The source uses “Polaroid” in its lens-material field but does not identify a specific lens composition. The images also describe a solar-powered control chip and a 0.1-second tint-change claim; no test details are supplied, so that response time is not guaranteed. Confirm the actual tint range and suitability for driving, including use behind a windshield.
