Description
Technical Field
[0001] This disclosure relates to the field of ophthalmic photobiological modulation (PBM) technology, and particularly to an optical system and electronic device for improving eye health. Background Technology
[0002] In astigmatism correction programs, fixed spherical, cylindrical, and axis angles are typically determined based on refraction results and then embedded in custom-made lenses. However, when these lenses are integrated into vision intervention devices, their fixed optical parameters are difficult to adapt to the differences in astigmatism parameters among different users. Summary of the Invention
[0003] This disclosure aims to address, at least to some extent, the aforementioned technical problems.
[0004] To achieve the above objectives, an optical system for improving eye health is proposed according to a first aspect of this disclosure. The optical system includes: a ring beam generating component for forming a ring beam; a compensation and adjustment component for compensating and adjusting the ring beam so that the adjusted ring beam is imaged on the retina of a user's eye; a first cylindrical lens; a second cylindrical lens, wherein the first cylindrical lens and the second cylindrical lens are fitted together, and the axial directions of the first cylindrical lens and the second cylindrical lens are perpendicular to the line of sight of the user's eye, and the optical center points of the first cylindrical lens and the second cylindrical lens are coaxial with the pupil center of the user's eye; a controller for determining a target value of the intersection angle between the first cylindrical lens and the second cylindrical lens based on the astigmatism parameters of the user's eye; a transmission component for rotating the axial direction of at least one of the first cylindrical lens and the second cylindrical lens according to the target value, so that the intersection angle between the axial directions of the first cylindrical lens and the second cylindrical lens matches the target value; and the first cylindrical lens and the second cylindrical lens for sequentially transmitting the adjusted ring beam through the first cylindrical lens and the second cylindrical lens to the user's eye.
[0005] To achieve the above objectives, a second aspect of this disclosure provides an electronic device, including the optical system disclosed in the first aspect of this disclosure.
[0006] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:
[0007] The controller determines the target value of the intersection angle between the first and second cylindrical lenses based on the user's astigmatism parameters. According to the target value, it rotates at least one of the first and second cylindrical lenses along its axis to match the intersection angle between their axes with the target value. The annular beam generated by the annular beam generation component is then sequentially transmitted through the compensation and adjustment component, the first cylindrical lens, and the second cylindrical lens to the user's eye. Thus, by combining the user's astigmatism parameters with the adjustment of the intersection angle between the first and second cylindrical lenses, the optical system adapts the intersection angle between the first and second cylindrical lenses to the user's astigmatism parameters. This allows the optical system to meet the needs of users with different astigmatism parameters, improving its adaptability.

[0011] An optical system and electronic device for improving eye health according to embodiments of the present disclosure are described below with reference to the accompanying drawings.
[0012] Figure 1 This is a schematic diagram of the structure of an optical system according to an embodiment of the present disclosure.
[0013] like Figure 1 As shown, the optical system 100 of this embodiment may include a ring beam generating component 110, a compensation and adjustment component 120, a first cylindrical lens 130, a second cylindrical lens 140, a controller 150, and a transmission component 160, wherein: Ring beam generating component 110 is used to form a ring beam.
[0014] The compensation adjustment component 120 is used to compensate and adjust the ring beam so that the adjusted ring beam is imaged on the retina of the user's eye 200.
[0015] The first cylindrical lens 130 and the second cylindrical lens 140 are fitted together, and the axial direction of the first cylindrical lens 130 and the second cylindrical lens 140 is perpendicular to the line of sight of the user's eye 200. Furthermore, the optical center point of the first cylindrical lens 130 and the second cylindrical lens 140 is coaxial with the center of the pupil of the user's eye 200.
[0016] The controller 150 is used to determine the target value of the intersection angle between the first cylindrical lens 130 and the second cylindrical lens 140 based on the astigmatism parameters of the user's eye 200.
[0017] The transmission assembly 160 is used to drive at least one of the first cylindrical lens 130 and the second cylindrical lens 140 to rotate in the axial direction according to the target value, so that the cross angle between the axial directions of the first cylindrical lens 130 and the second cylindrical lens 140 matches the target value.
[0018] The first cylindrical lens 130 and the second cylindrical lens 140 are used to sequentially transmit the adjusted annular beam through the first cylindrical lens 130 and the second cylindrical lens 140 to the user's eye 200.
