Focus on fit (eye size, bridge width, temple length) and confirm you can get the lenses you need (prescription, anti-reflective, or blue-light blocking).

Brand/style preference, frame material (acetate vs metal), lens options (prescription or non-prescription and coatings), and the tortoise color pattern, plus warranty/returns.

Consider weight and durability for all-day comfort, coatings for glare reduction and UV protection, and whether the lens setup suits screen time or blue-light needs.

Choose frames with larger lens openings and wider temples for a balanced fit, and ensure the frame supports thicker or progressive lenses and offers prescription options from brands like Oakley, Tom Ford, or BOSS.
