Think about how you run and your typical weather. Look for a secure, comfortable fit, UV protection, and lenses that reduce glare and stay clear during activity.

Lens quality (UV protection and glare reduction), fit and stability (wraparound feel and non-slip nose pads), and frame size/coverage that suits your face and running style.

Consider lens tint to match light conditions, polarization to reduce glare, and features like anti-fog or lightweight materials to improve comfort during long runs.

In bright sun, choose a darker tint with strong glare protection and a secure fit; for dawn or overcast days, prefer a lighter yet higher-contrast tint and a frame that stays put during movement.
