FERDI was developed with the purpose of providing the ultimate peripheral vision (185°), with a cylindrical-style design. FERDI sits closer to your face, which allows for better periphery vertically and horizontally. FERDI XEp feature a photochromic lens that automatically adjusts to all weather conditions.  It changes from a royal blue lens in sunny conditions to a transparent purple in overcast weather within seconds.
