This high-performance 1.60 refractive index semi-finished lens blank offers superior optical clarity and durability for customized single vision prescriptions. The semi-finished design allows optical laboratories to precisely customize the front surface with either spherical or aspheric curves to meet individual prescription requirements. Featuring built-in 100% UV protection up to 400nm and an Abbe value of 36-40 for reduced chromatic aberration, this lens blank delivers sharp, distortion-free vision.
