These 1.56 Photo Grey/Brown Invisible Bifocal lenses integrate photochromic technology, automatically darkening under sunlight while remaining clear indoors. Combining the convenience of bifocal vision with the protective benefits of color adaptation, these lenses are perfect for users who frequently move between indoor and outdoor environments. Available in round top and flat top designs, they provide seamless near and distance vision without visible lines. Ideal for outdoor enthusiasts and professionals alike, the grey or brown tint ensures natural color perception while reducing glare, making daily activities like driving, reading, or working under changing light conditions more comfortable. Lightweight and durable, these lenses balance aesthetic appeal and functional performance.
