VOY's VR or MR lens insert is the world's first tunable lens for VR or MR devices. This insert allows myopic users to see VR or MR headset images clearly without wearing prescription glasses. The tunable range is from 0D to -6D, which covers the majority of myopic users. The product contains dioptor marks for precise tuning and is attached with a unique magnetic clip-on mechanism. The tunable lens insert cover is currently compatible with many popular headsets in the market including Meta Oculus Quest and others.
