Start with fit: check frame width, bridge size, and temple length, then pick a color and finish that complements your wardrobe. A square shape often works with oval or heart-shaped faces but try a size that feels balanced on your features.

Look at frame material and weight, overall dimensions (eye size, bridge width, temple length), lens type (single-vision or progressive), and coatings like anti-reflective or blue-light protection for everyday comfort.

Yes. For computer work, prioritize blue-light filtering and anti-reflective coating; for reading, consider lighter frames and possibly smaller lenses; for general daily wear, focus on comfort and fit.

Compare fit specs (eye size, bridge, temple length), frame material, and available lens options; brand styling matters for color and weight, and ensure your prescription is compatible with the chosen lenses and any warranty.
