For our more technical sunglasses (KETYUM™, RYDON SX™, RYDON ™, EKYNOX SX™, KALYOS ™, WIZAARD ™) that cannot support a direct in frame RX, Rudy Project has created CLIP-ON RX optical inserts that can be snapped in behind the polycarbonate Rudy Project lenses. Thanks to our patented ‘easy-in easy-out‘ system; our Clip-ons can be inserted or removed with ease. This is particularly useful when you want to wear your contact lenses or when cleaning.
