Abstract

An optical lens module for providing augmented reality content includes an optical lens, in which reflection members provide image light as a pupil of a user's eye, a connection member coupled with the optical lens, and a display providing image light to the reflection members. The display is disposed on a seating structure of the connection member. A first coupling structure extending laterally is formed on one side of the optical lens. Second coupling structures are formed on one side of the connection member in the lateral direction. A gap is formed between the second coupling structures. In a state in which the connection member and the optical lens are coupled based on the concave structure and the protruding structures being coupled to each other, image light output from the display is provided in the direction of the optical lens through the gap between the protruding structures.
