[0002] Head-mounted devices are products that utilize a combination of technologies such as simulation technology, computer graphics, human-computer interface technology, multimedia technology, sensor technology, and network technology. They are a new means of human-computer interaction created with the help of computers and the latest sensor technology. At present, there are a large number of people with myopia, so head-mounted devices must take into account the user experience of myopic people; head-mounted devices on the current market generally use the following two methods to be compatible with myopic users: one of which is that existing head-mounted devices can be worn directly on the user's head, that is, when using head-mounted devices, the user does not need to take off the glasses they wear, and the face-mounted part of the head-mounted device is directly covered on the outside of the user's glasses, which is conducive to improving the user experience; however, since the user wears both the glasses and the head-mounted device at the same time, the user's eyes are at a greater distance from the screen of the head-mounted device, which reduces the range of the screen that the user's eyes can see. The other is that the optical module of the existing head-mounted device has a function of adjusting the diopter, and the diopter is adjusted by a dial on the lens barrel of the head-mounted device; when in use, the user needs to adjust the two lens barrels of the head-mounted device to appropriate degrees before wearing the head-mounted device; however, in actual use, the user is often not very clear about the diopter of his or her eyes, so when using the head-mounted device, the user needs to wear or take off the head-mounted device many times to adjust the diopter of the lens barrel of the head-mounted device, which is inconvenient to use.
