Start with fit and comfort: pick a frame size that matches your face width and bridge size; ensure the temple length feels comfortable behind your ears.

Look at frame size (lens width and total width), bridge width, material and weight, and lens features such as clear lenses with UV protection or coatings.

Consider coatings (anti-reflective or scratch resistance), durability of the frame material, and whether you need prescription compatibility or blue-light filtering.

Choose smaller frame models and lighter materials (thin acetate or metal) with adjustable nose pads for comfortable all-day wear.
