Charging

Battery Life

• Envision consumes most of the battery when in use due to the need to have the camera active and light detection when using all features.
• Envision Glasses can be used for 4 to 6 hours per day in normal use conditions. Normal use means using a few Envision Glasses features once every hour or a couple of hours, not consecutively. If the glasses are used non-stop, the battery will drain faster.
• As batteries do not work in a linear fashion, some devices drain battery power easily from 100% to 80% and from 80% to 40% a little slower. If that happens with your Envision Glasses it is definitely normal behaviour.
• Even if the glasses are turned off or in Sleep Mode, it is normal for the battery to discharge, this behavior is similar to all electronic devices that use lithium batteries. The discharge will be more noticeable compared to other devices, as Envision Glasses hardware has a small module which, compared to the battery of a phone or other larger devices, will have a considerably shorter life.
• Lithium-ion batteries need to maintain a certain voltage to work properly. If the voltage drops, even if the battery still has charge left, the device may not be able to start until it receives enough charge to bring the voltage back up. This behaviour is often referred to as battery threshold lockout. This feature is designed to protect the battery and the device from damage and ensures safe and reliable operation.

Powering Envision Glasses after a long period of disuse

• If you haven't charged Envision Glasses for a couple of days/weeks, it may take longer to charge them. In this state, it's normal that Envision Glasses won't turn on when you press the Power Button. But don't worry. Grab a cup of coffee and return in a bit, and Envision Glasses should turn on normally. 

Take advantage of a fast charging adapter

• Inside the zippered pocket of the carrying case, you’ll find a power cable. This is a USB-A to USB-C cable, which allows you to charge your Envision Glasses by connecting it to any standard USB power adapter.
• The Envision Glasses support fast charging, and while the included cable is designed for standard charging, this setup works reliably with most USB power adapters. Charging times may vary depending on the adapter, and it’s completely normal when using the cable provided.
• If you’d like to charge your device more quickly, we recommend using a fast charging adapter along with a USB-C to USB-C cable that fully supports fast charging.

Recommended setup for fast charging

• A 30W or higher USB-C power adapter and USB-C to USB-C cable that supports power delivery or fast charge.
• When having charging problems, we recommend to please check the power outlets, the USB-C charging cable and the power adapter.
  
  Disclaimer: Connecting the Envision Glasses to a computer using the included cable will usually not charge the device. As well, the device will not be detected by most desktop or laptop computers.

Be prepared when leaving home

If you’re planning to spend a lot of time away from home, having a power bank can make a big difference—especially if you’re using your phone as a personal hotspot while wearing your Envision Glasses. Below are two power bank options to help you stay charged throughout the day:

High-Capacity Power Bank:

• Ideal for: Long days out, travel, or situations where you may not have regular access to a wall charger.
• Why it’s helpful: It can recharge your Envision Glasses multiple times, along with your phone or other devices, and is ideal for users who rely on personal hotspots or need extended use throughout the day.
• What to look for: A capacity of at least 20,000mAh, a USB-C port that supports power output, not just input and output specs of at least 1.5A at 5V for compatibility with fast charging.

Compact Power Bank:

• Ideal for: Short outings, quick top-ups during the day, or as a lightweight backup power source.
• Why it’s helpful: The Envision Glasses have a relatively small battery, so even a low-capacity power bank can recharge them once or twice, and it’s compact enough to carry in your pocket or glasses case.
• What to look for: A capacity of around 5,000mAh and a USB-C output port with at least 1.5A at 5V.

Charging Tip

Ensure that the power bank’s USB-C port supports output charging. Some compact power banks may have USB-C ports intended only for charging the power bank itself. While the included USB-A to USB-C cable works well for standard charging, using a USB-C to USB-C cable that supports fast charging, in combination with a compatible power bank, can provide quicker charging times for your Envision Glasses.

Having the right power bank and cable setup means more confidence and fewer interruptions when you’re on the go. Whether you choose a compact or high-capacity option, ensure compatibility with USB-C output and fast charge standards for the best experience.

Protecting

Your Envision Glasses are shipped with a protective case. We recommend that you always store your Envision Glasses in this hard case to ensure that they are accident-free.

External force, such as a blow or a fall, can damage the housing and the unit may no longer be water resistant as a result. It is recommended not to expose the glasses to rain, especially heavy rain or water, for a long period of time.

Cleaning

Envision Glasses are water-resistant with an IPX3 rating, which means they can handle light splashes and gentle cleaning. However, they should not be submerged in water or exposed to heavy moisture, as this may affect their performance over time.

How to Clean Your Glasses

• Always turn off and unplug your device before cleaning.

• Use a soft cloth dampened with a mild solution of natural detergent and water, or with a 70 to 80 percent isopropyl alcohol solution, to wipe all surfaces.

• Disinfectant wipes that are safe for human skin are also suitable.

• Dry the device using a clean, soft cloth or let it air dry naturally.

Important Tips

• Do not use bleach or any cleaner that contains bleach.

• Avoid spraying liquids directly on the device.

• Never insert sharp objects or use abrasive materials on any part of the glasses.

• Be extra gentle around the camera, touchpad, and USB-C port. Use a microfiber cloth or cotton swab to clean these areas if needed.

• Avoid getting moisture or cleaning products inside any openings.

Regular cleaning helps maintain hygiene and preserves the condition of your Envision Glasses.

Extend The Life Of Your Envision Glasses

To help ensure long-lasting performance, we recommend following these care guidelines based on the device’s technical specifications and durability rating.

1. Environmental Conditions

• Do not expose the device to heavy rain or submerge it in water. While the Envision Glasses have an IP53 rating, they are only resistant to light water spray.
• Keep the device away from excessive dust or sand, as this may compromise the limited dust ingress protection.
• Avoid contact with direct flames or surfaces that are highly heated, as the plastic components and internal hardware are sensitive to extreme temperatures.

For more information on the technical specifications of Envision Glasses, please see Technical Specifications

2. Handling and Storage

• Always store your Envision Glasses in the provided hard protective case when not in use to prevent accidental damage.
• Avoid dropping the device or subjecting it to physical shocks. Any external force may damage internal components and reduce water resistance.
• Do not twist, bend, or place weight on the device, especially when packing or carrying it in a bag.

3. Safe Usage

• Avoid using harsh disinfectants or exposing the glasses to corrosive environments.
• Clean your device regularly to prevent build-up that may block sensors or degrade performance.
• Do not press too firmly on the touchpad or buttons, as these are sensitive input areas.
• Refrain from using rough materials or scrubbing the surfaces, which may cause wear or damage.
