HEAD MOUNTED DISPLAY APPARATUS TO ADD VISION CORRECTION LENSES

The present invention relates to a head-wearable display device, and more particularly, to a head-wearable display device to which a vision correction lens can be added.

Various wearable devices are being developed in accordance with the trend of weight reduction and miniaturization of digital devices. A head mounted display, which is a type of wearable device, refers to various devices that a user can wear on the head to receive multimedia contents. Here, the head mounted display (HMD) is worn on the user's body and provides images to the user in various environments as the user moves. Such a head mounted display (HMD) is divided into a see-through type and a see-closed type, and the transparent type is mainly used for Augmented Reality (AR), and the closed type is mainly used for virtual reality (Virtual Reality). Reality, VR).
