The temple tips can be adjusted in any direction by applying gentle pressure. Rudy Project employs no-slip components that do not fail in the heat of the moment. This unique technology ensures maximum comfort, a perfect fit during any use and eliminates fogging and pinching.
Safety Project is a unique Rudy Project feature that creates fold-in-hinge without any sharp edges. Designed to minimise injury in case of impact or falls.
IMPACTX™ has lower refractive index, internal stress and chromatic dispersion than polycarbonate, resulting in sharper images, higher definition, reduces “rainbowing”, and more visual comfort. Unlike polycarbonate and polyamide , IMPACTX™ is not attacked by common chemicals or solvents.
In the event of a fall or a collision IMPACTX™ are guaranteed not to break or crack. Furthermore they are 16% lighter than CR-39 and 10% lighter than Polycarbonate.

For more technical sunglasses that can't support a direct in-frame prescription, Rudy Project has created CLIP-ON RX optical inserts that can be snapped in behind the Rudy Project lenses. The Clip-ons can be inserted or removed with ease. This is particularly useful when you want to wear your contact lenses or when cleaning.
