch is set on the lens, the limit area is located on the surface of the astigmatic zone, and the limit area reduces the transmittance of light in the astigmatic zone by blocking the transmission of light, so as to achieve the effect of identifying the astigmatic zone.
[0055] In some embodiments, the transmittance of the limit area to light of a preset waveband is greater than the transmittance of light outside the preset waveband.Specifically, the limit area has higher transmittance to light of a preset waveband, and the transmittance of light outside the preset waveband is lower.The preset waveband can be light of a certain color within the visible light waveband range (i.e., the wavelength range is approximately within 400nm to 700nm), for example, the preset waveband can be red light (i.e., the wavelength range is approximately within 620nm to 750nm), green light (i.e., the wavelength range is approximately within 500nm to 570nm) or yellow light (i.e., the wavelength range is approximately within 570nm to 590nm) and the like.
[0056] Specifically, such as Figure 2 In some embodiments shown, the lenses of the graduated lenses ( Figure 2 (Shown as dashed lines) It has two astigmatic regions. The restriction region of training patch 110a (not shown in the figure) is located in one of the astigmatic regions, and the restriction region of training patch 110b (not shown in the figure) is located in the other astigmatic region. Both the restriction regions of training patch 110a and training patch 110b allow red light to pass through, but block light of other wavelengths other than red light from passing through. The location and extent of the astigmatic regions are marked in red.
[0057] It should be noted that the preset wavelength band can be a part of the visible light band or the entire visible light band. In some embodiments, the preset wavelength band is the entire visible light band, that is, the transmittance of the restricted area to light in the entire visible light band is low; therefore, the restricted area is displayed as black, that is, the restricted area can also be marked with black astigmatism.
[0058] When the training patch is placed on the lens surface, users can intuitively understand the location and range of the astigmatic area through the difference in transmittance, and can check whether the lens fitting is successful. After the glasses are corrected, the optometrist can intuitively observe whether the correction of the glasses is in place and whether the user wears them properly. The use of the training patch can effectively reduce the guidance cost of optometrists and effectively reduce the difficulty of user adaptation training, which is conducive to the promotion and popularization of progressive lenses.
[0059] It should be noted that the method of marking astigmatic regions by making different wavelengths of light have different transmittances (i.e., by color) is only one example. In other embodiments of this utility model, the training patch may also reduce transmittance by making light across the entire wavelength range reflect or refract.
[0060] refer to Figure 3 The diagram shows structural schematics of some other embodiments of the training patch for the graduated focus glasses of this invention.
[0061] Unlike the aforementioned embodiments, in some embodiments, the restricted region causes light to be reflected or refracted across the entire wavelength range.
[0062] In some embodiments, the confinement region reflects or refracts at least a portion of the light. In some example embodiments, the confinement region scatters at least a portion of the light, thereby reducing the light transmittance of the confinement region; when the training patch is disposed on the surface of the lens, the transmittance of the astigmatic region differs from the transmittance of other regions, thereby achieving representation of the astigmatic region. Specifically, the confinement region may have a frosted structure to scatter at least a portion of the light.
[0063] In some embodiments of the utility model, the degree of the light transmittance reduction of the restriction area is related to the degree of astigmatism of the astigmatism area. Specifically, the more serious the degree of astigmatism of the astigmatism area is, the greater the degree of the light transmittance reduction of the corresponding restriction area is. The corresponding restriction area refers to the restriction area arranged on the astigmatism area.
[0064] In some embodiments, the light transmittance of the inner side of the restriction area is greater than that of the outer side of the restriction area, wherein the inner side of the restriction area corresponds to one side of the usage area of the lens, and the outer side of the restriction area corresponds to the edge of the lens.
[0065] In the lens of the progressive addition lenses, the closer to the near vision area or the distance vision area, the weaker the degree of astigmatism is, and the closer to the edge of the lens, the more serious the degree of astigmatism is. The light transmittance of the restriction area is determined based on the degree of astigmatism of the astigmatism area, which not only can identify the position and range of the astigmatism area, but also can effectively reflect the degree of astigmatism of different positions of the astigmatism area, and is more conducive to helping the user control the line of sight. Specifically, as shown in some embodiments, Figure 3 the light transmittance of the restriction area gradually decreases along the direction from the inner side to the outer side.
