Jasper is Vision's most popular frame model, featuring a casual style and a width of 141 mm. Polarflite lenses filter surface glare with Actif tri-acetate lenses, while Mirrorflite adds a darker mirror coating for bright days. The Photoflite and PhotoCarbon versions darken in UV light; PhotoCarbon uses a lighter, impact-resistant polycarbonate. On the water, lens color choice remains crucial: brown for color accuracy and contrast, yellow for evenings or overcast conditions, and amber to improve reading in low light. Photochromic lenses are not suitable for driving, as the windshield blocks some of the UV rays needed for them to darken.
