Start with the frame width and eye size to ensure a balanced sit across your brows; rectangular frames suit many face shapes, but a good fit should feel comfortable all day.

Look at frame size (eye size, bridge, temple length), material and weight, and lens options (prescription type and coatings) to match your needs.

Consider lightweight materials, adjustable nose pads, and coatings like anti-reflective or blue-light protection for screen use.

If you need reading glasses, prioritize single-vision reading lenses; for distance, ensure the correct distance prescription; for mixed-use, consider progressive lenses or coatings suited to daily activities.
