Computer Eyed's Lined Bifocal Lens contains a two-power lens that corrects for both reading and computer vision. These lenses feature a visible line separating the reading and vision powers.

Our Blended Bifocal Lens provides a dual power lens correction for reading and computer vision. The Blended Lens contains no visible line on the lens, as the separation between reading and vision powers is blended within the CR-39 plastic lens. Any Computer Eyed product containing 'no-line' in the item description, will feature our blended bifocal lens.
