SAMONIC 3D VR Goggles 【Aspherical Optical Lenses】 This product uses aspherical optical lenses with blue light cut and electromagnetic radiation protection functions, reducing eye strain, preventing glare, and alleviating eye fatigue. 【Pupil/Focal Distance Adjustment】 Since everyone's interpupillary distance and focal distance are different, you can freely adjust the focus on the goggles to set it to the most comfortable viewing state. Even those with nearsightedness can experience VR with their naked eyes through adjustment. Japanese instruction manual included. I received this from a friend, but I never used it, so I'm putting it up for sale. It's a used item.
