     DETAILED DESCRIPTION 
     Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same reference numeral in different drawings represents the same or similar elements unless otherwise specified. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the disclosure as recited in the appended claims. 
     Terms used in the disclosure are for the purpose of describing exemplary embodiments only, and are not intended to limit the disclosure. For example, although the terms “first,” “second,” etc. may be used in the disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the disclosure, first information may also be referred to as second information and, similarly, second information may also be referred to as first information. 
       FIG. 1  is a schematic diagram illustrating phototherapy glasses  100  according to some embodiments of the disclosure. As shown in  FIG. 1 , the phototherapy glasses  100  may include a front frame  1 , a first temple  2 , and a second temple  3 . The first temple  2  and the second temple  3  are hinged to a first side and a second side of the front frame  1 , respectively. Therefore, the first temple  2  and the second temple  3  can be folded in a direction close to the front frame  1 , and the phototherapy glasses  100  are switched to a folded state and are convenient to carry. Both the first temple  2  and the second temple  3  can be unfolded in a direction away from the front frame  1 , and the phototherapy glasses  100  are switched to an unfolded state. Therefore, the phototherapy glasses  100  may be worn on the face of a user as shown in  FIG. 2 , and phototherapy light may be emitted into the eyes of the user to achieve the phototherapy effect. 
     Further, the phototherapy glasses  100  may further include a light source component  4 , a lens  5 , and a reflecting layer  6 . The light source component  4  may be disposed on at least one of the first temple  2  or the second temple  3 . The lens  5  may be disposed on the front frame  1 . The reflecting layer  6  may be formed on the lens  5 . The reflecting layer  6  may be configured to reflect light from the light source component  4 , so that the light from the light source component  4  can be reflected to the eyes of the user to achieve the phototherapy effect. The phototherapy glasses  100  may further include a color changing layer formed on the lens  5 . The color changing layer may change color according to the intensity of irradiated ultraviolet light. For example, when the ultraviolet light is strong, the color of the color changing layer is darkened, and light entering the eyes of the user is weakened. When the ultraviolet light is weak, the color of the color changing layer is lighter, which is beneficial to light transmission and makes the eyes of the user more adaptable to current environmental conditions. 
     The technical solutions provided by the embodiments of the disclosure may include the following beneficial effects. 
     In the above embodiments, the phototherapy glasses  100  can be stored and worn through the folding and unfolding of the first temple  2  and the second temple  3  relative to the front frame  1 . The structure is simplified as compared to the phototherapy glasses in the related art. Further, the light source component  4  is disposed on the first temple  2  or the second temple  3  and cooperates with the reflection effect of the reflecting layer  6  to simplify the appearance structure of the phototherapy glasses while achieving the phototherapy effect. 
     In some embodiments, the reflecting layer  6  may be disposed on a side of the lens  5  facing the eyes of the user, thereby avoiding the light from the light source component  4  from being weakened or refracted during the process of light transmission through the lens, which is beneficial to ensure the phototherapy effect. Further, the reflecting layer  6  may allow light of a fixed frequency to be reflected, and light of a frequency other than the fixed frequency may pass through the reflecting layer  6 , so that the user can see the outside world with the phototherapy glasses while ensuring the phototherapy effect. 
     In an embodiment, as shown in  FIG. 3 , the light source component  4  may include a light source  41  and a plano-convex lens  42 . The plano-convex lens  42  includes a light incident surface  421  and a light exit surface  422 . Light emitted by the light source  41  may enter the light incident surface  421  of the plano-convex lens  42  and may exit from the light exit surface  422  perpendicularly. Based on this, the scattered light emitted by the light source  41  may be converted to mutually parallel light, and further into linear light that can be emitted to the reflecting layer  6 , thereby reducing the amount of light loss. 
     In this embodiment, the light source  41  may be disposed at a focal point of the lens  5 , and an angle formed by parallel light exiting from the plano-convex lens  42  and the lens  5  may be between 25° and 55°. Therefore, the light from the light source  41  may be emitted to the reflecting layer  6  obliquely. By adjusting the position of the reflecting layer  6  and an incident angle of the light, it is beneficial to make the light from the light source enter the eyes of the user perpendicularly, thereby improving the visual effect and the phototherapy effect. The light source  41  may include an LED light source, such as blue LED light of 465 nm, blue light with the illumination intensity of 1001 ux, green light with the illumination intensity of 3501 ux or white light with the illumination intensity of 1000-50001 ux, which may be specifically designed according to therapy requirements and will not be limited in the disclosure. 
