Synopsis and Key Points:

Main Digest

The glasses have a sensor in the middle of the frame that uses sonar technology to inform the user if there are upcoming obstacles with a subtle vibration near the right temple. They also feature an adjustable range that can be customized to personal specifications.

Sonar Glasses allow the user to change the detection range between 3, 6, and 9 feet, hence providing the ability to use the glasses indoors and outdoors, as well as accommodating slow and fast walkers. This enhanced awareness facilitates the user’s movement and increases their autonomy in daily activities.

Lenses are available in clear, dark, photosensitive, and prescription.

All glasses come with two rechargeable batteries, a battery charger and ear locks.

There is also a one-year warranty for all glasses so they can be returned for a full refund if they do not deliver complete satisfaction.
