Choose the right frame size so they sit comfortably on your face. Look for a durable build and a red rectangle style that flatters your features, and check coatings (like anti-scratch or anti-reflective) and whether you need prescription lenses.

Frame size (eye width and bridge), material and weight, lens options (clear, tinted, or prescription), and coatings or UV protection.

Consider comfort features (nose pads, hinges), durability, and whether you need lenses tailored for your activity (blue-light filtering for screens or darker tints for sunny days).

Look for frames that accommodate prescription lenses and offer blue-light filtering if you view screens frequently; ensure the frame can hold the correct lens thickness and provides a comfortable fit for extended use.
