Wearable optical devices with virtual reality (VR) functions provide an immersive video or audio-visual experience. With the improvement of hardware, they have matured, and in recent years, they have become the choice for many users to play games or watch videos.

Generally speaking, wearable optical devices can be divided into glasses-wearing and naked-sighting applications in terms of use types, and the reserved space for glasses is also considered in product design. Even so, if the user wears the glasses, the wearable optical device may press the glasses to cause discomfort to the user, or even damage the glasses. If the user can choose not to wear glasses and directly use the wearable optical device, the immersion will be reduced due to the extra space reserved for glasses, and the short-sighted person may not be able to see the image clearly or cause halo due to the problem of focal length. Dizziness or discomfort, but will make the user more resistant. In addition, each user's interpupillary distance is different. Wearing an improper interpupillary distance product will result in a poor experience or even no sense of immersion at all. Therefore, how to effectively respond to differences among users and support the adjustment of myopia and interpupillary distance at the same time has become an important issue for wearable optical devices.

Some typical embodiments embodying the features and advantages of the present case will be described in detail in the description of the latter paragraph. It should be understood that this case can have various changes in different aspects, all of which do not depart from the scope of this case, and the descriptions and diagrams therein are essentially for illustrative purposes rather than limiting the present case.

Please refer to Figure 1, Figure 2, Figure 3 and Figure 4, wherein Figure 1 is a perspective view showing the structure of the wearable optical device according to an embodiment of the present application, and Figure 2 is a diagram showing the wearable optical device according to an embodiment of the present application. Figure 3 is a schematic diagram showing the structure of the optical module of the wearable optical device according to an embodiment of the present application, and Figure 4 is an enlarged schematic diagram showing the partial structure of the area A shown in Figure 3. As shown in FIGS. 1 to 4, a wearable optical device 1 according to a preferred embodiment of the present application includes at least one optical module 2, wherein each optical module 2 includes a bracket 21, a lens barrel 22, and at least one latch 23 and lens 24. The lens barrel 22 is sleeved on the bracket 21 , and the lens barrel 22 has at least one oblique groove 221 . The plug pins 23 are fixed on the bracket 21 , and the number of the plug pins 23 is equal to the number of the oblique grooves 221 , and each plug pin 23 is correspondingly disposed in an oblique groove 221 and is limited by the oblique groove 221 . For example, if the lens barrel 22 has a total of three oblique grooves 221 along the circumference, the optical module 2 includes three pins 23, and the three pins 23 are respectively disposed in the three oblique grooves 221 and Each is limited by the corresponding oblique groove 221 , but the number of the plug 23 and the oblique groove 221 is not limited by this. The lens 24 is disposed on the lens barrel 22 . When the lens barrel 22 rotates, the latch 23 moves relatively along the oblique groove 221 , so that the lens 24 is driven by the lens barrel 22 , thereby changing the distance between the lens 24 and the bracket 21 . Therefore, when the user uses the wearable optical device 1 of the present application, the distance between the lens 24 and the bracket 21 can be changed only by rotating the lens barrel 22 , so as to realize myopia adjustment for adjusting the imaging position.

Similarly, in this case, because the latch 23 is restricted by the oblique groove 221, the lens barrel 22 can only be rotated in a clockwise direction. If the lens barrel 22 rotates in a clockwise direction, the latch 23 will rotate along the oblique groove 221. Relatively sliding down, the lens barrel will move upward until the pin 23 is located at the lower end of the inclined groove 221 away from the lens 24 (as shown in Figure 5).
