Important Safety Information

Luna Glass is intended to support people with night blindness during everyday activities, by enhancing low-light scenes in real time. It provides a brighter image with improved color and contrast to help users better detect objects, edges, and obstacles. Luna Glass is not recommended for people with sensitivity to light. There are no limits to how often or how long the device can be used. For a full list of all safety warnings, please consult the product manual.

Please handle Luna Glass with care. As a first-generation early adopter device, it contains delicate optics and electronic components that require careful handling to prevent scratches or damage.

Please take some time to get comfortable using Luna Glass in a safe and familiar setting before relying on it in public or unknown environments.

  • If the battery leaks and fluid contacts your skin or eyes, rinse with plenty of water and seek medical attention immediately.
  • Stop using the device immediately if it becomes very hot, emits smoke or odor, swells, or leaks. Place it in a fire-safe area and contact support.

Personal discomfort

In some rare cases, using Luna Glass may cause personal discomfort. Possible side effect may include eye strain or fatigue, motion sickness, depth perception or spatial awareness error and nausea. 

  • Stop using Luna Glass if you experience redness, swelling, itching, or rash. Only resume when symptoms are gone. If symptoms persist, consult a healthcare professional.
  • Ensure the glasses fit properly and do not apply excessive pressure.
  • Keep contact surfaces clean and dry.

Additional safety guidance

Please keep the following in mind when using Luna Glass.

  • Luna Glass is not a substitute for a white cane, symbol cane, or guide dog. Use it together with other assistive tools when needed.
  • The device may reduce peripheral vision. Stay aware of your surroundings and turn your head to look around, not just your eyes.
  • Be extra careful when walking, using stairs, or stepping off curbs, as depth perception may be affected.
  • If you see heavy visual noise (static), visibility may be reduced. Only move when you can clearly perceive your surroundings. If there is too little light, use a flashlight to provide light for the device to amplify.
  • Do not move while using low-light mode.
  • Do not move during configuration.
  • The displayed image may not perfectly align with the real world at all distances, especially at close range. This can affect hand-eye coordination.
  • Do not use Luna Glass in rain or snow, and do not submerge it or use it underwater.

  • Camera stops working (no image);
  • Image freezes or turns green;
  • Device turns off unexpectedly;