[0019] In some embodiments, the transmission assembly 160 may drive one of the first cylindrical lens 130 and the second cylindrical lens 140 to rotate in the axial direction according to the target value, so that the cross angle between the axial directions of the first cylindrical lens 130 and the second cylindrical lens 140 matches the target value.
[0020] In other embodiments, the transmission assembly 160 may drive the first cylindrical lens 130 and the second cylindrical lens 140 to rotate in the axial direction according to the target value, so that the cross angle between the axial directions of the first cylindrical lens 130 and the second cylindrical lens 140 matches the target value.
[0021] In some embodiments, the controller 150 may obtain the target value of the intersection angle between the first cylindrical lens 130 and the second cylindrical lens 140 from a pre-saved correspondence between the astigmatism parameters of the user's eye 200 and the intersection angle between the first cylindrical lens 130 and the second cylindrical lens 140.
[0022] In some embodiments, the astigmatism parameters in this embodiment may include astigmatism degree and astigmatism axis, which are not specifically limited in this embodiment.
[0023] In some embodiments, the astigmatism parameters may be provided to the optical system 100 by the corresponding user. This embodiment does not specifically limit the way in which the optical system 100 obtains the astigmatism parameters.
[0024] In some embodiments, the first cylindrical lens 130 may be disposed between the compensation adjustment assembly 120 and the second cylindrical lens 140.
[0025] It should be noted that, Figure 1 The example does not show the cross angle between the axial directions of the first cylindrical lens 130 and the second cylindrical lens 140 matching the target value.
[0026] As an example, an example diagram showing the intersection angle α between the axial directions of the first cylindrical lens 130 and the second cylindrical lens 140 is shown. Figure 2 As shown, it should be noted that, Figure 2 The example also illustrates the axial orientation of the first cylindrical lens 130 and the second cylindrical lens 140.
[0027] In some embodiments, such as Figure 1 As shown, the optical system 100 of this embodiment may further include: The target surface 170 is disposed between the annular beam generating component 110 and the compensation adjustment component 120, and is used to modulate the annular beam to obtain an annular beam carrying the target pattern.
[0028] In some embodiments, the target surface 170 may be a transparent optical element or a semi-transparent optical element. As an example, the target surface 170 may be transparent glass or semi-transparent glass with a target pattern, but this embodiment does not specifically limit this.
[0029] The target pattern is preset according to requirements, and this embodiment does not specifically limit the target pattern.
[0030] In some embodiments, the compensation adjustment component 120 may include a compensation eyepiece group (not shown in the figure), wherein the spacing between at least two eyepieces in the compensation eyepiece group is adjustable.
[0031] It should be noted that this embodiment uses a compensating eyepiece group consisting of two eyepieces as an example for illustrative description.
[0032] In some embodiments, the compensation adjustment component 120 may be a zoom eyepiece or other lens that can clearly image the ring beam onto the retina of the user's eye 200, in addition to being a compensation eyepiece group. This embodiment does not specifically limit this.
[0033] The optical system provided in this embodiment determines a target value for the intersection angle between a first cylindrical lens and a second cylindrical lens based on the astigmatism parameters of the user's eye. According to the target value, the controller rotates at least one of the first and second cylindrical lenses along its axial direction to match the intersection angle between their axial directions with the target value. The annular beam generated by the annular beam generation component is then sequentially transmitted through the compensation and adjustment component, the first cylindrical lens, and the second cylindrical lens to the user's eye. Thus, by adjusting the intersection angle between the first and second cylindrical lenses in conjunction with the user's astigmatism parameters, the intersection angle in the optical system is adapted to the user's astigmatism parameters. This allows the optical system to meet the needs of users with different astigmatism parameters, improving its adaptability.
[0034] In some embodiments, Figure 1 Based on the embodiments shown, such as Figure 3 As shown, the annular beam generating assembly 110 may include: a light source 111; The first collimation group 112 is used to collimate the light beam emitted by the light source; The light-blocking aperture 113 is used to block the light beam emitted by the first collimating group to form a circular light beam; A reflective aperture 114, wherein the reflective aperture 114 has a first aperture, the reflective aperture 114 is used to reflect a circular beam to form an annular beam, wherein the beam direction of the annular beam is parallel to and opposite to the line of sight of the user's eye 200.
