For runners who wear prescription glasses, sports sunglasses have often involved a degree of compromise. Visual distortion, dizziness and an uncomfortable fit can affect the overall experience, turning eyewear into a potential distraction. Vycoz aims to address these challenges with Performance Sun, featuring its dedicated RX Clip system. The sports eyewear is designed to maintain a familiar visual experience for prescription wearers while providing the stability and fit required for active use.

Performance Sun combines a 4-curve lens design, comparable to that found in everyday eyewear, with precision-fit engineering. The frame structure has been calculated to minimize contact with the eyebrows while maintaining a secure and natural fit. Weighing approximately 19g, the lightweight construction is designed to help maintain stable vision during dynamic movement, allowing runners to remain focused on their activity.

At the centre of the design is Vycoz's RX Clip system. Its precision-fit structure minimizes the distance between the eye and the front surface of the clip lens, reducing it to approximately 12mm. With Performance Sun, Vycoz extends its approach to precise fit and balanced design into active eyewear, focusing on the specific requirements of prescription wearers who want reliable vision and comfort while running.
