Material: CR-39 (Columbia Resin 39), a lightweight plastic material commonly used for eyeglasses.
Thickness: Thicker than high-index lenses but lighter than glass.
Durability: Decent impact resistance but less than polycarbonate or high-index materials.
Progressive Design: Provides a seamless transition between distance, intermediate, and near vision without visible bifocal lines.
Computer-Friendly Optimized for mid-range vision, reducing eye strain when working on digital screens.
UV Protection: CR-39 lenses naturally block some UV rays but may need an additional coating for full protection.
Anti-Reflective Coating (Optional): Helps reduce glare from screens and overhead lighting, enhancing visual comfort.