     In some embodiments, the reflecting layer  6  may include a non-metallic dielectric film layer, which is beneficial to realize the connection between the reflecting layer  6  and the lens  5 . For example, the reflecting layer  6  may include a dichroic coating or a dielectric coating. When the reflecting layer  6  is a dielectric coating, for example, a film layer may include 25-30 layers, and the thickness of the reflecting layer  6  is, for example, 2 um±1 um. The reflecting layer may be specifically designed as required and will not be limited in the disclosure. 
     In some embodiments of the disclosure, as shown in  FIG. 1 , the front frame  1  may include a first support frame  11 , a second support frame  12 , and a connecting member  13  connecting the first support frame  11  and the second support frame  12 . The first support frame  11  may be hinged to the first temple  2 , and the second support frame  12  may be hinged to the second temple  3 . Moreover, the first support frame  11  and the second support frame  12  may include openings, respectively, so that the lens  5  may be fitted into the openings and fixed. For example, the lens  5  may include a first lens disposed in the first support frame  11  and a second lens disposed in the second support frame  12 . 
     In some embodiments, in order to equalize the light intensity felt by the two eyes of the user, the first lens and the second lens may each be provided with the reflecting layer  6 , and the first temple  2  and the second temple  3  may each be provided with the light source component  4 . The switching states of the light source components  4  disposed on the first temple  2  and the second temple  3  may be synchronized to equalize light reflected into different eyes of the user. 
     In some embodiments, the light source  41  may include a first light source located on the first temple  2  and a second light source located on the second temple  3 . Further, as shown in  FIG. 4 , the phototherapy glasses  100  may further include a light source control circuit  7  and a battery  8 . In one embodiment, the battery  8  may be located in the first temple  2  or the second temple  3 , a first end of the light source control circuit  7  may be electrically connected to the battery  8 , and a second end of the light source control circuit  7  may be connected to the first light source and the second light source, so that the first light source and the second light source are powered by the battery  8 . In another embodiment, the battery  8  may include a first battery in the first temple  2  and a second battery in the second temple  3 . Similarly, the light source control circuit  7  may include a first circuit located in the first temple  2  and a second circuit located in the second temple  3 . The first circuit is connected to the first light source and the first battery, and the second circuit is connected to the second light source and the second battery, so that the first battery supplies power to the first light source, and the second battery supplies power to the second light source. 
     Further, as shown in  FIG. 4 , the phototherapy glasses  100  may further include a charging module  9 . The charging module  9  is electrically connected to the battery  8 , so that the battery  8  can be charged when the charging module  9  is connected to an external power source. The external power source may be an external power socket or a power bank or another discharge terminal. 
     In order to protect the phototherapy glasses  100  during non-therapy periods, the disclosure also provides a glasses case (not shown in the figure). The glasses case may cooperate with the phototherapy glasses  100  in each of the above embodiments. Furthermore, the glasses case may further include a charging component. The charging component may cooperate with the phototherapy glasses  100 , so that the phototherapy glasses  100  can be charged through the glasses case, and a situation of insufficient power when a user starts the phototherapy glasses  100  can be avoided. In an embodiment, the charging component may include a physical charging interface. The physical charging interface is electrically connected to the charging module  9  of the phototherapy glasses  100  for charging. The physical charging interface may include a USB-C type interface. In another embodiment, the charging component may also charge the phototherapy glasses by wireless charging. For example, the charging component includes an electromagnetic induction type wireless charging coil and forms a charging area inside the glasses case. When the phototherapy glasses  100  are placed in the glasses case and the charging module  9  of the phototherapy glasses  100  is aligned with the charging area in the glasses case, charging can be realized, and the use of a data cable is avoided, which is convenient and quick. Alternatively, the phototherapy glasses may also be wirelessly charged by being attached to the glasses case in a contact manner. 
     In one embodiment, the glasses case itself may also be charged in a wired or wireless manner, which is not limited here. 
     In one embodiment, the glasses case may further include an indicator light for displaying a charging state of the phototherapy glasses. The glasses case may also include a display screen for displaying the current power of the phototherapy glasses.