[0066] It should be noted that the inner side of the restriction area corresponding to one side of the usage area of the lens means that the inner side of the restriction area is suitable to be arranged on one side of the usage area of the lens, and the outer side of the restriction area corresponding to the edge of the lens means that the outer side of the restriction area is suitable to be arranged on one side of the edge of the lens.
[0067] Specifically, as shown in the figure, Figure 3 the inner side 212a of the restriction area 211a of the training patch and the inner side 212b of the restriction area 211b of the training patch are close to the near vision area and the distance vision area of the lens, the corresponding position of the astigmatism area has a weak degree of astigmatism, and the light transmittance of the inner side 212a of the restriction area 211a of the training patch and the inner side 212b of the restriction area 211b of the training patch is also relatively high; the outer side 213a of the restriction area 211a of the training patch and the outer side 213b of the restriction area 211b of the training patch are close to the edge position of the lens, away from the near vision area and the distance vision area of the lens, the corresponding position of the astigmatism area has a serious degree of astigmatism, and the light transmittance of the outer side 213a of the restriction area 211a of the training patch and the outer side 213b of the restriction area 211b of the training patch is also relatively low.
[0068] Referring to Figure 4 , the structure schematic diagram of another some embodiments of the training patch of the progressive addition lenses of the utility model is shown.
[0069] Different from the foregoing embodiments, in some embodiments, the lens of the progressive addition lens has at least two astigmatic zones, and the at least two astigmatic zones are separated from each other; the training patch has at least two limiting zones, and the training patch further has a connecting zone connecting the different limiting zones.
[0070] In some embodiments of the utility model, the training patch has a first limiting zone and a second limiting zone; the training patch further comprises a connecting zone between the first limiting zone and the second limiting zone. The different limiting zones are connected through the connecting zone, so that the limiting zones corresponding to the separated astigmatic zones are connected into a piece, which can effectively reduce the assembly difficulty of the training patch and effectively improve the assembly precision of the training patch.
[0071] In some embodiments, the transmittance of the connecting zone is higher than that of the limiting zone. The transmittance of the connecting zone is higher than that of the limiting zone to avoid the influence of the connecting zone on the use of the area of the lens other than the astigmatic zone.
[0072] In some embodiments, the lens of the progressive addition lens has a near vision zone, a distance vision zone and a transition zone; the connecting zone corresponds to at least one of the near vision zone, the distance vision zone and the transition zone. In some specific embodiments, the transmittance of the part of the connecting zone corresponding to at least one of the near vision zone and the distance vision zone is higher than that of the connecting zone corresponding to the transition zone. In the lens of the progressive addition lens, the transition zone is a transition channel between the near vision zone and the distance vision zone. The lens of the transition zone also has slight astigmatism. Some users are prone to visual fatigue when using the transition zone to look near. The transmittance of the part of the connecting zone corresponding to the transition zone is different from that of the part of the connecting zone corresponding to at least one of the near vision zone and the distance vision zone, which can help the user to identify the position and range of the transition zone in the adaptive training process, so as to better distinguish the distance vision zone and the near vision zone and better adapt and control the use of the transition zone.
[0073] It should be noted that the connecting zone corresponding to at least one of the near vision zone, the distance vision zone and the transition zone means that the connecting zone is suitable to be arranged on the surface of at least one of the near vision zone, the distance vision zone and the transition zone. For example, the connecting zone corresponding to the near vision zone means that the connecting zone is suitable to be arranged on the surface of the near vision zone; the connecting zone corresponding to the transition zone means that the connecting zone is suitable to be arranged on the surface of the transition zone.
[0074] In some embodiments, the connecting zone corresponding to at least one of the near vision zone, the distance vision zone and the transition zone further comprises that the shape of the connecting zone is the same as that of at least one of the near vision zone, the distance vision zone and the transition zone.
[0075] For example, the connection region corresponding to the near-use region can also mean that the connection region is suitable to be arranged on the surface of the near-use region, and the shape of the connection region is the same as the shape of the near-use region; the connection region corresponding to the transition region can also mean that the connection region is suitable to be arranged on the surface of the transition region, and the shape of the connection region is the same as the shape of the transition region.
