Abstract: According to an embodiment, a wearable electronic device may include a camera, a display, a lens assembly configured to focus or guide light beams representing visual information output from the display, the lens assembly including a first lens configured to adjust a refractive index by receiving an electrical signal, at least one processor and memory storing instructions. According to an embodiment, the instructions, when executed by the at least one processor, may cause the wearable electronic device to control the display to output the light beams representing the visual information through the lens assembly. According to an embodiment, the instructions, when executed by the at least one processor, may cause the wearable electronic device to adjust a refractive index of a first area of the first lens corresponding to a first distance from an edge of the first lens to reduce blur of a first object displayed based on the first light beams passing through the first area of the first lens corresponding to the first distance from the edge of the first lens. According to an embodiment, the instructions, when executed by the at least one processor, may cause the wearable electronic device to adjust the refractive index of the second area of the first lens to a second value corresponding to a second distance, which is longer than the first distance, from the edge of the first lens. Various other embodiments may be possible.
