The Lockhart sunglasses are half the weight of similar styles from other brands and the perfect combination of iconic looks and futuristic performance technology. They appear to be quite substantial but are in fact extremely lightweight for all-day comfort.
Borrowing from ROKA's award-winning performance sunglasses, the frames of the Lockhart feature ultra lightweight TR-90 nylon, which are lighter than acetate or polycarbonate, nearly unbreakable in daily use, and impervious to chemicals.
They have integrated spring hinges, which last longer than traditional barrel hinges and flex with different head shapes. The Lockhart also features ROKA's propriety GEKO™ technology, both in the temple grips and in their patented, interchangeable nose pads. GEKO™ is a hydrophilic compound designed to get tackier when wet or sweaty, which helps our glasses stay in place when you're active – working out, hiking, bending down to pick up the groceries, or playing with your pets or kids.
At the end of the day, all of this tech is meticulously engineered to deliver the performance you'd expect from sport glasses without having to look like you are about to step onto a racquetball court.
Our ultralight nylon lenses offer best-in-class, razor-sharp optics with anti-scratch, anti-reflective, anti-fog, hydrophobic and oleophobic coatings.
Booker’s TR-90 nylon frame and beta-titanium temples won’t warp, and are significantly lighter, stronger, more durable and chemical resistant than industry-standard materials like acetate. The striking architecture of the top of the frame is designed to offer additional protection from overhead light and features a small vent precisely engineered to improve airflow.