[0035] In some embodiments, the first collimation group 112 in this embodiment may be a collimating lens, or other components capable of collimating the light beam; this embodiment does not specifically limit this.
[0036] It should be noted that the light source 111 can be any type of light source, such as a laser light source or a red LED with a wavelength of 650nm. This embodiment does not specifically limit the light source in this regard.
[0037] In some embodiments, the light-shielding aperture 113 in this embodiment includes: a second aperture and an annular light-shielding plate, wherein the annular light-shielding plate 113 is used to shield the light beam emitted by the first collimation group.
[0038] In some embodiments, the size of the second aperture of the light-shielding aperture 113 in this embodiment can be adjusted or fixed; this embodiment does not specifically limit this.
[0039] In some embodiments, the second aperture is larger than the first aperture.
[0040] Among them, an example diagram of the light-blocking aperture is shown below. Figure 4 As shown.
[0041] In some embodiments, the reflective aperture in this embodiment may include a first aperture and an annular reflective sheet. An example diagram of the reflective aperture is shown below. Figure 5 As shown.
[0042] In some embodiments, in order to provide gaze guidance to the user's eyes 200, such as Figure 3 As shown, the optical system 100 may further include: A gaze lamp 180, wherein the light emitted by the gaze lamp 180 passes through the first aperture of the reflective aperture 114 and is projected onto the user's eye 200.
[0043] In some embodiments, in order to make the polarization characteristics of the light spot on the retina more effectively improve the vision of the user's eye 200, the optical system 100 may further include a polarization component (not shown in the figure).
[0044] In some embodiments, a polarization component is disposed between the light source 111 and the first collimation group 112 for polarizing the light beam emitted by the light source 111.
[0045] In some embodiments, the polarization component may include a polarizer and a waveplate. Correspondingly, the beam emitted by the light source 111 can be polarized by the polarizer and the waveplate to switch the beam from a first polarization state to a second polarization state. The first polarization state and the second polarization state are different. For example, the first polarization state may be a non-polarized state and the second polarization state may be a linear polarization state. Alternatively, the first polarization state may be a linearly polarized state and the second polarization state may be an elliptical polarization state.
[0046] In other embodiments, a polarization component is disposed between the second cylindrical lens 140 and the user's eye 200, and the polarization component is used to polarize the light beam emitted from the second cylindrical lens 140.
[0047] In some embodiments, the polarization component may include a polarizer and a waveplate. Correspondingly, the beam emitted from the second cylindrical lens 140 can be polarized by the polarizer and the waveplate to switch the beam from a first polarization state to a second polarization state. The first polarization state and the second polarization state are different. For example, the first polarization state may be a non-polarized state and the second polarization state may be a linear polarization state. Alternatively, the first polarization state may be a linearly polarized state and the second polarization state may be an elliptical polarization state.
[0048] In this embodiment, the polarizer may include, but is not limited to, a linear polarizer, a circular polarizer, an elliptical polarizer, etc.
[0049] In this embodiment, the waveplate may include, but is not limited to, a quarter waveplate, a half waveplate, etc.
[0050] As an example, when the light source 111 is a non-linearly polarized light source, in order to make the light spot projected onto the user's eye 200 linearly polarized, thereby more effectively improving the user's vision, the polarization component in this embodiment may include a linear polarizer and a quarter-wave plate to polarize the second annular beam and project the polarized second annular beam onto the retina of the user's eye 200, thereby making the light spot projected onto the user's eye 200 linearly polarized, which helps to more effectively improve the user's vision.
[0051] It should be noted that, Figure 3 The controller and transmission components are not shown in the example.
