Carrera has introduced three new products, the C-ALU3, C-TF02 and R&B X-Lite, all touted as being ergonomic. The multiple position system allows the wearer to adjust the width and height of the nosepiece; the end pieces are adjustable; and the nosepieces and temples are coated in Megol, a hypoallergenic rubber that helps keep the glasses in place even in the rain or in sweaty conditions.
