Start with fit and prescription compatibility. Silver rectangle frames suit many face shapes, but ensure the lens width and bridge size match your measurements for comfortable all-day wear.

Key attributes are frame size (lens width and bridge), material and weight, and lens options (prescription compatibility, anti-reflective coating, blue-light blocking, or photochromic). Also check hinge durability for daily use.

Think about your main activities: for reading or computer work, choose lenses suited to near/intermediate distances (progressives or near-focused lenses) and look for comfort features like nose pads and temple grip for all-day wear.

Prioritize comfort and lens features such as blue-light blocking and a lightweight frame; consider lenses with UV protection or photochromic options if you move between indoor and outdoor lighting.
