With the black Rochester Optical Solitaire Ace 2.0 for Epson BT-300 Moverio, you can transform your AR glasses into a full VR experience. The Solitaire Ace is designed to attach to a pair of Epson BT-300 Moverio AR glasses, blocking out your surroundings for a more immersive VR experience. Simply attach the included blackout shield to make the switch. Without the blackout shield, the Solitaire Ace 2.0's category 4 polarized sun lenses block out most light, with only 4-5% transmittance for enhanced contrast.
