Engineered for the digital age, this premium 1.60 refractive index semi-finished lens blank combines advanced blue light protection with superior optical performance. The high-quality resin material features built-in selective filtration technology that blocks 30-45% of harmful high-energy blue light (400-455nm) while maintaining optimal color perception and visual clarity. With its semi-finished design, optical labs can precisely customize the front surface with spherical, aspheric, or freeform curves to create perfectly tailored single vision prescriptions.
