Look for sustainable frame materials (like bio-based acetate or recycled metal), lenses with UV protection and anti-scratch coatings, and a comfortable, well-fitting size.

Compare material composition, lens options (UV protection, optional polarization or blue-light protection), frame size (width, bridge, temple length), weight, and price.

Consider whether you’ll wear them indoors, outdoors, or at a computer; look for blue-light protection, prescription compatibility, and style or color preferences.

Evaluate eco-certifications, material quality, fit, warranty, and whether the option supports your prescription or specific needs (e.g., blue-light or readers).
