PV Glasses are made by Carl ZEISS, AG and powered by the new ZEISS cinemizer OLED technology. They incorporate the most advanced OLED (Organic Light Emitting Diode) display technology and the world's most premium optics. ZEISS produces the cinemizer OLED for specialty applications around the world and PV Glasses are the first to bring this quality product to the Adult Entertainment market.
When PV Glasses is in use and the battery status LED is green, it is possible that the charge level is just above orange status. If a USB plug is inserted for charging, the battery status LED flashes red. This informs the user to charge the battery longer – which is also good for battery life.
