Setup, Compatibility & Care
To ensure your Ray-Ban Erik Optics last, take them to a professional optician for initial lens installation and frame adjustment. The 49-19 sizing indicates the lens width and bridge width in millimeters, which is crucial for achieving an optimal fit; consult with an optical specialist to verify this aligns with your pupillary distance (PD). Care involves cleaning the lenses with a microfiber cloth and a mild, alcohol-free lens spray. Avoid leaving the frames in high-temperature environments, such as a hot car dashboard, as extreme heat can compromise the integrity of the frame material and lens coatings. Always store them in a protective hard-shell case when not in use.
