Start with fit: look for a frame width and bridge that sit comfortably on your nose and temples. Then pick a lens color and UV protection level that match your typical lighting and climate, keeping in mind Aviator frames are metal and often have adjustable nose pads for a secure fit.

Key attributes include lens polarization (polarized vs. non-polarized), 100% UV protection, lens tint/color, and frame size/fit (lens width and nose bridge). Also consider coating durability and whether the metal frame includes adjustable nose pads for comfort.

For driving, glare-reducing properties improve visibility; for outdoor activities, choose a tint and coating that withstands glare and wear; for daily wear, comfort features like a secure nose pad and balanced weight matter.

Check the frame’s lens width and bridge size and compare them to your facial measurements. A comfortable fit should rest lightly on the nose and sit evenly across the temples without pinching.
