The Reloptix Quest 3 design is our thinnest profile yet. Our slim profile allows for even the thickest prescriptions to hide well. Also due to this thin of a frame some lens curvatures will bend the frame slightly causing a gap between your frame and base adapter in some areas. Not to worry, our insert has been designed with this in mind and won't break loose even with higher prescriptions. The frames feature rear posts that stick into the base adapter, preventing the frame from twisting while mounted. Four strong neodymium magnets coupled with a low profile front clip, keep the frame attached to the base and provide maximum FOV. -15 to +8 sphere up to -7 cylinder has been tested for functionality and durability during game play. Game on!
