  • What is Sharp Vision then?

    In sharp vision, light focuses directly on the retina, providing clear images at all distances. The eye’s lens adjusts to maintain sharpness both near and far, eliminating the need for corrective lenses. The sharp vision lenses are plain tempered glass lenses without any diopter correction for nearsighted or farsighted.
