No, the three variants of the UA Assist 2 carried here (Matte Black / Blue Mirror, Shiny Black / Emerald Mirror, and Matte Black / Gray) are not polarized. They provide 100% UVA and UVB ray protection and reduce visible light transmission through tinted and mirror-coated lenses, but they do not use polarizing film to eliminate horizontal glare. If glare reduction on water, snow, or reflective pavement is a priority, look for a polarized option in the Under Armour lineup.

The UA Assist 2 has a 57mm lens width, a 17mm bridge, and 140mm temple length, sized for a Medium-Large fit. These measurements indicate how wide each lens is, how wide the gap between the lenses sits at the nose, and how long the temple arms extend to your ears. If you already own glasses, you can find these same numbers engraved on the inside of your current temple arm to compare. Most adults with a medium to large head size will find the fit comfortable, and the rubberized nose pads and auto-lock hinge provide additional adjustment range.

Mirror-coated lenses feature a thin metallic reflective layer applied to the outside of the lens, which reflects additional light away from your eyes on top of the underlying tint. Standard tinted lenses absorb light without reflecting it. Mirror lenses typically look more striking from the outside and can perform well in very bright conditions such as open water, snow, or direct summer sun. Standard tinted lenses, like the Gray option in this lineup, offer a lower-profile look and can be more versatile across varying light conditions. Neither type is inherently superior; the right choice depends on your typical environment and personal preference.

Tritan Renew is a BPA-free recycled co-polyester plastic developed from post-consumer and post-industrial waste, with up to 50% recycled content by composition. For sunglasses frames, it delivers the same durability, flexibility, and impact resistance as conventional TR90 plastic while reducing reliance on virgin petroleum-based materials. The result is a frame that resists cracking under flex, does not cause allergic reactions in most wearers (hypoallergenic), and carries a lower environmental footprint. Under Armour uses Tritan Renew across both the front frame and the temple arms of the UA Assist 2.
