Polarized vs. Photochromic Sunglasses: Six Checks Before Driving

Polarized lenses reduce reflected glare, while photochromic lenses respond to changes in light. Some lenses do not darken sufficiently behind car windshields, so confirm the exact model. The previous description of real sunglasses photographs and a photographic lens experiment was inaccurate. The previous cover was an AI-generated thematic illustration, not an actual product photograph or lens test. Use the linked original REI and ZEISS guides for reference.
