This photochromic bifocal lens series provides optimized vision for both distance and near needs, making it ideal for individuals with presbyopia or those in need of dual-focus eyewear. Available in both Round Top and Flat Top bifocal segment styles, these lenses allow for clear vision at multiple distances, eliminating the need to switch between different pairs of glasses. The Photo Grey and Photo Brown photochromic technology automatically adjusts to changing UV light, offering sun protection outdoors and crystal-clear vision indoors.

The invisible bifocal design seamlessly blends the near and distance zones, reducing visual jumps and enhancing everyday comfort. With a refractive index of 1.56 and a variety of coatings (UC, HC, HMC, SHMC), these lenses can be customized to meet both prescription and environmental needs.
