Read all of these safety warnings before using Glass Enterprise Edition 2 (“Glass”) or any of its accessories. Your failure to follow these safety warnings could cause serious personal injury or property damage.
Using Glass while performing certain activities can be distracting and create a dangerous situation for you or others. Do not perform tasks on Glass that would prevent you from concentrating on the activity at hand or from paying attention to your surroundings.
Heat and prolonged heat exposure to user
Electronics produce heat so some heat from Glass is normal. However, if as a result of heat, Glass becomes uncomfortable to wear or you notice redness or irritation in the area where Glass contacts your skin, remove and power off Glass and wait for the device to return to a comfortable temperature before resuming use. If the temperature of the device remains elevated or repeatedly heats to an uncomfortable level, stop using Glass and contact customer support. If you continue to experience skin redness or irritation, stop using Glass and consult with your physician. Prolonged heat exposure may cause burning, blistering, or other damage to your skin. Glass may become warm when in use or while plugged into a power source so follow the charging instructions below. Take special care if you have a condition that prevents you from detecting heat against your body and do not sleep while wearing Glass.
Glass contains a lithium-ion battery. Puncturing, incinerating, deforming, bending, heating, modifying, attempting to insert foreign objects, shorting the contacts, trying to disassemble, or exposing the batteries to water or extreme temperatures (below 5°C (41°F) or above 60°C (140°F) for storage or use and below 0°C (32°F) or above 45°C (113°F) while charging), may damage the battery and could cause explosion, fire and injury or property damage. Do not attempt to replace the Glass battery. Batteries must be properly recycled or disposed of in accordance with applicable law.
Glass is not designed for children under age 14. Children above 14 and under 18 years must only use Glass with parental or legal guardian’s consent and supervision. To avoid possible breakage, injury from misuse, and other possible harm to the user, do not let children under 14 use or handle Glass.
Potential safety conditions
Do not use Glass or any accessories if they become damaged. Avoid dropping Glass on the ground or other hard surfaces. Prior to use, always inspect Glass for signs of damage, such as fissures in the device body, exposed electrical components, cracks, bubbling, or chipping within the Glass display. Damage to the battery and electrical circuitry could cause the device to malfunction, creating a risk of excessive heat emission, explosion, electric shock, or fire.
Glass is water resistant but not waterproof. The device has a water protection rating of IPX3 under IEC standard 60529. Water resistance may be compromised due to normal wear and tear or damage to the device. The Glass USB-C charging cable is not water resistant. Do not charge the device when wet.
Glass may become warm when used or while plugged into a power source so be sure the power adapter and Glass are well ventilated when in use or charging. Using a damaged cable or power adapter or charging when moisture is present can cause fire, electric shock, injury, or damage to Glass or other property. When charging Glass, make sure the power adapter is plugged into a socket near Glass and is easily accessible. Avoid charging the device in direct sunlight. Only charge Glass with the included cable, or compatible charging accessories. Failure to use compatible charging accessories can cause fire, electric shock, injury or damage to Glass and the accessories. When disconnecting the power adapter from a power outlet, pull on the adapter, never on the cable. Do not twist or pinch the USB cable, and do not force a connector into a port.
Use with safety eyewear and prescription frames
Glass may be paired with safety eyewear or prescription frames and/or prescription lenses that have been designed and approved by the seller for use with Glass. Users who need eye protection when using Glass should make sure they use eye protection that meets applicable safety standards. Users may require time to become accustomed to using Glass with prescription frames or prescription lenses.
Prior Glass edition frames
Frames for Glass Edition 1 (“Edition 1”) may fit Glass Edition 2, but they have not been tested by Google for compatibility. Edition 1 frames are only tested and approved for use with Gen 1 devices. They are not tested or approved for use with Glass Edition 2.
Habituation to Glass
New Glass users should increase wear time slowly to habituate to the optical display. The habituation period to Glass when paired with prescription frames and/or prescription lenses may take a bit longer, usually between 1 and 2 weeks. Expect a longer habituation period for higher prescriptions and if you wear progressive lenses with Glass.
If you feel eye strain or get a headache while wearing Glass, take a break from using Glass. To avoid discomfort, take regular breaks and use Glass in well-lit conditions without excessive sunshine. If discomfort persists, stop using Glass and consult with your physician. Recurring symptoms could be a sign of a more serious underlying medical condition.
Situate Glass properly
When using Glass, the Glass display should be located just above the line of sight of your right eye. If positioned improperly, Glass may obstruct your vision and lead to an accident. If the Glass display sits too low, you may tend to tilt your head up when viewing straight ahead. This can cause neck strain as well as blurry vision if you are wearing Glass with prescription lenses.
Protecting Glass when adjusting eyewear
Before making any eyewear adjustments, detach Glass from the eyewear. Eyewear adjustments may involve bending, the use of external heat sources, or other manipulations that, if performed with Glass attached, could damage Glass and create a risk of explosion or fire.
Do not use in explosive atmosphere or flammable environment
Glass does not comply with IEC 60079 (Explosive Atmosphere Standards). Do not use or charge Glass in an explosive atmosphere, any area where a spark could ignite a fire or cause an explosion, or while handling a flammable substance. Always look for and follow posted safety instructions.
Do not use where fail-safe performance is required
Glass is not designed, manufactured, or intended for use in hazardous environments requiring fail-safe performance in which the failure of Glass could lead directly to death, personal injury, or severe physical or environmental damage.
Obey applicable laws and restrictions
Do not use Glass in a place or manner not permitted. Many jurisdictions have passed laws limiting the use of mobile devices while driving a motor vehicle. You should understand and comply with these laws. In addition, some venues restrict the use of devices with recording capabilities. Hospitals and other venues may restrict the use of WiFi and Bluetooth-enabled devices. You may also be in certain places where those around you don't feel comfortable being photographed or captured on video. Always consider your surroundings—just like you would with a cell phone.
Personal medical devices
Glass and its power cable contain magnets. When in operation, Glass also emits electromagnetic energy. All of the above may interfere with the operation of pacemakers and other implantable medical devices. If you have an implanted medical device, contact your medical device manufacturer and/or physician to make sure it’s okay to use Glass. In addition, to minimize the likelihood of potential interference, keep Glass and its accessories away from your implanted medical device (for example, don’t carry Glass in your chest pocket if you have a pacemaker).
Glass is not a medical device
Glass is not registered by the manufacturer as a medical device with any regulatory authority and is not designed or intended for use as a medical device in the diagnosis, treatment, cure, mitigation or prevention of disease or other conditions or to affect the structure or function of the body. Glass, if paired with prescription frames and/or prescription lenses, may be regulated as a medical device in certain jurisdictions. Contact the seller of prescription frames and/or prescription lenses for Glass for information on the listings with the appropriate regulatory authorities in the applicable jurisdictions.
