Nuance Audio is a line of assistive devices developed by EssilorLuxottica, combining corrective eyewear with hearing enhancement technology. First announced in 2023 following EssilorLuxottica's acquisition of audiology company Nuance Hearing, the product received FDA clearance as a Class II medical device in 2025.

The integration of hearing assistance into eyewear reflects broader trends in wearable technology, particularly devices addressing age-related sensory impairments. Similar attempts include Bose's SoundControl hearing aids (2021) and Google's collaboration with hearing aid manufacturers on Android compatibility.

EssilorLuxottica acquired Nuance Hearing in July 2023, incorporating its audio processing patents into existing optical product lines. Clinical trials for the hybrid device began in 2024, focusing on compliance with medical device regulations in multiple jurisdictions.

• as of 2025, the device holds:
  • FDA Class II clearance under 21 CFR 874.3300
  • CE Mark certification under EU MDR 2017/745

The system integrates directional microphones into eyewear temples, using adaptive algorithms to amplify frequencies between 500–6000 Hz. Key components include:

• Photochromic lenses adjusting to light conditions
• Mobile app for audio profile customization
• Rechargeable lithium-ion battery with 14-hour runtime

A 2025 study in the Journal of Auditory Engineering noted technical limitations in microphone placement compared to traditional behind-the-ear hearing aids, particularly in environments with 65+ dB background noise.

Initial media coverage focused on the product's design approach to reduce perceived stigma associated with hearing aids. Technology analysts highlighted:

• Integration challenges between optical and audiological components
• Retail pricing 30-40% higher than conventional hearing aids
• Limited compatibility with severe hearing loss (above 70 dB HL)

Consumer organizations like the Hearing Loss Association of America raised concerns about insurance coverage, as most U.S. providers classify the device as elective rather than essential medical equipment.
