A thin electrochromic film is laminated between optical layers. A low-voltage signal from the temple electronics changes molecular alignment inside the film, darkening or lightening the lens in under a second. Eclipse™ lenses shift tint density across a measured transmission range; Prismatic™ lenses shift both density and hue.

Music Shield Gen 2: 63%–17%. Aura and Aura Audio: 65%–20%. Dusk Classic: 38%–4%. Zurix: 50%–10%. Every lens blocks 100% of UVA and UVB at any tint level, so protection is never dependent on lens state.

Tint-only models draw power only during a transition, not while holding a tint state — so typical use spans several days per charge. Audio models depend on playback hours. Zurix reaches approximately 80% charge in about 80 minutes using the supplied magnetic cable.

Sport platforms including Music Shield, Shield and Golf Shield are IPX4 rated, covering sweat and rain splash. They are not designed for submersion, swimming or water sports with impact entry.