[0076] In some embodiments, the training patch has the same shape as the lens shape. Specifically, the training patch can cover the entire surface of the lens. Arranging the shape of the training patch to be the same as the shape of the lens can effectively reduce the manufacturing difficulty and assembly difficulty of the training patch, can reduce the presence of the training patch as much as possible, and can effectively avoid the additional interference of the training patch on the line of sight.
[0077] Specifically, as shown in some embodiments, Figure 4 The training patch has a first limiting region 311a and a second limiting region 311b; the connection region is located between the first limiting region 311a and the second limiting region 311b. The connection region includes a first connection sub-region 311c, a second connection sub-region 311d, and a third connection sub-region 311e, which correspond to the transition region, the distance-use region, and the near-use region of the lens, respectively.
[0078] Specifically, the first connection sub-region 311c is suitable to be arranged on the transition region of the lens, and the shape of the first connection sub-region 311c is the same as the shape of the transition region; the second connection sub-region 311d is suitable to be arranged on the distance-use region of the lens, and the shape of the second connection sub-region 311d is the same as the shape of the distance-use region; the third connection sub-region 311e is suitable to be arranged on the near-use region of the lens, and the shape of the third connection sub-region 311e is the same as the shape of the near-use region.
[0079] It should be noted that in some embodiments of the utility model, the training patch further comprises: a hidden marking point, which is suitable to cooperate with the hidden marking point of the lens to position. The hidden marking patch is used to determine the position of the training patch on the lens. In some embodiments, the training patch has at least two hidden marking points to ensure the positioning accuracy of the position of the training patch on the lens. Specifically, as shown in Figure 4 The training patch has a hidden marking point 321 and a hidden marking point 322.
[0080] Correspondingly, the utility model also provides a lens structure. The lens structure comprises: a progressive lens; a training patch, which is located on the surface of the progressive lens, and the training patch is the training patch of the utility model.
[0081] The training sticker is the training sticker of the utility model. The specific technical scheme of the training sticker can refer to the foregoing embodiment of the training sticker. The training sticker can identify the astigmatic zone of the progressive focus lens, thereby helping the user to learn the line of sight control in the adaptability training of the progressive focus lens, and reducing the adaptability training difficulty of the progressive focus lens.
[0082] In some embodiments of the utility model, the restriction area of the training sticker is consistent with the shape of the astigmatic zone of the progressive focus lens. The consistency of the range of the restriction area of the training sticker and the astigmatic zone of the progressive focus lens means that the coverage range of the restriction area on the surface of the progressive focus lens is the same as the range of the astigmatism exceeding the preset value on the progressive focus lens.
[0083] In some embodiments, the maximum range of the restriction area of the training sticker is the same as the astigmatic zone of the progressive focus lens. The maximum range of the restriction area and the astigmatic zone is the same to obtain better training effect and ensure the training results of the user.
[0084] In some embodiments of the utility model, the training sticker is located on the outer surface of the progressive focus lens. The progressive focus lens has an inner surface facing the eye and an outer surface facing away from the eye during use, and the training sticker is arranged on the outer surface.
[0085] In some embodiments of the utility model, the training sticker is detachably attached to the surface of the progressive focus lens. The training sticker can be removed after the training is completed, and the training sticker will not affect the normal use of the progressive focus lens, so as to reduce the influence of the training sticker on the use of the lens as much as possible.
[0086] In some embodiments, the training sticker is repeatedly detachably attached to the surface of the progressive focus lens. The training sticker can be reattached when the training effect is not good, and the adaptability training can be repeatedly performed.
[0087] Specifically, in some embodiments, the training sticker and the surface of the progressive focus lens are attached to each other by electrostatic action.
[0088] In addition, the utility model also provides a progressive focus lens.
[0089] The progressive focus lens comprises a lens structure, and the lens structure is the lens structure of the utility model. The lens structure is the lens structure of the utility model. The specific technical scheme of the lens structure can refer to the foregoing embodiment of the lens structure.
