Transitions Signature GEN S

Transitions Signature GEN S is the everyday option: clear indoors and darkening automatically in sunlight, then fading back to clear quickly once you're back inside.

It blocks 100% of UVA and UVB rays and filters blue-violet light both indoors and out, on top of vision correction, and comes in 8 colors, from everyday neutral shades to more expressive style colors.

Transitions XTRActive is built for wearers who are especially light-sensitive or spend a lot of time in bright light. It's clear with a hint of protective tint indoors, and reaches the darkest levels of any Transitions lens outdoors — up to category 3, sunglass-level darkness, even in hot weather.

Unlike standard photochromic lenses, XTRActive also activates behind a car windshield, darkening for extra protection while driving, since it doesn't rely solely on direct UV exposure to darken. It filters up to 7 times more blue-violet light than a clear lens indoors.

Transitions XTRActive Polarized combines photochromic light adaptation with dynamic polarization: the lens darkens and polarizes together as it activates outdoors, reaching up to 90% polarization efficiency — similar to dedicated polarized sunglasses.

It's clear indoors with just a hint of protective tint, and activates behind a car windshield like other XTRActive lenses, darkening for driving without polarizing (since polarization needs direct UV exposure that a windshield blocks). A strong option for patients bothered by reflected glare off water, snow, or roads.
