LUKA magnifying lens. Our standard (for single vision) CR 39 lenses are made from a lightweight and resilient optical polymer that is almost as clear as glass but even lighter. The CR39 provides stellar optical quality and are free on most frames. They can be easily upgraded to include scratch resistant, UV and anti-glare coating.
We use free-form lenses (also called digital high-definition lenses) that are leading the industry standard. Our lenses are optimized with computer-controlled surfacing equipment that is much more precise than conventional tools.
