Product Overview


Sight Correction 

High-quality sports eyewear protects the eyes and ensures first-class vision. For sports enthusiasts who rely on corrective lenses, adidas eyewear's RXO concept offers a range of options for optical correction.  RXO stands for RX OPTOLOGY. The concept is tailored to individual needs and different sports.  The athlete has the option of turning an awesome pair of sports sunglasses into prescription sports sunglasses with this Performance Insert, ensuring optimal performance through optimal vision.

Most of the adidas eyewear sports performance range is designed to be able to quickly integrate an optical insert. The optical insert can be easily secured on the bridge behind the filters in a very stable way. Due to this positioning, the rimless insert is virtually invisible.

This product is the Flexible Rimless Insert, the lenses are attached to the soft nose piece, which is attached by replacing the original nose piece from the frame.  Please note that the actual product may differ slightly from that shown in the images above.

See the example in the video below.
