The Altalist Legacy 3 sunglasses are stylish sports glasses that you can wear with either polarized or photochromic lenses! You will find 2 types of lenses in the package - then just click and re-click the sides and you're done!
Polarized lenses eliminate reflections of the sun's rays from the road, water surface or snowy surfaces. They have a CAT 3 filter category , so you can wear the glasses without worry even during the hottest summer days. The photochromic ones , on the other hand, react to UV light and thus adapt their color to the current weather. The solar filter category of these lenses  ranges from CAT 0 to CAT 2 .
The durable Grilamid TR90 frame is incredibly light and adapts perfectly to the contours of the face thanks to the adjustable beam and rubberized sides . Because the glasses are rounded, they also cover your peripheral vision and provide you with a perfect view. And to top it all off, the package also includes a preparation for dioptric lenses , which can be easily attached to the inside of the glasses. The equipment is complemented by a hard and fabric case , as well as a microfiber cleaning cloth .