[0052] To facilitate a clear understanding of this disclosure, the following will be combined with... Figure 3 The process by which the optical system of this embodiment projects a light beam onto the user's eye 200 is described exemplarily: In some embodiments, the light beam emitted by the light source 111 passes through the first collimation group 112 to form a parallel and uniform broad beam. Correspondingly, the light beam emitted by the first collimation group 112 passes through the light-shielding aperture 113 to form a circular beam, wherein the diameter of the circular beam is the same as the diameter of the second aperture of the light-shielding aperture 113. Correspondingly, the circular beam passes through the reflection aperture 114 to form an annular beam, wherein the beam direction of the annular beam is parallel to and opposite to the line of sight of the user's eye 200. Correspondingly, a gaze lamp 180 is placed to the left of the reflection aperture 114. The gaze lamp 180 emits a micro-light beam that enters the optical system through the first aperture of the reflection aperture 114 to guide the user's eye 200 to gaze, ensuring the consistency of the line of sight.
[0053] An example diagram of a circular beam is shown below. Figure 6 As shown, where, Figure 6 D1, as shown, represents the diameter of the circular beam, which is equal to the diameter of the second aperture of the light-blocking aperture 113.
[0054] Among them, an example diagram of a ring beam with a fixation point is shown, such as Figure 7 As shown, where, Figure 7 In this context, D1 represents the outer diameter of the ring beam, and D2 represents the inner diameter of the ring beam. The ratio of the outer diameter to the inner diameter of the ring beam is K = D1 / D2. Figure 7 The small black rectangle in the middle represents the gaze point, which is formed based on the light emitted by the gaze lamp.
[0055] It can be understood that the size of the second aperture of the light-blocking aperture 113 is used to limit the diameter of the circular beam.
[0056] The annular reflector of the reflective aperture 114 is used to reflect light. Light passing through the first aperture of the reflective aperture 114 is not reflected and does not enter the optical system.
[0057] The size of the first aperture is used to limit the inner diameter of the ring beam.
[0058] Correspondingly, the target surface 170 modulates the annular beam to obtain an annular beam carrying the target pattern. Then, the compensation adjustment component 120 compensates and adjusts the annular beam emitted from the target surface 170 so that the adjusted annular beam is imaged on the retina of the user's eye 200. The controller is used to determine the target value of the intersection angle between the first cylindrical lens 130 and the second cylindrical lens 140 according to the astigmatism parameters of the user's eye 200. The transmission component is used to rotate at least one of the first cylindrical lens 130 and the second cylindrical lens 140 in the axial direction according to the target value so that the intersection angle between the axial directions of the first cylindrical lens 130 and the second cylindrical lens 140 matches the target value. Correspondingly, the first cylindrical lens 130 and the second cylindrical lens 140 are used to sequentially transmit the adjusted annular beam through the first cylindrical lens 130 and the second cylindrical lens 140 to the user's eye 200.
[0059] It can be understood that in the optical system, the controller can first drive the axial direction of at least one of the first cylindrical lens 130 and the second cylindrical lens 140 to rotate through the transmission component, so that the cross angle between the axial directions of the first cylindrical lens 130 and the second cylindrical lens 140 matches the target value. Correspondingly, after the controller determines that the cross angle between the axial directions of the first cylindrical lens 130 and the second cylindrical lens 140 matches the target value, it controls the annular beam generating component 110 to form an annular beam.
[0060] To implement the above embodiments, this disclosure also proposes an electronic device.
[0061] Figure 8 This is a schematic diagram of the structure of an electronic device according to an embodiment of the present disclosure.
[0062] like Figure 8 As shown, the electronic device 10 may include: an optical system 100 according to a first aspect of this disclosure.
[0063] It should be noted that the foregoing explanation of the embodiment of the optical system 100 also applies to the electronic device of this embodiment, and this embodiment does not specifically limit it in this regard.
[0064] According to an embodiment of the electronic device disclosed herein, the controller determines a target value for the intersection angle between the first and second cylindrical lenses based on the astigmatism parameters of the user's eye. Based on the target value, the controller rotates at least one of the first and second cylindrical lenses along its axial direction to match the intersection angle between their axial directions with the target value. The annular beam generated by the annular beam generating component is then sequentially transmitted through the compensation and adjustment component, the first cylindrical lens, and the second cylindrical lens to the user's eye. Thus, by combining the astigmatism parameters of the user's eye with the adjustment of the intersection angle between the first and second cylindrical lenses, the intersection angle in the optical system is adapted to the astigmatism parameters of the user's eye. This allows the optical system to meet the needs of users with different astigmatism parameters, improving the adaptability of the optical system.
