Our SVED Rx Insert is specially designed to perform with popular 100%, Oakley, and Pit Viper models like the Hypercraft, S2/S3, Sutra, EV, and The Original 2.0. Instead of replacing your original lenses, we add lightweight, rimless prescription lenses that fit securely onto your nose pad behind your sunglass lens—preserving both the original style and performance. It’s also ideal for high prescriptions, adventure, and competition.
