Built with a plastic, full‑frame design and polycarbonate lenses, these glasses provide 99.9% UVA and UVB protection and feature a hard coat finish to resist scratching in daily work environments. An adjustable rubber nosepiece and dual‑molded rubber temple grips help maintain a secure, comfortable fit during extended wear, while the lenses are described as 100% visually correct, supporting clear, unobstructed vision across tasks.

Key construction details include a crystal black/silver mirror lens color and a robust, scratch‑resistant polycarbonate lens paired with a lightweight frame.
