Xperio polarized sunwear gives you better protection and comfort than tinted and clear lenses can achieve.

As you can see on the following table, ordinary tints can reduce brightness and provide 100% UV protection (if they are properly coated), or depending on the lens material), but only Xperio polarized lenses eliminate bothersome glare and can offer a superior visual comfort. Clear lenses are definitely not efficient for your outside activities!
