Nuance Audio Glasses are not a mere “sound amplifier”, but a proper medical device. They are eyewear frames embedded with groundbreaking technology which seamlessly integrate an air conduction hearing aid (over-the-counter “OTC”, in the United States) intended to amplify sound for adult users (18yrs and older) with a perceived mild to moderate hearing impairment. Nuance Audio Glasses may, if necessary, be used in association with prescription lenses for those adults who also require correction of visual defects. Nuance Audio Glasses can be worn all day and can be easily configured via the App to adapt to any situation, from business meetings to family time.
