Focus on strong UV protection, the lens type (polarized vs non-polarized), and the frame material—prefer eco-friendly options. Also consider how the fit works with a rectangular shape for your face.

Key attributes to compare are UV protection (aim for UV400), lens type (polarized lowers glare), and the sustainability of the frame material. Size and fit also influence comfort and coverage.

Think about when you’ll wear them (driving, outdoor activities, daily use), comfort factors like weight and nose bridge design, and care options such as cleaning, replacement parts, or warranty.

Go for polarized lenses with strong UV protection to reduce glare, and choose a secure-fit frame that stays in place during movement.
