Our Blue Cut UV420 Invisible Bifocal lenses offer the perfect blend of classic bifocal functionality and cutting-edge blue-light protection. With a 1.56 refractive index, these lenses come in both Round Top (RT) and Flat Top (FT) segment designs, providing seamless near-vision support while keeping your distance vision crystal clear.
Unlike traditional bifocals with visible lines, the invisible segment design gives these lenses a sleek, modern appearance, ideal for those who need separate near and far correction without compromising style. Plus, the Blue Cut UV420 technology filters harmful blue light and UV rays up to 420 nm, reducing digital eye strain even after long hours in front of screens.
