Start with fit and lens needs: pick a frame size and bridge width that fit your face, and decide if you need reading, distance, or progressive lenses.

Lens type and prescription compatibility, frame size and comfort (weight and material), and coatings such as scratch resistance and UV protection.

Consider daily wear vs. occasional use and how easy they are to maintain. Silver frames tend to be versatile, while some brands offer more distinctive silhouettes.

Are you mainly reading at a desk or using glasses all day? Do you prefer a subtle, classic frame or a more distinctive silhouette? Do you want coatings like blue-light filtering or extra scratch resistance?
