Focus on fit first—check lens width, bridge size, and temple length to suit your face. Then consider the finish and material (gold-tone metal) and whether you need prescription lenses.

Key attributes include frame material and build quality, size measurements (lens width, bridge width, temple length), nose pad type, and lens options (UV protection, coatings, or suitability for prescription lenses).

Consider daily wear vs. occasions, whether you need prescription lenses, anti-reflective coatings, glare reduction, and comfort features like adjustable nose pads or spring hinges.

For a classic luxury look, choose established brands like Saint Laurent or Gucci; for versatility or a sportier feel, Carrera or Calvin Klein offer different fits. If you need prescription lenses, select frames labeled RX-ready.
